Light travels best through empty space because there is nothing to block/disrupt its path.
Correct answer choice is :
D) The marble’s horizontal velocity changes, but its vertical velocity does not.
Explanation:
Projectile motion is a kind of change undergone by an object or particle that is submitted near the Earth's cover and runs along a rounded path under the act of gravity only. This curved way was given by Galileo to be a parabola. The regular segment of the speed of the object continues constantly during the motion. The vertical segment of the changes linearly, because the acceleration due to pressure is uniform. The accelerations in the x and y tracks can be combined to determine for the segments of velocity at any time t.
the answer would be B. the back emf increases, and the current drawn from the socket increases
more current is needed to make the motor move, like when you try to self crank a motor and the back wires are touching its harder to crank. and the emf increases since more current is being drawn in, strengthening the emf or increasing the emf
Answer:
The magnetic field is strongest at the center and weakest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.
Explanation:
True the elements are ordered in the atomic number
