Friction, engine thrust, normal reaction and weight, these are the forces acting on motor when it moves in a straight line
Answer:
The two major sources of energy for the rock cycle are also shown; the sun provides energy for surface processes such as weathering, erosion, and transport, and the Earth's internal heat provides energy for processes like melting, and metamorphism

Explanation:
Alexis and Kym arrange to meet at the running track to train for an athletics carnival. They cycle to the track, leaving their homes at the same time. It takes Alexis 8 minutes to travel 2800 m from her home to the track. Kym takes 18 minutes,
after travelling a distance of 6.12 km.
Alexis thought she was faster, but Kym was not convinced. Who do you think was faster? Give reasons for your answer.
Answer:
V = 31.62 m V
Explanation:
Given,
Voltage across thick membrane = ?
Thickness of the membrane, d = 5.5 n m
Electric field = 5.75 M V/m
we know
V = E d
V = 5.75 x 10⁶ x 5.5 x 10⁻⁹
V = 31.62 x 10⁻³ V
V = 31.62 m V
Hence, The Voltage across the membrane is equal to 31.62 m V.
That n2 = 2*n1. That is, the index of refraction is twice as big in medium 2 since v=c/n
