Answer:
when the pencil is balanced on a point it is motionless due to net force only acting trough the center, but when we release the position we are changing the location of a pencil hence due to turning affect it will expericence torque and the angular acceleration produced.
for the complete answer the length and mass of pencil should be known i am giving the general expression for the calculation of angular acceleration
Explanation:
<h3>τ=Iα</h3><h3>τ= torque</h3><h3>I = inertia</h3><h3>α= angular acceleration</h3>
where
I= mL^2/3 (by geometry of pencil)
when the pencil is released it will experience force due to weight
F=mgsinθ
so τ=Fxd
τ=mgsin(10°)x(L/2)
then.
α=τ/I
α=mgsin(10°)xL/2÷(mL^2)/3
Answer: 13062.5 N
What average force is required to stop an 1100-kg car in 8.0 s if it is traveling at 95 km/h? i got the answer to be 13062.
Answer:
electrical 'pressure' measurement
Explanation:
An insulator does not have electrons that are free to move, and a conductor does.
The equation to work out acceleration would be the final velocity subtract the start velocity divided by the time. So... in order to answer the question we would need the time taken.
