The question has no answer, sad to say. The symbol W is used as a shortcut of saying "watts" which refers to the unit of power.
The symbol for Voltage = V
The symbol for resistance = R (unit is Ohms)
The symbol of electromagnetic force = N (for Newton)
The symbol or current = I (unit is A for amperes)
Answer:
The wavelength of the incident light is 
400 nm
Explanation:
Given data
Distance between the sits
d = 1.5 × 
m
°
m = 2
We know that the wavelength of the incident light is given by
Put all the value in above formula we get
×
4 × 
m
400 nm
Therefore the wavelength of the incident light is 400 nm
Because gas and liquid are both different things
If the coefficient alpha for a stress scale was computed to be 0.80, the scale would be strongly reliable. A coefficient alpha that is at least 0.70 and above is considered to have a strong internal consistency, which means the items in the scale are closely related as a group.
