Answer:
Acceleration =0
Explanation:
There are two forces on the box in horizontal direction.
First one is horizontal component of 30N at 45°.

Another one is given in opposite to direction of motion mean opposite to this force.
Which is = 2.22 N
Now we know F (net) =mass*acceleration(center of mass)
21.2-21.2 =10*acceleration
acceleration =0
Answer:
Force,friction,inertia and momentum
Explanation:
The speed that the marble is moving at can be determined by the amount of force used when pushed or pulled and what kind of surface it's on.Momentum is also a factor because of the mass of the marbles.
Answer:
Rest and Motion are relative terms.
I dotn know sorryyyyyyyyyyy
Elements with low specific heat values tends to absorb heat energy lesser which means it will heat up faster. Having low specific heat values means it can have rapid changes in temperature. Metals generally have a low specific heat capacity, that's why their temperature can change so quickly.
