You and your neighbour are shovelling snow. If your neighbour pushes a shovel four times as far as you do but exerts only a half the force, which one of you does more work and by how much?

The neighbour

Double your work

Explanation:

Work is a product of force and distance, expressed as W=Fd where W is work in Nm, F is applied force and d is the distance in m

Since your neighbour pushes 4 times then you just push 1m when he pushes 4m, that is an example. Also, since the neighbour only exerts half the force ie 0.5N then you exert full force of 1N

Work from your neighbour will be 4d*0.5F=2dF

Work from you will be dF

Clearly, 2dF=2(dF) hence the neigjbour exerts double work

which three statements are true about all alloys?

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
