Answer:
Teh velocity of ball with respect to the ground is 29.2 m/s.
Explanation:
Velocity of car, vc = 25 due m/s east
velocity of ball with respect to car, v(b,c) = 15 m/s due Z axis
Write the velocities in the vector form
The velocity of ball with respect to ground is
Answer:
200J
Explanation:
200J is 100%, 10% of 200J would be 20J
Theories have both an explanatory an a predictive function. True
Heat energy can move through a substance by conduction. Metals are good conductors of heat, but non-metals and gases are usually poor conductors of heat. Poor conductors of heat are called insulators. Heat energy is conducted from the hot end of an object to the cold end.
Technician A is Correct.
You can see this when he says that conductors have more free electrons than insulators. This statement is True.
While Technician B says that, insulators have the lower resistance than conductors. This statement is False.
