Answer:
The magnitude of the centripetal force that acts on him
Explanation:
Given that,
Mass = 80.0 kg
Distance = 6.10 m
Speed = 6.80 m/s
We need to calculate the magnitude of the centripetal force that acts on him
Using formula of the centripetal force

Where, F = force
m = mass
v = speed
r = distance
Put the value into the formula


Hence, The magnitude of the centripetal force that acts on him
Answer:
Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain
hope this helps
have a good day :)
Explanation:
How fast they are falling
Scientists believe that most animals survived the 2004 Asian Tsunami because they had perceived its coming and they prepared for it. It is believed that animals can hear and perceive infrasonic sound and Rayleigh waves which are usually the warming signs of a coming tsunami. Scientists believed that the animals felt the shaking of the ground as a result of the Rayleigh waves and hear the infrasonic sounds which can not be heard by humans. This makes the animals to flee to higher grounds [above sea level] for safety.
Volum at the beginning:

Volum at the end:


α for helium =

As the result you get:

Final volume of the balloon is 22,9264 liters.
(Only if it doesn't explode during being heated ;) just a joke)
