Answer:
8.0 rad/s
Explanation:
I₁ = 1.0 kgm², ω₁ = -20.0 rad/s (clockwise is positive direction)
I₂ = 4.0 kgm², ω₂ = 15.0 rad/s
Angular momentum conservation:
I₁ω₁ + I₂ω₂ = (I₁ + I₂)ω
1.0 x (-20.0) + 4.0 * 15.0 = (1.0 + 4.0)ω
40.0 = 5.0ω
so ω = 8.0 rad/s
Answer:
A
Explanation:
Wattage = E * I
E = 25
I = 5
Wattage = 25 * 5
Wattage = 125
The secondary, in an ideal transformer has the same wattage.
125 = 50 * I Divide by 50
125/50 = I
I = 2.5
Answer:
Explanation:
<u>Given:</u>
- = uniform electric field in the space =
- Q = Charge placed in the region =
<u>Assume:</u>
- = Electric force on the charge due to electric field
We know that the electric field is the electric force applied on a unit positive charge i.e.,
This means the electric force applied on this additional charge placed in the field is given by:
From the above expression of force, we have the following y-component of force on this additional charge.
Hence, the y-component of the electric force on the this charge is .
The moving of something from its place or position.
"vertical displacement of the shoreline"
the removal of someone or something by someone or something else that takes their place.
"males may be able to resist displacement by other males"
<h2>
Answer:</h2>
He saves 13.2 minutes
<h2>
Explanation:</h2>
Hey! The question is incomplete, but it can be found on the internet. The question is:
How many minutes did he save?
Let's call:
We know that the 135 miles are on the interstate highway where the speed limit is 65 mph. From this, we can calculate the time it takes to drive on this highway. Assuming Richard maintains constant the speed:
Today he is running late and decides to take his chances by driving at 73 mph, so the new time it takes to take the trip is:
So he saves the time :
In minutes:
