Answer 1

Answer:

केज

Step-by-step explanation:

Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.

Answer 2

$( {a}^{2} + {b}^{2} )( { - a}^{2} + {b}^{2})$

rearrange the terms

$( {b}^{2} + {a}^{2} )( {b}^{2} - {a}^{2} )$

apply (b+a)(b-a) =

${b}^{2} - {a}^{2}$

$( { {b}^{2} })^{2} - ( { {a}^{2} })^{2}$

evaluat the exponents:

${b}^{4} - {a}^{4}$
