Explanation

• V=f/λ is an expression that holds good for wave velocity
• ***
• The wave velocity of a wave is given by v=fλ 
• ****
• lambda = refers to the wavelength, the distance between the crests in meters (m)
• v = refers to the velocity of the speed of waves moving in a direction in meters per second (m/s)
• f = refers to the frequency, the wave crests that go through a point in certain time cycles per second or hertz (cycles/s or Hz)

• Consider the element helium.
• Its atomic number is 2, so it has two protons in its nucleus.

Similarly, you could input the percentages normally and then divide by $100$:

${\text{M}}_r\left(\text{Ga}\right)=\frac{(68.9256\cdot 60.108)+(70.9247\cdot 39.892)}{100}$

${\text{M}}_r\left(\text{Ga}\right)=69.7231\text{to 4 decimal places}$

Explanation

Uniform circular motion denotes the motion of an object in a circle at a constant speed.

An object moves in a circle constantly changes its direction.

Velocity and acceleration changes but the speed does not change.
