Acceleration = (change in speed) / (time for the change)
Change in speed = (New speed) - (old speed)
Change in speed = (0.8 m/s - 0.5 m/s) = 0.3 m/s
Time for the change = 3 seconds
Acceleration = (0.3 m/s) / (3 s)
<em>Acceleration = 0.1 m/s²</em>

Answer:
A. Generator
Explanation:
An alternator which is also called a generator basically converts mechanical energy into electric energy.
An alternator is used in a vehicle to charge the battery. It supplies electric power to the automobile.It is attached to the engine and is driven by a belt system . When the alternator does not charge the battery, it can be understood that it is not working as it no longer recharges the battery, though the engine of the automobile runs.
Answer:
Explanation:
Given that
Wavelength
slit separation
slit screen distance
We know that for double slit the maxima condition is that
For small angle approximation,
Now
Again
Hence
The amount of electrical energy used by the television is given by:
where P is the power of the device and t is the time.
The power of the television is P=315 W, while the total time is
If we substitute these numbers into the formula, we find the energy:
so, the correct answer is
(1) 5.67 × 10^5 J
