Answer:
Becomes greater
Explanation:
Distance between the central maxima and the next line increase with the wavelength i.e.
As, the wavelength of the red light is greater than the wavelength of the green light, thus, the distance between the central maxima and the next line becomes greater.
Option 5 is correct.
Answer:
The normal force experienced by the car is approximately 8223.2 N
Explanation:
The question relates to banking of road where the centripetal force for the circular motion of the vehicle is provided by the horizontal component of the normal reaction
The mass of the vehicle that moves around the curve, m = 900 kg
The incline of the curve, θ = 20°
The speed with which the vehicle moves around the curve, v = 12.5 m/s
The radius of the curve, R = 50 meters
We have;
Where;
θ = The angle of inclination of the road = 20°
N = The normal force experienced by the car
m = The mass of the car = 900 kg
v = The velocity with which the car is moving = 12.5 m/s
R = The radius of the curve around which the vehicle moves = 50 m
The normal force experienced by the car = N ≈ 8223.2 N.
