Mass and velocity that is your answer
Answer:
The magnitude of the angular acceleration is α = (3 * F)/(M * L)
Explanation:
using the equation of torque to the bar on the pivot, we have to:
τ = I * α, where
I = moment of inertia
α = angular acceleration
τ = torque
The moment of inertia is equal to:
I = (M * L^2)/3
Also torque is equal to:
τ = F * L
Replacing:
I * α = F * L
α = (F * L)/I = (F * L)/((M * L^2)/3) = (3 * F)/(M * L)
Answer:
it will have a stronger attraction force
Explanation:
The direction of the friction force is the same than the movement, but its sense is the opposite.
cation
anion is negatively charged, so more electrons then protons,
cation is positively charged, so more protons thatn electrons
