Answer:
The rotation of Earth on its axis causes electric currents to form a magnetic field which extends around the plane
Explanation:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents.
Yes it may or may not be depending on the angle of the ramp. But if nothing is specified then it must be related to acceleration as friction is neglected.
Answer:
Photoelectric effect
Explanation:
In the photoelectric effect, when an x-ray strikes on a metal surface, the energy is completely absorbed by the metal. If the energy would be equal to or more than work function of metal, electron ejects out. The kinetic energy of the electron which is ejected depends on the energy of the incident radiation and work function of the metal.
Answer:
25 m
Explanation:
Given:
v₀ = 10 m/s
v = 0 m/s
a = -2 m/s²
Find: Δx
v² = v₀² + 2aΔx
(0 m/s)² = (10 m/s)² + 2 (-2 m/s²) Δx
Δx = 25 m
