Answer:
the Earth orbits the Sun because of the pull of the Sun's gravity. This happens because the Earth has a acceleration in the direction perpendicular to the force of the Sun's pull and if the Sun weren't there, the Earth would travel in a straight line.
Explanation:
The correct answer is B. Most prevalent in living things. It is also helpful to know that SPONCH stands for S - Sulfur, P - Phosphorous, O - Oxygen, N - Nitrogen, C - Carbon, and H - Hydrogen; these are key elements that compose living things.
Answer:
Angle between the forces 
degrees
Explanation:
The resultant force value 
times of Force F
Where R is the resultant force
Cos X is the angle between the two forces.
On further simplifying the equation we get
degrees
Angle between the forces degrees
B. It provides information about why certain measurements are made in an experiment
From experience, to be able to have background research helps in the design of an experiment because it would tell you what is being measured in a experiment. Without the background information, my whole class got lost on what to do until my teacher told us what we had to measure and how we could measure the experiment.
