Answer:
10989.55932 rad/s
Explanation:
m = Mass of object
M = Mass of neutron star =
R = Radius of neutron star = 13000 m
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
= Angular speed
Here, the gravitational force will balance the centripetal force
The greatest possible angular speed an object can have is 10989.55932 rad/s
According to galilo in the absence of air resistance fraction then the body mass 60kg and 40kg will reach the earth surface at the same time....
True, nuclear reactions, whether they are fission or fusion depend on generating energy by converting a certain amount of mass by breaking the atom or combining two atoms together.
Answer:
v = - 14.08 m / s
Explanation:
The definition of center of mass is
= 1 /M ∑sun
where M is the total mass of the system and and are the position and mass of each component.
The velocity of the center of mass can be found by deriving this expression with respect to time
= 1 / M ∑ m_{i} vi
let's find the total mass
M = m₁ + m₂ + m₃ + m₄
M = 1.45 + 2.81 +3.89 + 5.03
m = 13.18 kg
let us substitute in the velocity of the center of mass = 0
0 = 13.18 (m₁ v₁ + m₂ v₂ + m₃v₃ + m₄v₄)
v₄ = - (m₁ v₁ + m₂ v₂ + m₃v₃) / m₄
let's substitute the given values
v₄ = -[1.45 (6.09 +0.299 t) +2.81 (7.83 + 0.357t) +3.89 (8.09 + 0.405 t)] / 5.03
They ask us for the calculations for a time t = 2.83 s
v₄ = - [8.8305 + 1.227 + 22.00 + 2.839 + 31.47 +4.4585] / 5.03
v = - 14.08 m / s
The correct choice would be
B) The Sun’s mass is much greater than Earth’s
The sun as we know has greatest mass in our solar system and lighter objects tends to orbit around the heavier objects. the mass of earth is very much smaller as compared to that of the sun. hence the earth orbits around the sun due to the force of gravitational attraction between the two objects.
