A, Lenz' Law. There need to be a difference of flux, so if you use AC you will get a current too.
I would say friction because it requires to surfaces in order for the force to take place
correct me if I'm wrong.
Answer:
A pair of oxygen atoms is a molecule of oxygen. A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms.
Explanation:
Answer:
v = 3.04 m/s
Explanation:
given,
mass of the block, M = 6.6 Kg
horizontal force, F = 12.2 N
distance, L = 2.5 m
initial speed = 0 m/s
speed of the block,v = ?
we now
Work done is equal to change in Kinetic energy.
Work done = Force x displacement
W = Δ K E
Δ K E = Force x displacement
![\dfrac{1}{2}mv^2 - \dfrac{1}{2}mu^2= F .s](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7Dmv%5E2%20-%20%5Cdfrac%7B1%7D%7B2%7Dmu%5E2%3D%20F%20.s)
![\dfrac{1}{2}\times 6.6 \times v^2 - 0= 12.2\times 2.5](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%206.6%20%5Ctimes%20v%5E2%20-%200%3D%2012.2%5Ctimes%202.5)
3.3 v² = 30.5
v² = 9.242
v = 3.04 m/s
speed of the block is equal to 3.04 m/s
