Where on a roller coaster is centripetal forces at work.

1 answer:

5 0

Regardless of where the cars are in the loop, centripetal force is always directed toward the center of rotation. So even if a car you're riding in is at the top of a loop, upside-down, you will feel pressed into your seat.

Tema [17]

A field is the description of a spatial region, the force exerted on objects by a field is a field force.
gravitational force field: surrounds every material object, although only objects planet-sized or larger exert significant gravity.
electric force field: surrounds and affect electrical charges
magnetic force field: surround magnets and materials with electricity flowing through them. magnetic fields affect susceptible materials such as iron or other magnets.

24. A total of 165 J of work is done on a gaseous refrigerant as it undergoes compression. If the internal energy of the gas inc

Yuliya22 [10]

The total amount of energy transferred as heat is equal to 288 Joules.

<u>Given the following data:</u>

Internal energy = 123 Joules

Work done = 165 Joules

To calculate the total amount of energy transferred as heat, we would apply the first law of thermodynamics.

<h3>The first law of thermodynamics.</h3>

Mathematically, the first law of thermodynamics is given by the formula:

$\Delta E = Q - W$

<u>Where;</u>

$\Delta E$ is the change in internal energy.

Q is the quantity of heat transferred.

W is the work done.

Substituting the given parameters into the formula, we have;

$123 = Q - 165\\\\Q=123+165$

Q = 288 Joules.
