If there's no air resistance, then there are no horizontal forces on the ball.
With no horizontal force, there's no horizontal acceleration, so the horizontal speed never changes. From the time it's tossed until it hits the ground, its horizontal speed is the same 5 m/s. (B)
Electric
field strength = Electric force/charge
E = F/q
E = (1.8×10^-1) / (6.4×10^-7)
E = 2.81×10^5 NC^-1

Full answer in the attached picture
Answer:
B- Opposes the motion
Explanation:
When two object touches each other. friction acts in a opposite direction to the motion of the object
Atomic number is equal to the number of protons and electrons
Atomic mass - protons = neutrons
protons + neutrons = atomic mass
