Answer:
The source of light and the phenomenon of reflection are responsible for an object to be seen
Explanation:
Answer:
Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.
Answer:
The kinetic energy of the clam at a height of 5.0 m is 5.19 J and the speed of the clam at that height is 9.71 m/s.
<u>Explanation:
</u>
<em>Mechanical energy is constant throughout the travel</em>, we know that <em>mechanical energy is calculated by adding potential energy and kinetic energy</em>. Potential energy = ,
Kinetic energy = and Mechanical energy = Kinetic energy is zero at initial point. Now mechanical energy of clam with m=0.11kg,g=9.81,h=9.8 m is = 0.11×9.81×9.8 = 10.58 J.
Mechanical energy of clam at a height of 5.0 m = =. We know that mechanical energy is constant hence, <em>mechanical energy of clam at height 9.8 m is equal to mechanical energy at height 5.0 m</em>. This is represented as following
10.58 = 10.58 – 5.39 = 5.19 = kinetic energy of the clam is 5.19 J.
Now speed of the clam at height 5.0 m is 5.19 = 94.36 = = 9.71 m/s. The speed of the clam is 9.71 m/s.
An object in motion will stay in motion unless acted upon another force.
Newton used this to prove that gravity existed. Without an unseen force, we could throw a ball and it would go on forever correct? Unless there was something to pull it down, in this case, gravity.
The pressure will increase
