Answer: 1) Boils</h3>
The less air pushing down on the water effectively allows the water to boil easier. Think of the water molecules as a bunch of marbles bouncing around in a box with a lid. The less air pressure means the lid is easier to open from the force exerted by the bouncing marbles, allowing those particles to escape and turn into gas.
So in short, if you are in the mountains, then it'll take less time to cook food because water comes to a boil faster.
If earth was not tilted on a axis, we wouldn't have any seasons. we wouldn't have seasons because the axis tilts us towards or away from the sun, and if you're tilted torwards the sun the sun you would have summer. if you're tilted away from the sun, you have winter. if there was no axis, the temperature would be the same all around the earth, so therefore we would not have seasons.
hopefully this helps
Machines makes work easier by increasing the amount of force that is applied, and changing the direction in which the force is applied !! Hope it helped (p.s. I had this same question)
The weight of an object is (mass) x (gravity).
The weight of Mr. McDonald's object is (112) x (9.8) = <u>1,097.6 newtons</u>.
(about 247 pounds)
That's the force pulling the object down, because it is near the Earth, and
the Earth and the object are attracting each other with forces of gravity.
In order to move the object away from the center of the Earth ("lift" it), a force greater than 1,097.6 newtons must be applied to it <em>in the other direction</em> ... <u>upwards</u>.
<em><u>Any</u></em> force greater than its weight will lift it. The more the upward force exceeds the minimum of 1,097.6 newtons, the faster Mr. McDonald's object will <u>accelerate</u> upwards.
