Answer:
They will both bounce back at the same speed they had before the collision
Explanation:
Assuming an elastic collision, kinetic energy will be conserved. Therefore, the billiard balls will have the same speed after the collision as before the collision.
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:
Fb = 941.76 [N]
Explanation:
La fuerza de flotacion se define como el producto de la densidad del liquido por la aceleración gravitacional y por el volumen desplazado
Fb = Ro*g*V
donde:
Fb = fuerza de flotacion [N] (unidades del Newtons)
Ro = densidad del liquido = 1000 [kg/m³]
g = aceleracion gravitacional = 9.81 [m/s²]
V = volumen desplazado = 0.096 [m³]
Reemplazando:
Fb = 1000*9.81*0.096
Fb = 941.76 [N]
