Answer:

A. Melting point

Explanation

Melting point is the point of temperature at which solid changes it's state to liquid while freezing point is the point of temperature at which liquid changes it's state to solid.

Melting and freezing point of water is same i.e. 0 degree centigrade and at this temperature 80 calories of heat per gram of solid ice will convert it into liquid water.

Summerize how friction and inertia act on an object sliding on a flat surface

natta225 [31]

Inertia is when a object in motion will stay in motion or in a standing still state unless acted upon by a unbalancing force.
Friction is when a object slows down because it is rubbing against another object.

If a object is sliding across a surface, theoretically, it would not stop but because it is on a flat surface it would experience friction, this will disperse some of the kinetic energy that it has thus slowing the object down eventually, after some time, to a stop.

Hope this helps! :)

I push a box with mass 10 kg across a 15 m room. If I apply a force of 20N to do this how much work is being done on the box?

devlian [24]

You could use the formula

W=Fd

F(force)=20N

D(distance/displacement) =15m

W=(20N)(15m)

W= 300 J

Answer:

a. 9.8 m/s2.

Explanation:

The acceleration depends on the force of gravity. It's independent of the velocity of the ball.
