Answer 1

${\tt{\red{\underline{\underline{\huge{Answer:}}}}}}$

$\longrightarrow$ The rate of change of velocity per unit time is called acceleration.

$\longrightarrow$ Its SI unit is m/s².

Answer 2

we have that from the Question"Which of the following is the cause of an acceleration?" it can be said that  

• Acceleration cause bodies to move at an increasing rate after which a velocity or speed is maintained

• Force is a main cause of Acceleration and

• acceleration is seen at a change in velocity

From the Question we are told

Which of the following is the cause of an acceleration?

Generally the equation for acceleration is mathematically given as

$a=\frac{F}{m}\\\\or\\\\a=\frac{u-v}{dt}$

Therefore

• Acceleration cause bodies to move at an increasing rate after with a velocity or speed is maintained

• Force is a main cause of Acceleration and

• acceleration is seen at a change in velocity

So in the selection of the option consider these points of acceleration

• Acceleration cause bodies to move at an increasing rate after which a velocity or speed is maintained

• Force is a main cause of Acceleration and

• acceleration is seen at a change in velocity
