Eight students (Anna, Brian, Carol, ...) are to be seated around a circular table with eight seats, and two seatings are considered the same arrangement if each student has the same student to their right in both seatings.(a) How many arrangements of the eight students are there?(b) How many arrangements of the eight students are there with Anna sitting next to Brian?(c) How many arrangements of the eight students are there with Brian sitting next to both Anna and Carol?(d) How many arrangements of the eight students are there with Brian sitting next to either Anna or Carol?
please explain how u got the numerical answer for each part, like what you multiplied to get it

Alice is driving a race car around an essentially circular
track. Brian, who is sitting at a fixed position at the
edge of the track, measures the time that Alice takes to complete a
lap by starting his watch when Alice passes by his position (call
this event E) and stopping it when Alice passes his positin again
(call this event F). This situation is also observed by
Cara and Dave, who are passengers in a train that passes very close
to...

A spaceship of mass ? is on a circular orbit around a planet of
mass ?, and is moving with constant speed ?0.
(a) What is the radius of the orbit of the spaceship?
A sudden explosion tears the spaceship into two pieces of equal
mass. Piece 1 leaves the explosion with speed 4?0/5 with its
velocity is in the same direction of the velocity of the spaceship
before the explosion. As ? ≪ ?, the gravitational attraction
between the...

A satellite is placed in an elongated elliptical (not circular)
orbit around the Earth. At the point in its orbit where it is
closest to the Earth, it is a distance of 1.00 × 10^6
m from the surface (not the center) of the Earth,
and is moving at a velocity of 5.14 km/s. At the
point in its orbit when it is furthest from the Earth it is a
distance of 2.00×10^6 m from the surface of the
Earth....

Eight people, named Anna, Bob, Chandra, Darlene, Ed, Frank,
Gina, and Hank, will be interviewed for a job. The interviewer will
choose two at random to interview on the first day. What is the
probability that Darlene is interviewed first and Ed is interviewed
second? Express your answer as a fraction or a decimal, rounded to
four decimal places.

A satellite in a circular orbit around the earth with a radius
1.011 times the mean radius of the earth is hit by an incoming
meteorite. A large fragment (m = 81.0 kg) is ejected in the
backwards direction so that it is stationary with respect to the
earth and falls directly to the ground. Its speed just before it
hits the ground is 361.0 m/s. Find the total work done by gravity
on the satellite fragment. RE 6.37·103 km;...
