Explanation:
It is given that,
Wavelength of red light, 
Power of the laser, 
(a) The energy carried by each photon is given by :


(b) Let n is the number of photons emitted by the laser per second. It can be calculated as :


Hence, this is the required solution.
F=m•a(squared)
F=8,000•4(squared)
F=8,000•16
F=128,000
then divide by 2 which is
64,000 Joules
Answer:
The force experienced is 0.6 N
Explanation:
Given data
length of wire L= 2 m
current in wire I= 0.6 A
magnetic field B= 0.5
The force experienced can be represented as


Mass of the vehicle = 2000 kg
Velocity of the vehicle = 90 km/hr
= 25 m/s
Radius of the curve = 80 m
Then
Centripetal force = [2000 * (25)^2]/80
= (2000 * 625)/80
= 15625 kg m/s
= 15625 Newton second
