You need to clean and sand wood of any ruff edges
Answer:
As the pressure inside the pressure cooker increases as it is heated, the temperature also increases.
Explanation:
A pressure cooker contains water and steam in equilibrium at a pressure greater than atmospheric pressure.
According to the ideal gas law, as the pressure increases, the temperature also increases.
As the pressure inside the pressure cooker increases as it is heated, the temperature also increases.
Kinetic energy=0.5*mass*(velocity^2)
15,000 J=0.5*50*v^2
15,000J=25v^2
600 J=v^2
Velocity= 24.49 ms^-1
Answer:
decreases by a factor of 4
Explanation:
Lets take mass of the objects are m₁ and m₂ and the distance between them at initial condition is R.
We know that attraction force between two object given as

G=Constant
If distance become 2 R
R' = 2R





Therefore we can say that gravitational force will become one forth of the initial force.
