Answer:
The astronaut will be propelled towards the shuttle at the rate of 0.4 m/s.
Explanation:
Given;
mass of the astronaut, m₁ = 95 kg
mass of the hammer thrown, m₂ = 2 kg
velocity of the hammer, v₂ = 19 m/s
let the recoil velocity of the shuttle = v₁
Apply the principle of conservation of linear momentum;
m₁v₁ = m₂v₂
v₁ = m₂v₂/m₁
v₁ = (2 x 19) / 95
v₁ = 0.4 m/s
Therefore, the astronaut will be propelled towards the shuttle at the rate of 0.4 m/s.
Answer: touch the pan to the burner
Explanation:
There are three modes of heat transfer:
conduction, convection and radiation.
For conduction, the heat transfers from a hot object to a cold object when the two are in contact.
For convection there is bulk motion of fluid occurs which transfers the heat.
For heat transfer by radiation, medium is not required.
Thus, to demonstrate conduction between pan and burner, the pan must touch the burner.
It’s going to be both answer A and B but if you can only answer one then it’s going to be B
By what i know i think that the answer would be A a homogeneous mixture.
