Reil [10]3 years ago

Answer:

Rain jackets are coated in durable water-repellant (DWR) finish, a hydrophobic glaze that allows the coats to be breathable, yet waterproof. It lets water vapor—like sweat—out, but keeps rain from getting in. ... Without a DWR, the raincoat is just a coat. So, you'll need to recoat it.

Explanation:

This is according to the web

Mean is the same thing as average, so to find this you would add all of the numbers together and divide them by the amount of numbers you added. For example, (6+9+11)/3

Median is the middle number of the list of numbers, but you have to put them in numerical order first. If there is not an exact middle, you would add the middle two together and divide by two.

Mode is the number that occurs most often within the list of numbers.

A man pushes a lawn mower on a level lawn with a force of 250N. If 40% of this force is directed downward, how much work is done
Dvinal [7]
When considering work, we always take the force directed along the axis of motion (in this case, the horizontal axis). If 40% of the force is directed downward, then 60% of the force is being directed horizontally, so the horizontal force is 250*0.6 = 150N. Work = Force * distance = 150N * 6.2m = 930J
