We know that a charge moving in a magnetic field is subject to the force:
F = q · v · B
But we also know that:
F = m · a
Therefore, it must be:
m · a = <span>q · v · B
And solving for a:
</span>a = <span>q · v · B / m
Recall that for a proton:
q = 1.6</span>×10⁻¹⁹ C
m = 1.673×10⁻²⁷ kg
Now, you can find:
a = 1.6×10⁻¹⁹ · 7.0 · 1.7 / <span>1.673×10⁻²⁷
= 1.14</span>×10⁹ m/s²
Hence, the acceleration of the proton is 1.14<span>×10⁹ m/s²</span>.
Answer:
0.859375c
31.03 seconds
Explanation:
v' = Velocity of my ship = 0.4 c
u = Velocity of rocket = 0.7 c
c = Speed of light = 
s = Distance between my ship and enemy ship = 
Relativistic addition of speed is given by

The speed of the missile is 0.859375c
Time is given by

It will take 31.03 seconds to reach me.
Answer:
A. Shear stresses are maximum at the neutral axis and normal stresses are maximum furthest from the neutral axis.
Explanation:
Normal stress :
Normal stress is defined as the stress or the restoring force that occurs on the plane when an external axial load is applied on it. For a beam the normal stress is maximum at the point furthest from the neutral axis and is zero at the neutral axis of the beam.
Shear stress :
Shear stress is a stress which occurs when the force acts on the surface of the member in a parallel direction. It changes the shape of the member. For a beam, the shear stress is maximum at the neutral axis.
Okay! Thank you for this knowledge
Answer:
µ = 
Explanation:
µ = 1/ sinC
µ -----> refractive index of medium
C ----> critical angle
