Passive heat absorption refers to multiple choice the cooling of solar panels used to generate electricity. using natural materials to gather and hold heat. using water to cool nuclear power plants.

The process of anything becoming totally absorbed into another substance is known as absorption. Adsorption and absorption are very independent processes that must not be confounded.

Any process by which a liquid or solid material penetrates the surface of another substance is known as chemical absorption. Intestinal absorption is the process by which the byproducts of digestion are transported from the gastrointestinal tract to the blood vessels, lymphatic system, and tissue cells.

A process known as absorption can be either chemically (reactive) or physically (non-reactive). A chemical response between the compounds being absorbed and those being absorbed is known as chemical absorption or reactive absorption.

(c) Energy come work done against conservative force

(d) K.E. as he hits the water is 612.5J

(e) His speed as he hits the water is

4.9 m/s

It is given that

mass of diver is 50kg

height of platform is 1.25 m

(a)

As it ascends Gravitational acceleration has an effect.

So,

→ w = ma

→w = 50 x 9.8

→ w = 490N

Hence, Diver weighs 490N pounds.

(b)

P. E = mgh

P.E. = 50 x 9.8 x 1.25 = 612.5J

The Potential Energy Change is 612.5J.

(c)

Potential energy come from work done against conservative force

(d)

Before a diver hits the ground, his K. E. is equal to the potential energy that is stored in it. because as one falls, potential energy is transformed into kinetic energy.

So, K. E = 612.5J

(e)

mv2/2 = 612.5J

50 x v² = 612.5 × 2

→ 50v² = 1225

The period of pendulum is still the same at 3.75 seconds.

We need to know about pendulum experiment to solve this problem. The pendulum is a simple experiment to calculate gravitational acceleration. The gravitational acceleration can be calculated by

g = 4π² . L / T²

where g is gravitational acceleration, L is the length of the string and T is the period.

From the question above, we know that:

L = 3.5 m

m1 = 0.3 kg

T1 = 3.75 s

m2 = 2m1

Find the period of pendulum

g = 4π² . L / T²

T² = 4π² . L / g

T = √(4π² . L / g)

The maximum velocity is v= √10gh/7

The energy that an object has due to its location in a gravitational field is known as gravitational potential energy. When an object is close to the surface of the Earth, when the gravitational acceleration can be assumed to remain constant at roughly 9.8 m/s2, gravitational potential energy is most frequently used.

For the situation of the maximum velocity of the sphere when it hits the ground, the loss in gravitational potential energy is equal to the gain in translational kinetic energy and rotational kinetic energy.

mgh = mv² x I / 2.

mgh = 0.5 mv² + 0.5 (2/5 mR²)

The no-slip condition results in:

v=Rω

mgh = 0.5 mv + 0.2 mv

The system that controls such body processes as hormone balance, temperature and width of blood vessels is called the endocrine system.

In coordination with the nervous system, the endocrine system controls and maintains balance in the organ system. It does this by secreting hormones. The nervous system sends a signal to the endocrine system which secretes hormones to coordinate different processes in the body.

Hormones are chemical substances that circulate round the body and bind to a target cell, where they elicit a response. Special organs called endocrine glands secrete these hormones directly into the blood stream. For example, the pancreas secretes a hormone called insulin, and another one called glucagon. These two hormones work together to control the glucose levels in the blood.

The reverse is not possible in this case

Heat can be produced entirely from mechanical energy.

When a moving object slides across an uneven, level surface and eventually comes to a stop, all of its mechanical energy has been converted to heat.

Additionally, if a moving object were to compress a frictionless piston filled with an insulating gas, the gas would absorb the object's kinetic energy as internal energy.

By exerting force on its surroundings at the expense of its internal energy, a gas that expands adiabatically (without heat transfer) converts internal energy into mechanical energy.

That is undoubtedly the ideal (reversible) process.

Heat cannot be transformed completely into mechanical energy. This is related to the second law of thermodynamics.

And it is because while doing work some of the heat energy has to be expelled to a heat reservoir at low temperature.
