Answer:
Pluto revolves around sun with constant speed in a circular orbit, so it is an example of uniform circular motion.
Answer:
The wave moves away from the normal
Explanation:
Waves are the disturbances that are able to carry energy from one place to another. These waves can travel in both the denser as well as the rarer medium.
In the denser medium, the waves travel at a slower rate, and on the other hand, in rarer medium, the waves can travel at a comparatively faster rate.
As a wave moves from a layer of low velocity (denser medium such as a liquid) to a layer of high velocity (rarer medium like air), then the waves move away from the normal (perpendicular line) and result in the increase in the velocity of the wave.
Answer:
They move farther apart
Explanation:
When objects heat up they expand for example heating up a balloon makes it expand
To solve this problem we will apply the concepts related to Ohm's law and Electric Power. By Ohm's law we know that resistance is equivalent to,
Here,
V = Voltage
I = Current
While the power is equivalent to the product between the current and the voltage, thus solving for the current we have,
Applying Ohm's law
Therefore the equivalent resistance of the light string is
