Answer:
820 nm
Explanation:
We are given that
Wavelength=
For first minimum therefore
m=0
We know that for destructive interference
Substitute the values
Hence, the distance between two slits that produces the first minimum=820 nm
Answer:
The velocity is 40 ft/sec.
Explanation:
Given that,
Force = 3200 lb
Angle = 30°
Speed = 64 ft/s
The resistive force with magnitude proportional to the square of the speed,
Where, k = 1 lb s²/ft²
We need to calculate the velocity
Using balance equation
Put the value into the formula
Put the value of k
At terminal velocity
So,
Hence, The velocity is 40 ft/sec.
