from rarefaction to rarefaction for a longitudinal wave
Explanation:
Explanation: When it is at the first point , it doesn't have a proper running force and energy is stored, therefore, potential energy is more. And at forth point, it has a large running force and it has now kinetic energy. And that's why point 1 has greater potential energy than point
<span><u><em>Answer:</em></u>
non-renewable energy resources are the ones that can be used up
<u><em>Explanation:</em></u>
<u>Energy resources can be classified into two categories:</u>
<u>1- non renewable resources:</u> these are the energy resources that cannot renew themselves. They are the resources that are formed from sources that can be consumed and run out. All fossil fuels are considered non renewable resources
Examples of non renewable energy resources: coal, oil, gas, petroleum , ......
<u>2- renewable resources:</u> these are the energy resources that are always present and can easily be renewed. Therefore, they do not come to an end.
Examples of renewable resources: solar energy, wind energy,.....
Based on the above, the energy resource that can be used up is the non renewable energy resource.
Hope this helps :)</span>
Answer:
The time is 
Explanation:
Given that,
Capacitor = 120 μF
Voltage = 150 V
Resistance = 1.8 kΩ
Current = 50 mA
We need to calculate the discharge current
Using formula of discharge current
Put the value into the formula
We need to calculate the time
Using formula of current
Put the value into the formula
Hence, The time is
Answer:
The density is: 
Explanation:
Recall that density is defined as the quotient of the object's mass divided by volume. So, we calculate the volume of the 3 cm side cube:
then the density becomes:
