Answer:
option D
Explanation:
the correct answer is option D
acceleration of a body under free fall due to the effect of gravity is the called acceleration due to gravity.
Acceleration due to gravity is a constant value.
According to the International System of Measurements the acceleration due to gravity is 9.81 m/s² when an object falls vertically.
acceleration due to gravity is denoted by 'g'.

<span>The star is a ball of hot gases
containing different kinds of elements at different cores. It has a very high
temperature that radiates all throughout the galaxy. The star has four
main parts; the core, photosphere, chromospheres and corona. The outer core of
a star located at the chromospheres contains mostly of hydrogen. Inside the hydrogen
is helium then carbon, oxygen, neon, magnesium silicon and the inert gas. When a
star releases energy it is due to the thermonuclear fusion of hydrogen into
helium. So the answer is fusion.</span>
The first question is open series circuit.
The second question is closed series circuit.
Answer:
The answer is below
Explanation:
Newton's law of gravity states that the force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. The law is expressed by the formula:
The masses and distances for this question is in common units, Therefore the result would be in ratios
a) 4 MEarth / 2 MSolar / 3 AU
The force (F) = (4 * 3) / 3² = 4/3
b) 1 MEarth / 1 MSolar / 1 AU
The force (F) = (1 * 1) / 1² = 1
c) 1 MEarth / 2 MSolar / 2 AU
The force (F) = (1 * 2) / 2² = 1/2
