First we calculate the Electric Force
F = qE = 1.6E-19 * 4 E+4 = 6.4 E -15 N
This Force is equal to mass*acceleration
F = m*a
Mass of the electron = 9.1 E-31 Kg
Mass of the proton = 1.67 E -27 Kg
Acceleration of electron = 6.4 E -15 / 9.1 E -31 = 7.033 E 15 [m/s**2]
Acceleration of proton = 6.4 E -15 / 1.67 E -27 = 3.832 E 12 [m/s**2]
The first one is decreases because there are less molecules in the air.
The second on would be the last option, August 29, because a new moon occurs every 29 days.
The answer for the last one would be A, I presume, because when air masses arrive at a destination, it becomes dry.
Answer:
and the forces acting on the particle as a function of time.
Explanation:
The principle of linear impulse and momentum is obtained by integrating the equation of motion with respect to time. hope this helps you :)
Energy is lost due to friction so it cannot be D, it also cannot be C since you can only have friction during movement, and potential energy is when you have the potential of having an amount of said energy, and friction slows things down, therefore it must be B.
Answer:
velocity changes over time.
