To calculate the magnetic induction inside the cylinder, we can use the following formula:
B(r,θ,z) = μH(r,θ,z)
where B is the magnetic induction, μ is the permeability of the material, and H is the magnetic field strength.
Since the cylinder is long and has a uniform radius, we can assume that the magnetic field strength is only a function of the z-coordinate. Additionally, since the cylinder is placed perpendicular to the magnetic field, the z-component of the magnetic field is equal to the external magnetic field strength B.
To determine the magnetic induction inside the cylinder, we need to solve for the magnetic field strength H. We can use the fact that potentials can be completely specified in terms of cos(o) cylindrical harmonics. This means that we can express the magnetic field strength as:
H(r,θ,z) = ∑(n=0 to ∞) [An cos(nθ) + Bn sin(nθ)] Jn(kr) cos(o)
where Jn is the nth order Bessel function and k is a constant that depends on the external magnetic field strength B and the permeability μ.
Using boundary conditions, we can determine the coefficients An and Bn and ultimately find the magnetic induction inside the cylinder.
In summary, to calculate the magnetic induction inside a long cylinder of radius a and permeability μ placed perpendicular to a uniform magnetic field B, we can use the formula B(r,θ,z) = μH(r,θ,z), express the magnetic field strength in terms of cylindrical harmonics, and use boundary conditions to determine the coefficients and ultimately find the magnetic induction inside the cylinder.

True or False:
Sensations of heaviness and lightness are always associated with changes in a person's weight. A person who feels light has lost weight and a person who feels heavy has gained weight.
If False, explain why the statement is false.
If True, explain why the statement is true.
It's not true, no. The weight can be used to calculate an object's product of mass, but not gravity. The object's mass is multiplied by gravity, as is evident. However, an object's mass will never be 0 and will always be constant, its weight would be zero if there is no gravity. Since mass and weight are not the same, the assertion is untrue.
What is Weight?Weight is the gravitational pull of a large second object, thus the Moon or the Earth, at the first object. Weight is a result of the universal law of gravity, according to which any two objects will gravitationally pull one another with a force exactly equal to the applied of their masses and divided by the square of a distance separating them.
Because of this, larger items naturally weigh more when placed in the same spot; yet, the farther any object seems to be from the Earth, the less weight it has.
Because of the tiny difference in size between the polar and equatorial radii of the Earth, an object's weight at the South Pole is somewhat higher than its value at the Equator.

A wave hits an object as shown. A vertical line with Medium 1 to the left and Medium 2 to the right. An arrow from the left reaches the line. An arrow starts from the same point on the line and goes right at a different angle. Which kind of wave interaction is shown?
Answer:
refraction
Explanation:
When the wave moves from medium 1 to medium 2, then the wave gets refracted. Then the correct option is C.
What is the wave?A wave is an energetic disturbance in a medium that doesn't include any net particle motion. Elastic deformation, a change in pressure, an electric or magnetic intensity, an electric potential, or a change in temperature are a few examples.
A wave is a dynamic disturbance of one or more variables that propagates in physics, geometry, and related sciences. When waves oscillate frequently around an equilibrium value at a certain frequency, they are said to be periodic.
The bending of waves as they go from one substance to another is known as wave refraction. It bends when the wave enters a new material because the wave's speed changes. The optical density or index of refraction of the material affects how light waves bend.
Thus, the correct option is C.

1. A stone is thrown upwards with an initial velocity of 25 m/s at angle of 30° to the ground a. Show that the vertical component if the velocity at the starting is 12.5 m/s upwards.
The vertical component of the velocity at the starting is 12.5 m/s upwards.
What is velocity?Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time.
In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.
Given that stone is thrown upwards with an initial velocity of 25 m/s at angle of 30°.
Hence, the vertical component of the velocity in upward direction = 25 sin30° m/s
= 25 × 1/2 m/s
= 12.5 m/s.

The seed planted at extreme cold or in the region of frozen ice do not germinate, why?
Answer:
yes
The the seed planted at Extreme cold or in the region of frozen I did not germinate because the amount of moisture of the seed is too high which results in lack of air of the sea in the frozen ice
In fact, a soil temperature below 50°F might be problematic for many garden plants. Seeds will quickly absorb water at 40°C, but they won't begin to grow. This presents a risk for rot and disease, which may cause damping-off or subpar growth.
What is germination of seed?The formation of the seedling is the consequence of germination, which is often the growth of a plant inside a seed. It is also the process of the seed's metabolic machinery being reactivated, which causes the radicle and plumule to emerge. A vascular plant's seed is a little bundle that develops in a fruit or cone as the result of the union of the male and female reproductive cells.
Given the need for particular internal or external stimuli to resume growth, dormant seeds are viable seeds that do not germinate. When the right circumstances are present, the seed starts to germinate and the embryo starts to grow again, eventually becoming a seedling.

2, A rectangular Container of base 50 cm by 30cm is filled with water to be depth of 5cm. how much is the pressure exerted at the base? (take pw= 1000kg /m3 and g=10m/s)
Answer:
P = 500 N/m²
Explanation:
Pressure exerted at the base is the hydrostatic pressure and it is given by the formula;
P = ρgh
Where;
ρ is density = 1000 kg/m³
g = 10 m/s²
h is depth = 5 cm = 0.05 m
Thus;
P = 1000 × 10 × 0.05

Choose ALL that apply.
A) R makes up Q which makes up P which makes up S.
B) Cells that work together make up tissues, which comprise organs.
C) Similar cells working together make up organs which make up organ systems.
D) In the model, the animal cells make up tissues such as muscle or connective tissue.
E) Organs, such as the stomach and intestines, make up organ systems which interact with one another to maintain homeostasis.
The model that depicts the concept of biological levels of an organization which is ranging from single organelle to biosphere is explained by all the options given except for options A and C.
Biology is specifically the study that deals with various forms of life. Since life is considered a vast topic, scientists classified this broad system into different organizational levels for better understanding.
The Biological levels of the organization are described as follows:
The biological level of organization of any living form is depicted and arranged from the simplest forms to the complex ones and thus, the order tends to start from organelles to the biosphere. The elaborated levels are in ascending order as organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere respectively. Each level tends to combine with one another to give rise to the next level. One such example is that the cells that tend to work together make up the tissues, which further comprise the organs. Similarly, organ systems are formed by the interaction between certain organs in order to maintain homeostasis.
Considering all these facts, option C represents the statement that is incorrect as the cells cannot directly form organs without forming tissues and the letters in option A is not specific. And thus, we can conclude that except for options A and C, all the other options correctly depict the model of the Biological levels of the organization.
