Answer:
The magnitude of the angular acceleration is 
Explanation:
From the question we are told that
The angular speed of CD is 
time taken to decelerate is 
The final angular speed is 
The angular acceleration is mathematically represented as

substituting values


The negative sign show that the CD is decelerating but the magnitude is

Isaac Newton was experimenting with prisms and discovered that all light is made up of the colors of the rainbow.
The correct answer is A.
Answer:
Resistance, R = 13 ohms
Explanation:
The Ohm's law gives the direct relationship between the voltage, current and the resistance of the device. The relation is as follows :

Where
I is the current
r is the resistance
The value of resistance is given by :

According to given data,
Voltage of the circuit, V = 130 V
Current rating of the circuit, I = 10 A
Resistance of the device,

R = 13 ohms
So, the resistance of the device is 13 ohms. Hence, this is the required solution.
