Answer:
it's can be detected only through the use of thermal imaging e
Answer:
F= 12 N
Explanation:
Given that
Work done by student ,W= 60 J
The mass of the box ,m = 3 kg
Length ,x = 5 m
We know that ,The work done by a force a force F is given as
W= F .x
x=Displacement
F=Force
W=Work
Now by putting the values
60 = F x 5
F= 12 N
That is why the magnitude of the force will be 12 N.
Distance of a fall from rest = (1/2) (gravity) (time)²
= (4.9 m/s²) (12.5 sec)²
= (4.9 · 12.5²) m-sec² / sec²
= 766 meters (rounded)
Quite a high cliff !
It can't be destroyed or created, and in a closed system the energy is conserved.
I hope this helped!
