Answer:
θ = 41.80°
Explanation:
Given that
Mach number M= 1.5
We know that
M = u/c
Where c is the velocity of sound and u is the speed of plane
c= 340 m/s
So
u = 1.5 x 340 m/s
u = 510 m/s
We know that
Now by putting the values
θ = 41.80°
So the angle will be 41.80°.
Using the rotational equivalent of force:
Which is T = I*Alpha
Where: T is torque, I is the moment of inertia and Alpha is
the angular acceleration.
This is for the flywheel: J = 1/2mr^2 = 5*3^2 = 45
kgm^2
From the equation:
T = J*dω/dt
we get:
Δt = J*Δω/T = 45*8.13/110.0 = 3.326 sec
Answer:
Explanation:
12 degree = (π / 180) x 12 radian
= .2093 radian
position of third bright fringe = 3λ D/ d where λ is wave length of light , D is screen distance and d is slit separation
given
3λ D/ d = 30 x 10⁻²
angular separation
3λ / d = .2093
from the two equation
.2093 D= 30 x 10⁻²
D = 30 x 10⁻² / .2093
= 1.43 m
