The nuclear forces are very short range whereas the electromagnetic force has a long range.
Answer: A
Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
Answer:
The pressure is
Explanation:
From the question we are told that
The initial pressure is
The temperature is
Let the first volume be Then the final volume will be
Generally for a diatomic gas
Here r is the radius of the molecules which is mathematically represented as
Where are the molar specific heat of a gas at constant pressure and the molar specific heat of a gas at constant volume with values
=>
=>
=>
=>
Answer: because the plane of coot is hot
Explanation:
The mass of the electron is Kg.
<h3>How can we calculate the mass of the electron?</h3>
To calculate the mass of the electron we are using the formula,
Here we are given,
=The rest mass of an electron = kg.
v= The velocity of electron = 0. 85c.
c= The velocity of light = c. (c= m/s)
We have to found the mass of an electron = m Kg.
Now we substitute the known values, we found that,
Or,
Or,
Or, Kg.
From the above calculation we can conclude that, The mass of the electron is Kg.
