Then the speed of the rider is, v = 2m/s
The linear velocity of an object in a straight line is its speed.
The following is the relationship between linear and angular velocity:
v = rω
The circumference of the bicycle wheel is,
2
r = 2
r = 0.318m
The angular velocity of the wheel is,
ω = 1rev/sec = 2
rad/s
Then the speed of the rider is,
v = rω
v = 0.318×2π
v = 2m/s

Answer:the car is speeding up
Explanation:
It would be A. 10 Hertz
A average human can hear between only 20Hz - 20,000Hz
Answer:
Explanation:
Every chemical reaction can be represented by simple chemical equations that shows how compounds are combining to give some products.
Such reactions are usually made up of:
Reactants on the left hand side
Products on the right hand side
Reactants → Products
In this given problem;
Reactants are : Magnesium fluoride = MgF₂
Iodine in form of Iodide = I₂
Product : Magnesium iodide = MgI₂
MgF₂ + I₂ → MgI₂ + F₂
