Answer:
This is because when the pedal sprocket arms are in the horizontal position, it is perpendicular to the applied force, and the angle between the applied force and the pedal sprocket arms is 90⁰.
Also, when the pedal sprocket arms are in the vertical position, it is parallel to the applied force, and the angle between the applied force and the pedal sprocket arms is 0⁰.
Explanation:
τ = r×F×sinθ
where;
τ is the torque produced
r is the radius of the pedal sprocket arms
F is the applied force
θ is the angle between the applied force and the pedal sprocket arms
Maximum torque depends on the value of θ,
when the pedal sprocket arms are in the horizontal position, it is perpendicular to the applied force, and the angle between the applied force and the pedal sprocket arms is 90⁰.
τ = r×F×sin90⁰ = τ = r×F(1) = Fr (maximum value of torque)
Also, when the pedal sprocket arms are in the vertical position, it is parallel to the applied force, and the angle between the applied force and the pedal sprocket arms is 0⁰.
τ = r×F×sin0⁰ = τ = r×F(0) = 0 (torque is zero).

E = (6.62 x 10^-34 x 3 x 10^8)/0.0275 x 10^-9
E = 7.22182 x 10^-15 J
To convert to eV divide by 1.6 x 10^-19
E = 7.22182 x 10^-15/1.6 x 10^-19 eV
E =45.36 x 10^3 eV
Th energy, E, of a single x-ray photon in eV is = 45.36keV.
Number of photons, n = total energy/ energy of photon
n = 3.85 x 10^-6/7.22182 x 10^-15

Answer:
The angular displacement would be 6 Pi radians or 1080 degrees.
Explanation:
Every individual rotation is 2 Pi (this applies to anything regardless of radius).
Since there are three rotations you are going to multiply 2 Pi by 3.
This will give you 6 Pi which you can convert to equal 1080 degrees (1 Pi = 180 degrees).
Answer:
M = 6.32 x 10⁻⁶ H
Explanation:
given,
Length of solenoid = 10 cm = 0.1 m
diameter = 0.40 cm
radius = 0.2 cm = 0.002
number of turns, N₁ = 800
N₂ = 50
mutual inductance will be equal to
M = 6.32 x 10⁻⁶ H
hence, mutual inductance of the combination of two coil is equal to M = 6.32 x 10⁻⁶ H
