Answer:
a) equal 1, b) less than 1
Explanation:
a) the electric force is given by
Fe = q E
The charge of the electron and proton has the same value, that of the proton is positive and that of the electron is negative
Proton
Fp = qE
Electron
Fe = - q E
Fp / Fe = -1
If we do not take into account the sign the relationship is equal to one (1)
b) to calculate the force we use Newton's second law
F = ma
qE = m a
a = q E / m
The mass of the proton much greater than the mass of the electron
ap = q E / 
ae = - q E / 
ap / ae = /
= /1600 =1/1600
It is much smaller than 1
A common misconception is that scientific theories are rudimentary ideas that will eventually graduate into scientific laws when enough data and evidence have been accumulated. A theory does not change into a scientific law with the accumulation of new or better evidence.
Ball is thrown at an angle of 20 degree with velocity 18 m/s
so first we will find the two components of the velocity
similarly for other component
now the ball will cover horizontal distance of 30 m till it reach to other player
so here we can use the formula of time
so it will take 1.77 s to reach the other player
The correct answer that would best complete the given statement above would be "<span>the G main sequence star is less massive than the O main sequence star. " </span>A G main sequence star spends far more time on the main sequence than an O main sequence star because the G main sequence star is less massive than the O main sequence star. Hope this answer helps.
