A girl picks a 0.57 kg book up off the floor and places it on a bookshelf 1 meter above the floor. The book now has 5.6 J of pot
1 answer:
Answer:
Work done to pull the book upwards is 5.6 J
Explanation:
As we know be the relation of work and potential energy that change in gravitational potential energy of the system is equal to the work done on it
so we will have
when book is placed on the ground then its initial potential energy is given as
final position potential energy is given as
now we have

(a)
The radiation pressure exerted by an electromagnetic wave on a surface that totally absorbs the radiation is given by
where
I is the intensity of the wave
c is the speed of light
In this problem,
and substituting , we find the radiation pressure
(b)
Since we know the cross-sectional area of the laser beam:
starting from the radiation pressure found at point (a), we can calculate the force exerted on a tritium atom:
And then, since we know the mass of the atom
we can find the acceleration, by using Newton's second law:
