Answer:
Their kinetic energies would be the same
Explanation:
This is because, since the force, F acting on them moves the same distance, d, the work done by the force is W = Fd.
Now, from work-kinetic energy principles,
W = ΔK where ΔK = change in kinetic energy of the carts.
Since the work-done is the same for both carts, their change in kinetic energies would also be the same.
Since they start from rest, ΔK = K' - K = K' - 0 = K'
So, the kinetic energies of the carts would be the same
Si here is my best guess, hope it helps and it’s right
Answer:
2.39 °C
Explanation:
Specific heat of water = 4187 j / kg °C (You eaither have to be given this, or know this or look it up)
100 g of water = .1 kg of water
1000 j / (.1 kg * °C) = 4187 j / (kg °C)
solve for C = 2.39°C
