An unbalanced net force must be applied .option B.hope it helps plz mark as brainliest
Answer:
v = R w
With this expression we see that for each point at different radius the tangential velocity is different
Explanation:
They indicate that the angular velocity is constant, that is
w = dθ / dt
Where θ is the radius swept angle and t the time taken.
The tangential velocity is linear or
v = dx / dt
Where x is the distance traveled in time (t)
In the definition of radians
θ = s / R
Where s is the arc traveled and R the radius vector from the pivot point, if the angle is small the arc (s) and the length (x) are almost equal
θ = x / R
We substitute in the speed equation
v = d (θ R) / dt
The radius is a constant for each point
v = R dθ / dt
v = R w
With this expression we see that for each point at different radius the tangential velocity is different
Answer:
0.38°
Explanation:
= Angle
m = Number
d = Distance
n = Refractive index of liquid = 1.25
a denotes air
l denotes liquid
In the case of double split interferance we have the relation
For air
For liquid
Dividing the two equations
Wavelength ratio = 
The angular separation is 0.38°
