A patient's far point is 115 cm and her near point is 14.0 cm. In what follows, we assume that we can model the eye as a simple camera, with a single thin lens forming a real image upon the retina. We also assume that the patient's eyes are identical, with each retina lying 1.95 cm from the eye's "thin lens."a.) What is the power, P, of the eye when focused upon the far point? (Enter your answer in diopters.)b.) What is the power, P, of the eye when focused upon the near point? (Enter your answer in diopters.)c.) What power (in diopters) must a contact lens have in order to correct the patient's nearsightedness?

Answers

Answer 1

The power of the eye when focused on the far point is: P = 1 / (0.0087 m) = 115 diopters  , The power of the eye when focused on the near point is: P = 1 / (0.015 m) = 67 diopters , The contact lens should have a focal length of 0.021 meters, or 2.1 cm.

a) The far point is the distance at which the eye can see objects clearly without accommodation, meaning that the lens is not changing shape to focus the light. This means that the far point is the "resting" point of the eye, and we can use it to calculate the power of the eye's lens using the following formula:

P = 1/f

where P is the power of the lens in diopters, and f is the focal length of the lens in meters. Since the eye's far point is 115 cm away, the focal length of the lens is:

f = 1 / (115 cm) = 0.0087 m

So the power of the eye when focused on the far point is:

P = 1 / (0.0087 m) = 115 diopters

b) The near point is the closest distance at which the eye can see objects clearly, and it requires the lens to increase its power by changing shape (i.e. by increasing its curvature). We can use the near point to calculate the power of the eye when it is fully accommodated, using the same formula:

P = 1/f

where f is now the focal length of the lens when it is fully accommodated. Since the near point is 14 cm away, we can calculate the focal length as follows:

1/f = 1/115 cm - 1/14 cm

f = 0.015 m

So the power of the eye when focused on the near point is:

P = 1 / (0.015 m) = 67 diopters

c) To correct the patient's nearsightedness, we need to add a diverging (negative) lens that will compensate for the excess power of the eye when it is fully accommodated. The power of this lens can be calculated as follows:

P_contact = -1 / f_contact

where P_contact is the power of the contact lens in diopters, and f_contact is its focal length in meters. We want the lens to correct the eye's excess power by an amount equal to the difference between the power of the eye when focused on the far point and when focused on the near point, which is:

ΔP = P_near - P_far = 67 - 115 = -48 diopters

So the power of the contact lens should be:

P_contact = -1 / f_contact = -48 diopters

f_contact = -1 / P_contact = 0.021 m

Therefore, the contact lens should have a focal length of 0.021 meters, or 2.1 cm.

D The system performs 2.655 kJ of work on the surroundings.

Answers

The work done by the system is -2.655KJ. This states that the system performs 2.655KJ of work on the surroundings. Thus, the correct option is D.

What is work done?

Work done is defined as the product of force and the distance over which the force is applied on the object. Work is done when a force is applied to an object and the object experiences motion through a distance.

Given that the work is done on the surrounding, i.e., the work is done by the system and the heat is absorbed by the system.

Therefore,

ΔU = -5.155KJ

q = 2500J = 2.5KJ

Now from first law of thermodynamics,

ΔU = q + w

-5.155 = 2.500 + w = -2.655KJ

w = -2.655KJ

Hence the work done is -2.655kJ.

What will be the acceleration, if a vehicle started from rest and its velocity reached 20 m/s after 5 second? Calculate. Ans: 4m/s (2)​

Answers

Answer: 4m/s2 ✅

Explanation: A vehicle started from rest and its velocity reached 20m/s after 5 seconds. To calculate the acceleration, we can use the formula: acceleration = (change in velocity) / (change in time).

The change in velocity is 20m/s - 0m/s = 20m/s (the final velocity minus the initial velocity)

The change in time is 5 seconds (the time it takes for the velocity to change)

So the acceleration of the vehicle is (20m/s) / (5s) = 4m/s2✅

Answer: The acceleration of the car starting from rest is 4 m/s^2✅

Explanation:

It is an exercise of uniformly varied rectilinear movement.

What will be the acceleration, if a vehicle started from rest and its velocity reached 20 m/s after 5 second?

Data:

a = acceleration = ?

Vo = initial speed = 0

Vf = Final speed = 20 m/s

t = time = 5 s

The formula to calculate the acceleration is a = (Vf - Vo)/t, but it tells us that the car starts from rest, that is, it has no initial velocity, we clear the formula and we are left:

   a = Vf/t

   a = (20 m/s)/5 s

   a = 4 m/s²

The momentum of an isolated system before and after a collision must equal each other, according to the law of conservation of momentum.

In a collision, why does momentum remain constant?

The only thing that happens when two bodies collide is that their momentum changes. Thus, for bodies colliding, changes in momentum are always equal and opposite. The momentum of the other body must decrease by the same amount if the momentum of the first body increases. As a result, momentum always remains constant.

A solid cube of mass 87 kg and edge length 0.95 m rests on a horizontal floor as shown below. A person then pushes on the upper edge of the cube with a horizontal force of magnitude F. At what value of F will the cube start to tip? Assume the frictional force from the floor is large enough to prevent the cube from sliding.

