Once the cannon fires its projectile, does the horizontal velocity of the projectile increase, decrease or stay constant over time? How do you know?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

Apersons beliefs and general outlook, which act like filters on the information they receive are called ?
