First you must calculate the acceleration of the puck using F=ma. The force F is negative .14 N, the frictional force, and the mass is .12 kg. Solving for a=F/m, we get a=-1.17 m/s^2. Now we use a kinematic equation. vf^2=vi^2 + 2ax. We need to solve for x. We know the final speed vf is 0 because we are finding the stopping distance. Initial velocity vi is given as 18.3 m/s. We just found acceleration a is -1.17 m/s^2. Now we need to solve for displacement x, which is the answer to the question. Plugging in the appropriate values to the kinematic equation gives us 0=18.3^2 - 2(1.17)x. 2(1.17)x=18.3^2. x=143 m
B. The writer didn't mention anything significant .
Explanation:
example: humans (biosphere) can build a dam out of rock materials (geosphere) or water in a lake ( hydrosphere ) seeps into the cliff walls behind the dam becoming ground water ( geosphere) or evaporate into the air ( atmosphere)
<h2>
Answer: joules</h2>
Explanation:
From the first law of thermodynamics,
Δ=Δ+
Where is the heat given to the gas,
is the internal energy of the gas,
is the workdone by the gas.
When pressure is constant,
When pressure is constant,Δ
Where is pressure and is the volume of the gas.
Given
Δ
So,
Given that Δ
So,Δ
