This is a diagram from above, the air resistance is oppose to movement, the bird is moving forward given its force is bigger.
Answer
Given,
Time to hear the clap = 14.4 s
speed of the light = 3 x 10⁸ m/s
Speed of sound = 343 m/s
a) distance where lightning strike
D = s x t
D = 14.4 x 343
D = 4939.2 m
b) No, we do not need to know the value of speed of light. Because we need to calculate the distance where we hear the sound. To calculate that we need to know the speed of sound.
Answer:
Troposphere, stratosphere, mesosphere and thermosphere. The next region is the exosphere, but that region is 500+ km from the Earth's surface.
<h3>Answer:</h3>
the dishes and silverware are in inertia of rest
<h3>Explanation:</h3>
Newton's first law of motion is that things at rest tend to stay at rest unless acted upon by an external force.
A silk tablecloth will have a fairly slippery surface, so there is not much friction to cause tableware to be accelerated.
Government should continue to fund fusion energy research because:
- it potentially will produce large amounts of energy
- scientific research could discover more feasible methods of fusion energy production
- it is a very clean form of energy
<h3>What is fusion energy?</h3>
Fusion energy is the energy produced from fusion reactions.
Fusion reactions are a type of nuclear reaction in which small atomic nucleus are fused together to produce larger atomic nucleus with the release of large amounts of energy.
The Sun produces its energy from fusion reactions between hydrogen atoms to produce helium nucleus. This reaction takes place at very high temperatures.
It is important that the government continue to fund fusion energy research because:
- it potentially will produce large amounts of energy
- more scientific research could discover alternative cheaper methods of fusion
- it is a very clean form of energy
In conclusion, the continuous government funding will make it possible to finally discover cheaper and more feasible ways to produce fusion energy.
