I believe it's A: Convection, which is caused by air circulating because of uneven heating.
Answer: A forest fire could affect the geosphere by ash and the heat from the fire, but the fire would affect the biosphere by less oxygen in the air and would make it hard for human to breath affecting climate change. Also many homes to wildlife that live in the forest would lose their homes. This would result in lose of money from no hunting and that affect the economy.
A release of a large amount of energy
Answer:
Yes to answer is 3/5 of what
Answer:
5.5 rad/s
Explanation:
The friction between the coin and the turntable provides the centripetal force that keeps the coin in circular motion. Therefore, we can write:
where
is the coefficient of friction
m is the mass of the coin
is the acceleration of gravity
is the angular speed
r is the distance of the coin from the centre of rotation
In this problem,
r = 11.0 cm = 0.11 m
The coin starts to slip when the centripetal force becomes larger than the maximum frictional force:
Solving for , we find the angular speed at which this happens:
