Describe what it meant by "a constant change of direction". Identify whether the examples provided show a constant change of direction when moving.(S8P3a) a. A merry-go-round spinning in circles.
b. A wind vane swinging around.
c. A person running at 5 meters/second along a curving path.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

i believe the answer is electric potential.
