By definition, the power is equal to the product of the current high squared by the value of the resistance.
 In other words:
 P = I ^ 2 * R
 where,
 I: Current
 R: resistance
 If we double the resistance in a circuit but keep the current in it constant, then:
 P = (I ^ 2) * (2 * R)
 P = 2 * (I ^ 2 * R)
 The power increases twice.
 answer:
 The power dissipated by that circuit will increase twice

A tub of water is placed in a small room and heat is removed from the room. What will most likely occur if enough heat is remove
NARA [144]

Answer:

(A)The water will freeze.

Explanation:

Heat is the energy that when transferred causes change in temperature. If heat is added to a body by some process the bodies temperature increases and if heat is removed from a body by some process the temperature reduces.

In this case if enough heat is removed from the room the internal movement of the water particles will slow down causing the water to form crystal lattice thus forming ice. So, the water will freeze.

What did physicist James Joule's famous paddle wheel experiment demonstrate?
PilotLPTM [1.2K]

<u>Answer </u>

A. that the initial gravitational potential energy of the masses transformed into kinetic energy of the paddles and then to thermal energy in the water


<u>Explanation</u>

James Joule allowed some water to fall from a height of 1 foot. the water would turn a paddle wheel at the bottom causing a temperature of water to raise.

The height form which the water fell, mass and the temperature of water was measured and used to calculate mechanical equivalent of heat.

From the choices given the best answer is A. that the initial gravitational potential energy of the masses transformed into kinetic energy of the paddles and then to thermal energy in the water.

Does the area of contact effect the frictional force . explain?​
OlgaM077 [116]

Answer:

The force due to friction is generally independent of the contact area between the two surfaces. This means that even if you have two heavy objects of the same mass, where one is half as long and twice as high as the other one, they still experience the same frictional force when you drag them over the ground.
