supply it with more energy. one way to do is to produce vibrations in the same frequency as the wave. This would cause resonance leading to higher amplitude
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world.
Answer:
By Factor of 4
Explanation:
The expression for centripetal acceleration is given as,
a = v²/r........... equation 1
Where a = centripetal acceleration, v = speed, r = radius of the circle.
Case 1
Given: v = 150 m/s, r = 500 m
Substitute into equation 1
a = 150²/500
a = 22500/500
a = 45 m/s².
Case 2
Given: v = 300 m/s, r = 500 m
Also substitute into equation 1
a = 300²/500
a = 180 m/s²
Factor of change of the acceleration = 180/45
Factor of change of the acceleration = 4.
Hence the acceleration will change by a factor of 4
Answer:
Part a)
charge through the battery is
Part b)
Maximum current is
i = 386 A
Explanation:
Part a)
As we know that the rating of battery is given as
here we also know that the charge given by the battery is same as the capacity of the battery
so we will have
Part b)
Now we know that current in the wire is given by
now plug in all values in it
