Answer: c) the sun is the most massive object; gravitational attraction is related to mass.
Explanation:
Gravitational pull exists between any two objects having mass.
where symbols have their usual meaning.
All the planets including Earth revolve around the Sun because its the most massive object in the neighborhood and thus has high gravitational pull. This gravitational pull of Sun keeps the Earth in its orbit around it.
Hence, the correct answer is earth orbit the sun rather than any other body in the solar system because c) the sun is the most massive object; gravitational attraction is related to mass.
Answer:
Explanation:
If we ASSUME that angular acceleration is constant and the desired output is angular distance.
The average angular velocity is
ω = (3 + 25) / 2 = 14 rad/s
θ = ωt = 14(10) = 140 radians
Answer: B>A=D>C
Explanation:
Kinetic Energy is the product of mass and square of the velocity
For Jogger A
For Jogger B
For Jogger C
For Jogger D
Kinetic Energy of Joggers in increasing order
B>A=D>C
Answer:
m = 4.4 × 10³ kg
Explanation:
Given that:
The total yearly energy is 4.0 × 10²⁰ J
The amount of mass that provides this energy can be determined by using the formula:
E = mc²
where;
c = speed of light in free space = (3 × 10⁸)
4.0 × 10²⁰ = m × (3 × 10⁸)²
m = 4.4 × 10³ kg
