Well plants breathe carbon and let out oxygen so it cleans the air, not sure about the energy use...

I would go with choice C) rub some treatment on it because A) is just plain useless since putting your fingers in your mouth is getting u germs so no, not B) because yes even though cold is the opposite of hot, u don't know what type of burn she may have so u can actually hurt yourself more with the water or even be infected, and definitely not D) because that wont really solve it, its best to see a doctor or professional who can help you.

The water skier has a mass of 73 kg. Find the magnitude of the

Papessa [141]

To solve this problem we will apply the linear motion kinematic equations, specifically the concept of acceleration as a function of speed and time, as well as Newton's second law.

PART A) Acceleration can be described as changing the speed in a period of time therefore,

$a = \frac{V}{t}\\a = \frac{11}{8}\\a = 1.375m/s^2$

Force is the proportional change between mass and acceleration therefore

$F = (73)(1.375)$

$F= 100.375N$

PART B) We will apply the same concept given but now we will change the time to 21s therefore:

$a = \frac{V}{t}\\a = \frac{11}{21}\\a = 0.5238$

Now the force

$F = (73)(0.5238)$

$F = 38.23N$
