How an object accelerates when it changes direction?

An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes.

Explanation:

An object which experiences either a change in the magnitude.

Explanation:

the direction of the velocity changes.

Hope that helps :)

Have a good day

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

a) the particles of the chair are strongly held together.
