Can someone help with my physics homework? will get 15 points A go cart engine applies a force of 888N and moves the cart forward 22m.
a) How much work is done?

b) What is doing the work?

c) If the driver wants to go further will the amount of work increase or decrease? Do you need a bigger engine to go
further?

d) We put on a bigger engine (1111N) but the cart still moves forward 22m. How much work is done now?

e) Why would you put on a bigger engine if you are still moving 22m?

f) Work requires a change in energy, which engine uses more gas to go 22m?

g) Even an empty semi truck uses much more gas than a car. Why?Find the soultions

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ΒΊc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in Γ—10^{-3} βˆ’3 m)
