<h3>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.

Describe the effects of forces on an object in motion

Shkiper50 [21]

Please clarify what it says in the picture. All I can say right now is to remember Newton's first law of motion; an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force.

A home gets its water from the public supply. Which of the following would be the best way for the homeowner to obtain a water-q

diamong [38]

The correct option is C.
Since the home gets its water from public supply, the best place to get the water quality report is from the local water treatment facility who processed the water. Water quality report is a document which summarizes information about the water sources that are used, detected contaminants, compliance observed, etc.

A 75-kilogram hockey player is skating across the ice at a speed of 6.0 meters per second. What is the magnitude of the average

saveliy_v [14]

Answer:

(3) 690 N

Explanation:

Force: This is the product of mass and acceleration of a body. The S.I unit of force is Newton(N).

The formula for force is given as,

F = ma..................... Equation 1

Where F = force, m = mass, a = acceleration.

Also,

a = (v-u)/t................... Equation 2

Where v = Final velocity, u = initial velocity, t = time.

Given: u = 6.0 m/s, v = 0 m/s (bring to stop), t = 0.65 s.

Substitute into equation 2

a = (0-6)/0.65

a = -6/0.65

a = -9.23 m/s²

Also given: m = 75 kg

Substitute again into equation 1

F = 75(-9.23)

F = -692.25 N

The negative sign tells that the force oppose the motion of the player

F ≈ 690 N

Hence the right option is (3) 690 N

Bob weighs 80 pounds. He ran up the steps which rose 14 feet. Fred weighs 110 pounds. He ran up the same steps as Bob. If both b

pav-90 [236]

Bob gained (80lbs x 14ft) = 1120 ft-lbs of energy.

Fred gained (110lbs x 14ft) = 1540 ft-lbs of energy

Since they both took the same amount of time, Fred's power (rate
of doing work) was greater than Bob's power (rate of doing work).
