B. Exactly the same as the electric force of the electron on the proton.
<u>Explanation:</u>
Even if the mass of proton is increased or decreased, the force between electron and proton will remain the same because force is dependent on the charge of the object and distance between them. The force between the charges is independent of their masses. So, even if the mass of a proton is 1833 times larger than the mass of an electron, the force between them will be same.
According to Coulomb's law:

where,
F is the force
q₁ and q₂ are the charges
r is the distance between the charges
Since the two trains are passing in opposite
directions, so this means that their relative velocities will be the sum of the
two trains that is:
<span>
relative velocity = (13 + 28) = 41m/s</span>
<span>
a. The passengers aboard on train B will see that train A is
moving at 41m/sec due east</span>
<span>b. The passengers aboard on train A will see that
train B is moving at 41m/sec due west</span>
Balance would be the answer to this questions
They cause magnetic storms. A magnetic storm is a fleeting
disturbance of the Earth's magnetosphere. A magnetic storm is caused by a solar
wind shock wave associated with solar coronal mass ejections, coronal holes, or
solar flares. It typically strikes the Earth's magnetic field 24 to
36 hours after the event.
First we can calculate the average speed v in km/h by the equation v=s/t where s is the distance traveled and t is the time:
First we turn time into seconds and divide by 3600 to get time t in hours is:
t=13*3600 s + 4*60 s + 58 s= 47098 s and that is:
t=47098s/3600s=13.08278 hours
So v=1633.8/13.08278=124.88 km/h
To get speed in m/s we simply turn kilometers into meters and hours into seconds:
s=1633.8 km *1000 = 1633800 m
t=13*3600s + 4*60 s + 58 s=46800 s + 240 s + 58 s=47098 s
v=s/t=1633800/47098=34.67 m/s
So average speed in km/h is v=124.88 km/h and in m/s is v= 34.67 m/s.
