Answer: 4 AU
Kepler's third law states that square of orbital period of a planet is proportional to the cube of the average distance from the Sun.
where, T is the orbital period, r is the average distance from Sun, G is the gravitational constant and M is the mass of the Sun.
If T is in Earth years, M is in Solar mass (1 Solar mass = mass of sun), r is in AU (astronomical unit) then:
Answer: Option (d) is the correct answer.
Explanation:
Physical change is defined as a change in which no new product is formed, that is, there is no change in chemical composition of a substance.
For example, when ice melt then solid state of water changes into liquid state.
That is, arrangement of atoms changes and bond between the atoms do no break during a physical change.
Thus, we can conclude that the property bonds between atoms do not break; it is only the arrangement that changes explains why matter is conserved in a physical change.

Answer:
The magnitude of the impulse experienced by the particle is 100 kg.m/s.
Explanation:
Given;
mass of the particle, m = 5 kg
initial velocity of the particle, v₁ = 10 m/s
assuming the particle rebounds with same velocity backwards, v₂ = - 10 m/s
The impulse experienced by the particle is the change in linear momentum;
J = ΔP = mv₁ - mv₂
J = m(v₁ - v₂)
J = 5 (10 - (-10))
J = 5 (10 + 10)
J = 5(20)
J = 100 kg.m/s
Therefore, the magnitude of the impulse experienced by the particle is 100 kg.m/s.
