Answer:
4.8 watts
Explanation:
power = voltage * current = 12.0 * 0.40 = 4.8 watts
A, emits light. Go to a shop with a neon light, it'll always glow (the light, not the shop)
Answer:
Option A
Explanation:
An Uninterruptible Power Supply abbreviated as UPS is used in case of the failure of the power mains or the input power in order to ensure uninterrupted power supply.
The Ac voltage is first converted to DC and then again inverted to the AC and is fed to the system.
Thus if the UPS malfunctions then in order to check the output using multimeter we use AC voltage setting because the UPS purely supplies AC power, even if the power is supplied from its internal battery then also it inverts the DC into AC and then supply.
The linear velocity of the wheel is 16 m/s.
<h3 /><h3>What is linear velocity?</h3>
Linear velocity is the rate of change of displacement with regard to time when the object is moving in a straight line
To calculate the linear velocity of the wheel, we use the formula below.
Formula:
- v = ωr............. Equation 1
Where:
- v = Linear velocity
- ω = Angular velocity
- r = Radius of the wheel.
From the question,
Given:
Substitute these values into equation 1
Hence, The linear velocity of the wheel is 16 m/s.
