1 answer:

5 0

The answer is A. Or the first option. Pressure is changed by lowering the pressure, not reducing the volume. You would assume its C but its A.

Consider the case in which the clay is launched along Path Y. The sphere of clay is launched with an initial velocity of v0 and

Helen [10]

Answer:

w = $\frac{m}{ml^2 + I R^2 }$ v l

Explanation:

Let's form a system formed by the clay sphere and the rod, in this case the angular momentum is conserved

initial instant. Before the crash

L₀ = m v l

Final moment. After the collision with the clay stuck to the rod

L_f = I_{total} w

angular momentum is conserved

L₀ = L_f

m v l = I_total w

w = $\frac{m}{I_{total} }$ v l

the total moment of inertia is the sum of the moments of inertia of the two bodies

the moment of inertia of the rod is

I_rod = I R²

I_total = m l² + IR²

we substitute

w = $\frac{m}{ml^2 + I R^2 }$ v l

A 6.50 meter high cylinder is filled with alcohol(density =806 kg/m^3). What is the pressure at the bottom of the cylinder?

makvit [3.9K]

Answer:

152642.2

Explanation:

the pressure at the bottom of the cylinder is

P = Po + rho gh

=101300+806(9.8)(6.5)

=152642.2 Pa
