Answer:
D
Explanation:
A material that has a high resistivity and prevents charges from moving freely... it is part of insulators...
It travels fastest through solids.
Answer:
Average velocity of water flow through the pipe = 3.98 m/s
Explanation:
Diameter of pipe = 20 mm
Discharge = 75 L/min
We know that
Discharge = Area x Velocity

Discharge = 75 L/min

Substituting

Average velocity of water flow through the pipe = 3.98 m/s
Gravity acts to influence the vertical motion of the projectile, thus causing a vertical acceleration. The horizontal motion of the projectile is the result of the tendency of any object in motion to remain in motion at constant velocity.
