Answer:
By a positive charge
Explanation:
The electric field is a vector consisting of a magnitude and a direction.
- The magnitude of the field depends on the configuration of the field: for example, for the electric field produced by a single point charge, it is

where k is the Coulomb's constant, q is the magnitude of the charge, r is the distance from the charge.
- The direction of the field corresponds to the force that a positive charge would feel in that field. For example, the electric field produced by a single-point positive charge points away from the charge itself: this is because a positive test charge placed in this field would feel a repulsive force, so it would move away from the source of the field. Vice-versa, the electric field produced by a single-point negative charge points towards the charge itself: this is because a positive test charge placed in this field would feel an attractive force, so it would move towards the source of the field.
Answer:
(B) Parachutes
Explanation:
Air resistance works to slow down trains and airplanes, so it isn't desirable. Air resistance also causes pendulums to slow and stop.
Parachutes need air resistance to slow a person's fall. So air resistance is desirable here.
Answer:
The rock cycle is the process by which rocks of one kind change into rocks of another kind. ... Metamorphic rock is igneous or sedimentary rock that has been heated and squeezed. It can erode into sediment or melt into magma.
Explanation:
Resistance = (voltage) / (current)
= (12 v) / (2 A) = 6 ohms .
