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?

Answer:

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

Is bleach heterogeneous

No, bleach is not heterogeneous. Bleach is actually homogeneous. 
Heterogeneous is if it the same throughout. 
Homogeneous is if it is different (has chunks and clumps of different materials)

an apple in a tree has a gravitational potential energy of 175J and a mass of 0.36g . how high from the ground is the apple
Neko [114]
The equation for potential energy is denoted as; 

Pe = mgh,

where m = the mass, g = acceleration due to gravity, and h = vertical height of the apple. We are given the units for everything but height, which is also what we are solving for. We can then algebraically rearrange our initial equation to solve for h;

h = (Pe)/(mg)

Plug in your given units, and solve!





Post-check:

h = Pe/mg

h = 175J/(0.36g)(-9.81m/s^2)

h = appr. 49.5 meters

Note: Potential energy is a vector quantity; the displacement of the apple will be a negative number, but the distance itself, a scalar quantity, will be the absolute value of that.

How much force is needed to accelerate a 68 kilogram skier at a rate of 1.2m/sec
xxMikexx [17]

Let's use Newton's 2nd law of motion:

                                     Force = (mass) x (acceleration)

                                     Force = (68 kg) x (1.2 m/s²) =  81.6 newtons .
