Answer:
2 seconds
Explanation:
The frequency of a wave is related to its wavelength and speed by the equation
![f=\frac{v}{\lambda}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bv%7D%7B%5Clambda%7D)
where
f is the frequency
v is the speed of the wave
is the wavelength
For the wave in this problem,
v = 2 m/s
![\lambda=8 m](https://tex.z-dn.net/?f=%5Clambda%3D8%20m)
So the frequency is
![f=\frac{2}{8}=0.25 Hz](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B2%7D%7B8%7D%3D0.25%20Hz)
The period of a wave is equal to the reciprocal of the frequency, so for this wave:
![T=\frac{1}{f}=\frac{1}{0.25}=4 s](https://tex.z-dn.net/?f=T%3D%5Cfrac%7B1%7D%7Bf%7D%3D%5Cfrac%7B1%7D%7B0.25%7D%3D4%20s)
This means that the wave takes 4 seconds to complete one full cycle.
Therefore, the time taken for the wave to go from a point with displacement +A to a point with displacement -A is half the period, therefore for this wave:
![t=\frac{T}{2}=\frac{4}{2}=2 s](https://tex.z-dn.net/?f=t%3D%5Cfrac%7BT%7D%7B2%7D%3D%5Cfrac%7B4%7D%7B2%7D%3D2%20s)
Can you post a picture of the whole thing please
Answer: Energy consumption and sustainability is important so that it remain available for future generation.
Explanation:
1. The home furnaces are likely to require fuel like coal, which will directly emit carbon dioxide and carbon monoxide gases. These should be replaced with the electrical furnaces. The old or more power consuming air conditioners should be replaced with new ones.
2. The water heaters should be tankless so their capacity to heat more water could be possible. The water heaters should be electricity saving.
3. Washer and dryers should be water savy and electricity savy. A front-loading washing machine is useful energy saver.
4. The LED lights are more electricity saving than conventional bulbs. Halogen lights are also electricity saving.
Around 8 hours and 20 minutes
Explanation:
I divided 500 by 60 and got 8.3333333333 and i round it up to 8.20, so it is 8 hours and 20 minutes.
Answer:
Answer in explanation.
Explanation:
<u>GRAVITY AS CENTRIPETAL FORCE</u>:
When a satellite orbits around a planet, it is in a circular motion. In this scenario, the centripetal force is provided by the gravity force.
<u>NORMAL FORCE AS CENTRIPETAL FORCE</u>:
When a spacecraft is sent into space, it rotates about its own axis to create artificial gravity. During this rotating motion, the centripetal force is provided by the normal reaction (force) of the walls of the satellite.
<u>TENSION AS CENTRIPETAL FORCE</u>:
When a mass attached to a rope is swirled in a circular motion, the tension in rope acts as the centripetal force.
