Answer:
Angular displacement before it stops = 18 rev
Explanation:
Given:
Speed of fan w(i) = 6 rev/s
Speed of fan (Slow) ∝ = 1 rev/s
Final speed of fan w(f) = 0 rev/s
Find:
Angular displacement before it stops
Computation:
w(f)² = w(i) + 2∝θ
0² = 6² + 2(1)θ
0 = 36 + 2θ
2θ = -36
Angular displacement before it stops = -36 / 2
θ = -18
Angular displacement before it stops = 18 rev
A the rest of them do not make sense
I don’t know immma gonna guess C
F=ma=kg*m/s^2=N
Work=W=Force*d=N*m
P=W/time=N*m/s=kg*m^2/s^3=kg*m^2*s^-3=Watt
So 1 Watt of Power is equivalent to (kg*m^2)/s^3 or kg*m^2*s^-3
Any questions please feel free to ask. Thank you
Answer:
0.796 degree
Explanation:
We are given that
Wavelength=
We have .to find the angle of the third dark interference minimum=3
Using the formula
Hence, the angle of the third dark interference minimum=0.796 degree
