The data table depicts an object moving with changing speed.
true
false

TRUE

Explanation:

Uniform speed means the object will travel in such a way that it must cover equal distance in equal interval of time.

So after each equal interval of time the distance moved by the object is same then it is uniform speed but if the object travel unequal distance  in equal interval of time then it is representing the changing speed.

So here we can see that object covers 1 m distance in first interval of 1 s while in next 1 s interval from t= 1 to t = 2 it moved total distance of d = 5 - 1 = 4 m

In next interval of 1 s from t = 2 to t =3 it moved total distance of d = 25 - 5 = 20 m

So here we can say that speed of the object is changing

So above statement is TRUE

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
