The coefficient of static friction is 0.222
Explanation:
In order for the car to remain in circular motion, the frictional force must be able to provide the necessary centripetal force. Therefore, the car will start skidding when the two forces are equal:

where the term on the left is the frictional force, while the term on the right is the centripetal force, and where
is the coefficient of static friction
m is the mass of the car
g is the acceleration of gravity
v is the speed of the car
r is the radius of the track
In this problem, we have:
r = 564 m
v = 35 m/s

And re-arranging the equation for
, we can find the coefficient of static friction:

c. The Moon is positioned directly between the earth and the sun is the statement that does not result in an eclipse.
Explanation:
- The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun.
- it is just the right distance away from Earth, the Moon can fully blocks the Sun's light from Earth's perspective
Answer:
Certain Things Make Light Bend?
Explanation:
Transparent Objects/ things can make light bend when entering through it.
Answer:
A simple pulley is a wheel with a rope that allows you to pull one end and have it lift whatever is on the other end. A modern, common example of this is a crane, often used in construction.
Explanation:
1) A) Object 1 has the greater momentum
The magnitude of the momentum of an object is given by:

where
m is the mass of the object
v is its speed
Object 1 has a mass of
and a speed of
, so its momentum is

Object 2 has a mass of
and a speed of
, so its momentum is

So we see that
, so object 1 has the greater momentum.
2) The objects have the same kinetic energy.
The kinetic energy of an object is given by

where
m is the mass of the object
v is its speed
Object 1 has a mass of
and a speed of
, so its kinetic energy is

Object 2 has a mass of
and a speed of
, so its kinetic energy is

So we see that
, so the objects have same kinetic energy
