Answer:
yes it does
Explanation:
Going by the law of conservation of momentum, when two objects collides, the momentum of one object is transferred to the other object.
This collision can be elastic or inelastic coliision
let the mass of the brick be m1
the mass of the cart be m2
the velocity (initial and final) of the brick u1 and v1
the velocity (initial and final) of the cart u2 and v2
For elastic collision
m1u1+m2u2= m1v1+m2v2
For inelastic collision the two bodies will move with the same velocity after impact
m1u1+m2u2=(m1+m2)V
I think its C or D.
Einstein's Nobel winning photoelectric equation.
The higher the work function, the more energy needed to photoeject an electron from the surfface
Try D
Answer:
104 N
Explanation:
m = 1300 kg
a = 0.08m/s^2
F = 1300*0.08
F = 104 N
