You’re using more force to kick the brick than to push it gently.
Is the most intensely studied celestial feature. It has also help revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. It is also the closest large star-forming region to Earth. The Orion Nebula is an enormous cloud of gas and dust, is located in our galaxy (Milky Way).
Answer:
A
Explanation:
take note that v=d/t (velocity is distance over(divided by) time, so in this case it would be 200 (distance) divided by 2 (time)
Answer:
Refraction
Explanation:
A pencil bends when it enters the water media due to the phenomenon of refraction.
- Refraction is one of the properties of waves.
- Refraction of light occurs which it crosses from a region having different density values.
- Water is denser than air.
- As light moves from air to wave it becomes refracted
Answer:
frequency = 0.5 Hz and speed = 2 m/s
Explanation:
Given that,
The period of a wave, T = 2 s
Wavelength, 
If f be the frequency. So,
f = 1/T
Speed of a wave is given by :
So, the frequency of the wave is 0.5 Hz and speed is 2 m/s.
