Answer:
The smallest radius will be four (4) times the initial radius
Explanation:
The car maintains a constant angular speed. According to Newton's Second Law F = m a
1. 
2. 
Replacing 2 in 1
3. 
Where:
Fr= Frictional force
Rp= Initial Radius
An= Centripetal Acceleration
M= Mass
V= Velocity
Also we have that:
4. 
μ= Coefficient of friction between the car and the surface
M= Mass
W= Weight
G= Gravity
r is cleared from equation 3
5. 
Replacing 4 in 5
6. 
Simplifying
7. 
Now we have a new velocity equal to twice the initial velocity, We replace it by 2v in equation 7
8. 
Computing
9. 
Replacing 5 in 9
I think it is C but I don’t know for sure
Answer:
True
Explanation:
Stellar-sized black holes form when a star explodes in a supernova is a true statement. Supernova occurs when a huge size star collapses into itself. This explosion is massive such that parts of the stars are thrown apart. And this phenomenon gives rise to super massive black holes. Supernova occurs when the core becomes very heavy and star is not able to hold its won weight.
Most likely the baseball because it weighs less therefore with the same force it will go further due to the fact it weighs less it would be easier to apply force and the less it weighs there is also less force acting upon it.
