Answer:

Strong Positive Linear Line Correlation

Explanation:

According to the diagram, there is a strong positive linear line correlation between velocity and distance of galaxies. Hubble showed that galaxies are receding away from people with a velocity that is proportional to their distance from people more distant galaxies recede faster than nearby galaxies.

About the diagram: Velocity is the distance relation among extra-galactic nebulae. Radial velocities is corrected for solar motion, are plotted against distances estimated from involved stars and mean luminosities of nebulae in a cluster. The black discs and full line represent the solution for solar motion by using the nebulae individually; the circles and broken line represent the solution combining the nebulae into groups; the cross represents the mean velocity corresponding to the mean distance of 22 nebulae whose distances could not be estimated individually.

A 730-N man stands in the middle of a frozen pond of radius 5.0 m. He is unable to get to the other side because of a lack of fr
STatiana [176]

Answer:62.11 s

Explanation:

Given

weight of man =730 N

mass of man m_1=\frac{730}{9.8}=74.48 kg

radius of pound r=5 m

mass of book m_2=1.2 kg

velocity of book v_2=5 m/s

let v_1 be the velocity of man

conserving momentum

0=m_1v_1+m_2v_2

0=74.48\times v_1+1.2\times 5

v_1=\frac{6}{74.48}=0.0805 m/s

time taken by man to reach south end

t=\frac{5}{0.0805}=62.11 s

List two fossil fuels. describe in general how fossil fuels were formed.
vazorg [7]

Fossil Fuels:

Coal and Oil

How they are formed:

Coal is formed from big plants, from a long time ago. When the big plants died, they formed layers at the bottom of swamps and the dirt began to pile up and it formed Coal.

Oil is a fossil fuel that has been formed from a large amount tiny plants and animals such as algae and zooplankton.