Answers

The force required to tip the cube is equal to the coefficient of static friction times the weight of the cube.

fx=μs * 87 kg * 9.8 m/s^2

What is the force required to tip the cube?

Generally, The cube will start to tip when the net torque about the point of contact between the cube and the floor is equal to zero. The torque is given by:

torque = force x distance from axis of rotation

The distance from the axis of rotation is half the edge length of the cube (0.475m), and the force is the force applied by the person (). Therefore, the torque is:

torque = fx x 0.475

For the cube to tip, the torque due to the person's force must be greater than the maximum torque the friction can provide, which is the friction force times the distance from the axis of rotation.

The maximum torque provided by friction is:

friction torque = friction force x 0.475

Since the friction force is equal to the normal force (mg) multiplied by the coefficient of static friction (μs), the maximum torque provided by friction is:

friction torque = μs * mg * 0.475

where m is the mass of the cube, g is the acceleration due to gravity and μs is the coefficient of static friction between the cube and the floor.

So, we can find the force needed to tip the cube by equating the torque due to the force with that of the friction torque.

Fx*0.475 = μs * m * g * 0.475

Fx= μs * m * g

Fx= μs * 87 kg * 9.8 m/s^2

Note: The coefficient of static friction (μs) is a dimensionless quantity between 0 and 1, it varies depending on the surfaces in contact.

What is kinetic energy?

Kinetic energy is the energy an object possesses due to its motion. It is the energy associated with an object’s speed and mass, and is the energy that an object has because of its movement. Kinetic energy can be converted into other forms of energy, such as heat, light, or sound. It can also be used to do work, such as moving objects or powering machines. Kinetic energy is a form of mechanical energy, which is energy that is associated with the motion or position of an object. Kinetic energy is related to the work done on an object, and it increases as the object’s speed increases. Kinetic energy can be calculated using the formula KE = ½mv2, where m is the mass of the object and v is the velocity of the object.

The kinetic energy of the ball will increase as it falls, because it is gaining speed due to gravity.
As it falls, it accelerates at a rate of 9.8 m/s^2, and its kinetic energy is equal to its mass multiplied by the square of its velocity.

How does magnetic energy transform into
kinetic energy

Answers

Answer:

Magnetic energy can be transformed into kinetic energy in a variety of ways.

Explanation:

One way that this occurs is through electromagnetic induction. This occurs when a changing magnetic field induces an electric current in a conductor, such as a wire. This induced current creates a force that can move the conductor, thus transforming the magnetic energy into kinetic energy. This process is used in electric generators, which convert the kinetic energy of a turbine into electrical energy by turning a coil of wire inside a magnetic field.

Another way that magnetic energy can be transformed into kinetic energy is through the operation of an electric motor. An electric motor uses the interaction between a magnetic field and an electric current to create a force that can rotate a shaft, thus transforming the electrical energy into kinetic energy. Electric motors are used in a wide range of applications, including transportation, manufacturing, and household appliances.

Magnetic energy can also be transformed into kinetic energy through magnetohydrodynamics (MHD), which involves the interaction of a fluid with a magnetic field. When a fluid such as a gas or liquid moves through a magnetic field, it can generate a force that can propel the fluid, thus transforming the magnetic energy into kinetic energy. This process is used in some forms of propulsion, including maglev trains and MHD generators.

In summary, magnetic energy can be transformed into kinetic energy through the interaction of a magnetic field with a conductor, an electric current, or a fluid, which creates a force that can move an object, thus transforming the magnetic energy into kinetic energy.

An object is placed 4m above ground. The object has a mass of 4kg and the gravitational potential energy stored is 3J.
What is the gravitational field strength experienced by the object?
Give your answer to 2 decimal places.

Answers

Thus, g = GPE / (m*h) = 3 / (4*4) = 0.75 m/s2. Therefore, the gravitational field strength experienced by the object is 0.75 m/s2.

What is gravitational field strength?

Gravitational field strength is a measure of the gravitational force per unit mass at a given location in space.It is typically measured in Newtons per kilogram (N/kg) or meters per second squared (m/s2). Gravitational field strength is an important concept in understanding the effects of gravity on objects and how it affects their behavior.

It is represented by the symbol g and is calculated by dividing the gravitational force by the mass of an object. It is typically measured in units of meters per second squared (m/s2).

How can a protective device minimizethe magnitude of the net
force acting on an egg in a cart during a collision?

Answers

A protective device such as an egg carton, foam padding, or bubble wrap can be used to minimize the magnitude of the net force acting on an egg in a cart during a collision by providing cushioning some of the impact.

What is magnitude?
Magnitude
refers to the size or scale of an object, event, or phenomenon. It is typically used to describe the intensity or amplitude of a physical quantity, such as the strength of an earthquake or the brightness of a star. Magnitude is also used to quantify the size of a population, the severity of an economic downturn, or the power of a political movement. Magnitude is usually expressed as a numerical value, such as a number on a Richter scale or a magnitude rating on a star catalog. Magnitude can also be expressed in terms of a relative or subjective scale, such as a rating of “strong” or “weak” for an earthquake. Magnitude is often used in scientific research to quantify the size of a phenomenon, such as the magnitude of climate change or the magnitude of a new medical breakthrough.
