Answer:
wavelength, frequency, energy and speed
Explanation:
kinematic equation

Electrons have a negative charge, so if you give away electrons, you give away negative charge, thus ending with a positive charge.
Answer:
graph A
Explanation:
the slope of the distance-time graph is speed, speed is a scalar (with magnitudes but no direction)
but the slope for the velocity time graph is acceleration, acceleration is vector quantity ( has magnitude and direction)
