Answer:
Explanation:
Heat gained by ice in warming up to 0⁰C = .035 x 2090 x (83-0)= 6071.45 J
heat used up by ice to melt at 0⁰C = .035 x 3.33 x 10⁵ J = 11655 J
Heat used up in warming up water to t⁰C = .035 x 4186 x t = 146.51 t
heat released by warm water to cool from 22⁰C to t = .565 x 4186 x ( 22 - t )
=52032 -2365.1 t
heat released by copper calorimeter to cool from 22⁰C to t = .087 x 387 x ( 22 - t ) = 740.72 - 33.7 t
total heat released = 52032 -2365.1 t + 740.72 - 33.7 t
= 52772.72 - 2398.8 t
Heat lost = heat gained
52772.72 J- 2398.8 t = 6071.45 J + 11655 J + 146.51 t
2545.31 t = 35046.27
t = 13.8°C.
The sun can transmit heat to earth only by radiation because t<span>he space between the sun and Earth contains almost no matter. The correct option among all the options that are given in the question is the first option. I hope that this answer has come to your great help.</span>
The answer is:
3) a hockey puck moving at constant velocity across ice.
The explanation:
when the Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.
- A force which is not opposed by a force of equal magnitude and acting in the exact opposite direction hence leading to the motion of the object is called an unbalanced force.
- The forces which speed up slow down the objects or makes them change their direction are called Unbalanced forces.
and the phase which satisfy this definition is (3)
