Rank the objects below from least to greatest momentum:

A car travelling down the highway
A book falling from a table
A butterfly flying through the air
The school building

The correct order of momentum from least to greatest is given as

School building < Butter fly < Book falling from table < Car travelling on highway

Explanation:

As we know that the momentum is defined as the product of mass and velocity

Here we have to compare the momentum of objects by the mass and velocity both

A car travelling down the highway

A book falling from a table

A butterfly flying through the air

The school building

out of above all car is heavy as well as moving with high speed on highway so it will have maximum momentum, then school building is heavy in mass but its speed is zero so its momentum is minimum and least

Then out of butter fly and the book the book is much heavy than butter fly so momentum of book is more than butter fly

So here correct order is

School building < Butter fly < Book falling from table < Car travelling on highway

the ima (higher than 1m) will be greater than the ima with the height of 1m.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
