Chegg A uniform solid disk of mass m = 3.01 kg and radius r = 0.200 m rotates about a fixed axis perpendicular to its face with
ipn [44]

Answer with Explanation:

We are given that

Mass=3.01 kg

Radius,r=0.2 m

Angular frequency,\omega=5.97 rad/s

a.Angular momentum,L=I\omega=\frac{1}{2}mr^2\omega=\frac{1}{2}(3.01)(0.2)^2(5.97)=0.36 kgm^2/s

b.When the axis of rotation passes through a point midway between the ceneter and rim then moment of inertia,I=\frac{3}{4}mr^2

Angular momentum,L=\frac{3}{4}(3.01)(0.2)^2(5.97)=0.55 kgm^2/s

A cylinder that is 20 cm tall is filled with water. If a hole is made in the side of the cylinder 5 cm below the top level, how
lara31 [8.8K]

Answer:

See description

Explanation:

This is an example where we need Tornicelli's law, which states that the horizontal speed of a fluid that starts falling from an orifice is the same speed that an object acquires from free-falling.

v = \sqrt{2gh}

we are given:

h_{cilinder} = 0.2 [m]\\h = 0.05 [m]\\d=0.15[m]

the horizontal velocity of the water at the start is:

v = \sqrt{2(9.8)(0.05)}=0.989949 [m/s]=1[m/s]

now we need to find the time for the water drops to fall d:

as the gravity is the only force interacting with the water we have:

y(t) = \frac{1}{2} g*t^2

replace for y = d

0.15 = \frac{1}{2} g*t^2=>t=\sqrt{\frac{2*0.15}{9.8}}=0.1749[s]

now that we have t we notice that there are no horizontal forces interacting with the water, so the horizontal position is given by:

x(t)=v*t

Finally, we replace v and t:

x(2.45) = 1*0.1749 = 0.1749 [m]=17.49[cm]

Why does the frequency of a siren get higher as an ambulance using that siren gets closer
Nadya [2.5K]
The frequency of a wave becomes higher due to the object moving at a fast pace coming towards you with shorter wavelengths  (depending on the speed) aka the Doppler Effect. 
Hope this helps
