Based on the sped of the waves and the tension as well as the needed wave speed, the required tension is 13.5 N.
<h3>What is the required tension?</h3>
Given the initial tension and speed, the tension that is required can be found by the formula:
= Initial tension x (Required speed / Initial speed)²
Solving gives:
= 6 x (30 / 20)²
= 6 x 9/4
= 13.5 N
In conclusion, the tension required is 13.5N.

Answer:
Equal number of protons and electrons
Explanation:
This principle of proton and electron equality was used by J.J. Thompson in the discovery of proton. After he had discovered the electron. He discovered that since atoms are electrically neutral, that means there must be equal number of protons to balance out the electrons present in the atom.
Answer:
When the pressure and the temperature are increased the volume is 285.7 ml.
Explanation:
We can find the new volume by using the Ideal Gas Law:
Where:
P: is the pressure
V: is the volume
n: is the number of moles
R: is the gas constant
T: is the temperature
Initially, when V₁ = 200 ml, P₁ = 500 torr and T₁ = 10 °C, we have:
(1)
And finally, when P₂ = 700 torr and T₂ = 20 °C, we have:
(2)
By equating (1) with (2):
Therefore, when the pressure and the temperature are increased the volume is 285.7 ml.
