ill give brainliest What will the acceleration of a falling 8 kg object be if it has 7 Newtons of air resistance?
Answer:
Given:
M= 8kg
F= 7N
Unknown:
Acceleration of a falling object
Formula:
a = F/m
Solution and Final Answer:
a = 7 kg.m/s² ÷ 8 kg
a = 0.88 m/s²
because the divisor and dividend there are the same units so cancel it(kg) then the rest is m/s² so it will be the unit of 0.88 will become 0.88 m/s²

Explanation:
Jamie did an experiment to find out whether cola, diet cola, or water would freeze quickest. She poured three equal amounts of each liquid into paper cups and put all the paper cups in the same freezer. Then she timed how long it took the liquid in each cup to freeze. What should Jamie do to analyze her data?
A. Find the average time it took each liquid to freeze.
B. Look at her data and estimate the answer.
C. Repeat the experiment two more times.
D. Conduct another experiment with other liquids.
Answer:
It would be C.
Explanation:
To receive the most accurate data, she should repeat the experiment multiple times.
A falling skydiver is accelerating in the downward direction at 3.29 m/s^2. The mass of the skydiver (including parachute gear) is 67.2 kg. Determine the air resistance force on the skydiver (and accompanying parachute).
Answer:
The force due to air resistance on the skydiver is 438.1 N.
Explanation:
You need to balance forces. If we use the following notation:
Net force on skydiver = F
Force on skydiver due to gravity = F(grav)
Force on skydiver due to friction or air resistance = F(air)
Then:
F = F(grav) - F(air)
because the force of air resistance acts against the force from gravity. You can rearrange this to get:
F(air) = F(grav) - F
Then you can use the equation F = ma to get:
F(air) = ma(grav) - ma
where:
m = mass of skydiver (given in question) = 67.2kg
a(grav) = acceleration of an object due to gravity = g = 9.81 m/s/s on Earth
a = actual acceleration (given to you in question) = 3.29 m/s/s
Simplify the equation to get:
F(air) = m * [g - a]
F(air) = 67.2 * [9.81 - 3.29]
F(air) = 67.2 * [6.52]
F(air) = 438.1 N
When the parachute is opened, the surface area increases, which increases air resistance.
The force due to air resistance on the skydiver is 438.1 N.
What happens to air resistance when a parachute opens?When the parachute is opened, the surface area increases, which increases air resistance. Because air resistance has surpassed weight, the resulting force acts upwards. The parachutist slows down; a lower velocity means less air resistance. At a lower terminal velocity, air resistance and weight become equal.However, the faster the parachute falls, the more drag it creates. The drag force resists gravity's downward movement, pushing the parachute back up. The drag of the parachute increases as it falls until it just balances out the pull of gravity.Net force on skydiver = F
Force on skydiver due to gravity = F(grav)
Force on skydiver due to air resistance = F(air)
Then:
F = F(grav) - F(air)
because the force of air resistance acts against the force from gravity. You can rearrange this to get:
F(air) = F(grav) - F
Then you can use the equation F = ma to get:
F(air) = ma(grav) - ma
where:
m = mass of skydiver (given in question) = 67.2kg
a(grav) = acceleration of an object due to gravity = g = 9.8m/s^2 .
a = actual acceleration (given to you in question) = 3.29 m/s/s
Simplify the equation to get:
F(air) = m * [g - a]
F(air) = 67.2 * [9.81 - 3.29]
F(air) = 67.2 * [6.52]
F(air) = 438.1 N.

In physical weathering, how are ice and plant roots similar?
Both break open rocks by expanding in a crack.
Both cause abrasion and slowly break down rocks.
Both require many cycles of freezing and melting.
Both result from dramatic changes in temperature.
Answer:
A break open rocks from in cracks
Explanation:
Ice freezes in the crack and expands. Plants start growing in the crack and grow out of it. Both of these cause the rock to slowly break in half from the crack.

Why does air rush out of an inflated balloon? ONLY REAL ANSWERS = BRAINLIEST ABSURD, WRONG ANSWER = REPORT
Answer:
When a balloon is inflated we increase the pressure inside the balloon so that the pressure inside the balloon is greater than the pressure outside the balloon. The escaping air in one direction provides the force in the opposite direction for the balloon to go in the opposite direction.
