We wrap a light, nonstretching cable around a 8.00 kg solid cylinder with diameter of 30.0 cm. The cylinder rotates with negligi

antoniya [11.8K]

Answer:

h = 16.67m

Explanation:

If the kinetic energy of the cylinder is 510J:

$Kc=510=1/2*Ic*\omega c^2$

$\omega c=\sqrt{510*2/Ic}$

Where the inertia is given by:

$Ic=1/2*m_c*R_c^2=1/2*(8)*(0.15)^2=0.0225kg.m^2$

Replacing this value:

$\omega c=106.46rad/s$

Speed of the block will therefore be:

$V_b=\omega_c*R_c=106.46*0.15=15.969m/s$

By conservation of energy:

Eo = Ef

Eo = 0

$Ef = 510+1/2*m_b*V_b^2-m_b*g*h$

So,

$0 = 510+1/2*m_b*V_b^2-m_b*g*h$

Solving for h we get:

h=16.67m

PLEASE HELP ASAP!!!!!

While falling, both the sheet of paper and the paper ball experience air resistance. But the surface area of the sheet is much more than that of the spherical ball. And air resistance varies directly with surface area. Hence the sheet experiences more air resistance than the ball and it falls more slowly than the paper ball.

Hope that helps!

The ratio of the speed of light in a medium to the speed of light in a vacuum

Liula [17]

Answer:D.Refractive Indez

Explanation:

It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".

2. For each pair of variables, identify which is the independent and which is the dependent variable. a. How much gas is left in

Korvikt [17]

For each pair Independent variable and the dependent variable is -

a. How much gas is left in the gas tank vs. how far the car has traveled.

Independent variable = how far the car has traveled

dependent variable = How much gas is left in the gas tank

b. How much money you've spent vs. how much money is in your wallet.

Independent variable = How much money you've spent

dependent variable = how much money is in your wallet.

c. How far a toy car traveled vs. how much time went by

Independent variable = how much time went by

dependent variable = How far a toy car traveled

An independent variable in any experiment or research is a variable that is manipulated or changed in the experiment, this change leads to a direct effect on the dependent variable.

A dependent variable is a variable that is directly affected by the independent variable and it is the variable that is measured or tested in an experiment.

Thus,

a. How much gas is left in the gas tank vs. how far the car has traveled.

Independent variable = how far the car has traveled

dependent variable = How much gas is left in the gas tank

b. How much money you've spent vs. how much money is in your wallet.

Independent variable = How much money you've spent

dependent variable = how much money is in your wallet.

c. How far a toy car traveled vs. how much time went by

Independent variable = how much time went by

dependent variable = How far a toy car traveled
