Answer:
0.005556
Explanation:
The period of a typical class at a high school might be 55 minutes; every 55 minutes a class cycle begins (50 minutes for class and 5 minutes for passing time means that a class begins every 55 minutes). The period for the minute hand on a clock is 3600 seconds (60 minutes); it takes the minute hand 3600 seconds to complete one cycle around the clock.
<u>How to get period from frequency</u>
- The formula for the period is T = 1 / f, where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.
- To get period from frequency, first convert frequency from Hertz to 1/s.
- Now divide 1 by the frequency. The result will be time (period) expressed in seconds.
False... I hope that helps ;)
Answer:
v = 0.999981c m/s
Explanation:
Using the time dilation equation

T = stationary time = 100 years
T₀ = 11/12 years = 0.917 years
v = speed of travel in the space = ?
c = speed of light = 3 * 10⁸ m/s


v = 299987395.57 m/s
v = 2.99 * 10⁸ m/s
v = 0.999981c m/s
D. How high do the sound waves go
<u>Answer
</u>
Mechanical energy ⇒ Electric energy
<u>Explanation
</u>
A generator is used to produce electric energy. When he coils are made to rotate/spin, is makes the mechanical part. This coils rotates inside a magnetic fields inducing current in the coils. When current starts flowing in the coils, it forms the electrical part.
So, on the generator the energy changes are from mechanical to electrical energy.
