Explanation:
Scientist and astronomers have observed that large gas clouds and massive stars are orbiting around in an accelerated manner in center of our galaxy that is milky way. A massive star S2's motion has been studied and it is found that the star is revolving around the center of the galaxy. From this scientist have confirmed presence of super massive black hole of 3 million solar masses lurking around the center of milky way.
A graph. This can be called a graph. A graph is the answer.
The wavelengths of radio waves are much LARGER than the wavelength of microwaves. Therefore, radio waves carry much LESS energy than a microwave.
Answer:
At the top of the track right before they are about to go down
Explanation:
Right before he’s about to go down he has potential energy because he is not moving downwards... I think.
Answer:
Part a)
the efficiency will be 100%
Part b)
for above condition internal resistance of the cell must be ZERO
Explanation:
Electric current supplied by the battery is given as
now the total power supplied by the cell is given as
power supplied to external load is given as
Part a)
If output power is adjusted to have maximum value then value of internal resistance must be ZERO
for same condition power given by the cell
so the efficiency will be 100%
Part b)
for above condition internal resistance of the cell must be ZERO
