Because its so far, and the only telescope we had to see the planets stopped working.
Answer:
First statement: The particles which are displaced is parallel to the direction of energy transport or to the direction the wave travels.
Second statement: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position.
Third statement: wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Explanation:
Wave can be defined as a displacement that occurs in a medium, from one point to another. There are two different kinds of waves in physics which includes:
- Longitudinal wave and
- Transverse wave.
In a longitudinal wave, particles are displaced parallel to the direction of energy transport or to the direction the wave travels. There are also different properties which can be used to describe a longitudinal wave and they includes:
- amplitude: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position in a longitudinal wave.
- wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.
Answer:
As an object’s temperature increases, the Rate at which it radiates energy increases.
Answer: I never said anything to them but if i did it would be "I need a break from you, i love you but sometimes I have to find the path on my own." i would say this if i wasn't scared to hurt them.
Explanation:
Answer:
the speed of the tip of a blade 10 s after the fan is turned off is 16.889 m/s.
Explanation:
Given;
diameter of the ceiling fan, d = 90 cm = 0.9 m
angular speed of the fan, ω = 64 rpm
time taken for the fan to stop, t = 28 s
The distance traveled by the ceiling fan when it comes to a stop is calculated as;
The speed of the tip of a blade 10 s after the fan is turned off is calculated as;
Therefore, the speed of the tip of a blade 10 s after the fan is turned off is 16.889 m/s.
