Answer:
i may be wrong but i believe its 02--->S02
Answer:
The force used
Explanation:
This has to be because of the force used. Both Susie and her younger brother might have hit the ball with the same velocity, but they surely couldn't have hit it with the same force. The force with which Susie hurts it is heavier than that with which her younger brother hits it, and as such, Susie gets to fall down more pins than her brother will be able to. The ball has to have a lot of force in it for it to be able to knock off all the pins there. So basically, the more the force, the higher it's chances of hitting all the pins
Remember that since energy is conserved, the kinetic energy it takes to jump to a height of 1.2 m is just the same as the potential energy difference between ground level and the 1.2 m height.
Potential energy = (mass)(gravity)(height) = (7.2 kg)(9.81 m/s^2)(1.2 m) = 84.76 J
Therefore, the kinetic energy required for the dog to jump to a 1.2-m height is 84.76 Joules.
Answer:
63.05 cm²
Explanation:
We use Pascals law to find the answer.
The law says that in an incomprehensible , non-viscous fluid the pressure applied will transmit through out the fluid without a change.
So, Pressure on larger piston = pressure on smaller piston.
A ≅ 63.05 cm²
