The person must stand at a radius of 0.99 m
Explanation:
In order for the person to stand on the merry go round, the force of friction acting on the person must provide the centripetal force necessary to keep the person in uniform circular motion.
Therefore, we can write:

where:
- the term on the left is the force of friction, and the term on the right is the centripetal force
is the coefficient of friction
m is the mass of the person
is the acceleration of gravity
is the angular velocity
r is the radius of the circular path
Solving the equation for r, we find the radius at which the person must be standing:

Soil contains vermiculite, a natural mineral.Even though Vermiculite holds water, it can be dangerous for the human body. It's filled with naturally occurring asbestos, and when asbestos is breathed in, it can risk our respiratory system. In addition, soil has a potentially serious disease causes from bacteria called Legionnaires' Disease. It's very dangerous, especially for the people with a weak immune system.
Hope this helps.

The answer is "Conduct an experiment" :)
Answer:
Explanation:
Let assume the first connect have resistor R1 and R2
Then, this are connected in parallel
But, parallel connection of resistor have the same voltage.
So the power dissipated in each resistor is given as
P1=V²/R1
P2= V²/R2
If another resistor is added in parallel nothing change by the way each resistor dissipate power
Then, power dissipated in R3 is
P=V²/R3
Why we use parallel circuit at home
Parallel circuits are used in homes because the loads can be operated independently of each other.
Each load gets the full voltage of the circuit.
