Gravity is important not only for life on Earth, but for the makeup of the entire galaxy. Gravity holds our solar system and galaxy together and is responsible for orbital motions within them. The diagram shows the order of planets' orbits based on distance from the Sun, while the chart provides numerical distances from the Sun Compare the diagram and chart and think about each planet's orbital pattern and distance from the Sun Based on the information given, what
conclusion can be drawn about diagram?

a) the farther out from the sun the greater a planet’s gravitational pull

b)the planets in the solar system are about the same distance from one another

c) the planets order from the sun is based on their size from smallest to largest

d) the diagram does not accurately represent the distances of planets from the sun

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
