Answer:
5.6 volts
Explanation:
According to Ohm's Law, V = IR
where V = voltage, I = Current and R = resistance
Answer:
<em>n =1.33 revolutions</em>
Explanation:
<u>Uniform Circular Motion</u>
The angular speed can be calculated in two different ways:

Where:
v = tangential speed
r = radius of the circle described by the rotating object
Also:

Where:
f = frequency
Solving for f:

Since the frequency is calculated when the number of revolutions n and the time t are known:

We can solve for n:
n=f.t
The particle moves in a circle of r=90 m with a speed v=25 m/s. Thus the angular speed is:


Now we calculate f:


Calculating the number of revolutions:
n = 0.04421*30
n =1.33 revolutions
The correct answer would be a molecule
Answer:
Explanation:
I am sorry but I am not able to see the question
<span>The earth as a whole rotates with a fixed angular velocity. Therefore, you
need to be at the rotation axis to have the smallest tangential speed. This
would be at the north or south pole.</span>
