The required tension in the cable when the elevator accelerates down at a rate of 3. 7 m/s2 is  143163.26 N.

The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.

We have,

Weight = 230000N, Mass of elevator = 23469.38 kg

a = 3.7 m/s^2

So, by free body concept

230000 - T = 23469.38 kg(3.7)

230000 - T = 86836.74

T = 143163.26 N

Thus, required tension in string is  143163.26 N.

Answer: Option (a)

Solution: The covalent bond is best described as the bond where one atom shares its electron(s) with another neighboring atom to become stable. Here, the word “co” represents jointly and “valent” represents valency shared by them. Therefore, option (a) is the most appropriate choice amongst all the provided options.

The energy of the ball has been reduced by 0.98 joules (option A) after bouncing back because potential energy has been transformed into kinetic energy (option A).

Potential energy is the energy possessed by an object because of its position while kinetic energy is the energy possessed by an object because of its motion.

According to this question, a ball with a mass of 0.5 kg is lifted to a height of 2.0 meters and dropped. It bounces back to a height of 1.8 meters. The difference in potential energy can be calculated as follows:

P.E (1) = 0.5 × 2 × 9.8 = 9.8J

P.E (2) = 0.5 × 1.8 × 9.8 = 8.82J

∆P.E= 9.8 - 8.82 = 0.98J

This reduction occured because the potential energy of the ball changes to kinetic energy (in motion).

Explanation:

Since the speed of sound in water is known, the simple equation "d/2 = vt" is used to find the depth "d".

On a velocity-time graph, the object's displacement is indicated by the area under the line. The distance is the zone under a speed-time graph.

Displacement is the outcome of velocity and time. The area of our graph is obtained by multiplying the velocity and time, which is virtually equivalent to multiplying two lengths. The solution to estimating displacements from a velocity-time graph.

The amount of acceleration will be determined by the graph's slope. Example If a particle's acceleration is constant (k) and positive, its starting velocity is zero, and it grows linearly from there. The acceleration will be determined by the velocity-time graph's slope.

The gravitational field strength on Oobla is 20.8 N/kg. It is greater than the gravitational field strength on Earth.

The gravitational field strength, also called acceleration due to gravity or free-fall acceleration, is the gravitational force that acts on a mass of object. It can be expressed as

g = F/m

Where

The gravitational force can be stated as weight of object W. The formula becomes W = mg. So, the weight of an object depends on the gravitational field strength on a place.

An object has a weight of 170 N on Earth. The weight becomes 360 N on Oobla. Find the gravitational field strength on Oobla!

We know that the gravitational field strength on Earth is 9.8 N/kg.

Let's say:

The mass of an object is always the same wherever it is.

So, the gravitational field strength on Oobla is

m = W/g

m₁ = m₂

W₁/g₁ = W₂/g₂

170/9.8 = 360/g₂

g₂ = (9.8×360)/170

g₂ = 20.8 N/kg

It is greater than the the value of g on Earth.

Hence, the planet Oobla has the gravitational field strength of 20.8 N/kg.

The train starts from rest and moves through a distance of 1 km in 100 km with a uniform acceleration. The formula for velocity at the end of a certain time period is calculated by the following formula:

where:

v = final velocity (speed)

u = initial velocity (0 m/s, since the train starts from rest)

a = acceleration (0.01 m/s^2)

t = time (100,000 seconds, since the train travels 1 km in 100 km)
