( Apply Concepts ) Nome , Alaska, lies at 64°N latitude. San Diego , California , lies at 32°N latitude. Which city receives mor
tatyana61 [14]
If your asking about the total amount of time the sun is visible, it will be equal over the course of a year. In Nome, Alaska, it will be daylight almost 24 hours a day in the summer and be dark almost 24 hours a day in the winter. In San Diego they are much closer to the equator and will receive sunlight roughly the same amount each day all year long. In the end these times will add up to the same amount.

However if you are asking about intensity of sun light received, San Diego will get considerably more since its near the equator and its getting almost direct sunlight. In Nome, the sunlight is hitting the earth at an angle so fewer rays of light are hitting the ground per square foot.

The kinetic energy of a rotating body is generally written as K=12Iω2, where I is the moment of inertia. Find the moment of iner
stira [4]

Answer:

See explanation

Explanation:

We have a mass m revolving around an axis with an angular speed \omega, the distance from the axis is r. We are given:

\omega = 10 [rad/s]\\r=0.5 [m]\\m=13[Kg]

and also the formula which states that the kinetic rotational energy of a body is:

K =\frac{1}{2}I\omega^2.

Now we use the kinetic energy formula

K =\frac{1}{2}mv^2

where v is the tangential velocity of the particle. Tangential velocity is related to angular velocity by:

v=\omega r

After replacing in the previous equation we get:

K =\frac{1}{2}m(\omega r)^2

now we have the following:

K =\frac{1}{2}m(\omega r)^2 =\frac{1}{2}Iw^2

therefore:

mr^2=I

then the moment of inertia will be:

I = 13*(0.5)^2=3.25 [Kg*m^2]
