Answer:
The angular acceleration is final angular speed is
Explanation:
Here we know that
.............. 1
Upon substituting these values in equation 1 we get .
For calculating angular velocity we know that
.
Power is the rate of work or energy. It has units of Watts. For an electrical circuit, it can be calculated by multiplying the voltage and the current flowing. Ampere represents the amount of electricity while voltage represents the force of the electricity flowing. We calculate as follows:
P = IV
P = 1 A (5x10^2 V)
P = 5x10^2 W
Of the materials listed wood is the best insulator. It would be the least hot if exposed to similar temperatures.
Answer:
Change its velocity by 10 m/s in 1s
Explanation:
Answer:
To find the total resistance of the circuit:
They are 2 ways to get that ( you can use both methods for 1 exercise)
1- If resistances are series, just add together .
Rt = R1 + R2
2 If are parallel, do the same thing but the inverse of each resistance .
Rt =1/R1 + 1/R2
