Displacement = (distance between start and end points) in the direction of (direction from start to end point). Distance = (11.3-3.38)= 7.92 m. Direction = the negative 'x' direction.

Answer:
B. If the container is cooled, the gas particles will lose kinetic energy and temperature will decrease.
C. If the gas particles move more quickly, they will collide more frequently with the walls of the container and pressure will increase.
E. If the gas particles move more quickly, they will collide with the walls of the container more often and with more force, and pressure will increase.

The distance starting from the point to the lighthouse would be regarded as the hypotenuse.
And also will be the radius of the circle the beam of light is generating at that point.
So get the radius first
r = sqrt (1^2 + 5^2)
r = 5.099 km
find the circumference:
C = 2*pi * 5.099 km
C = 2 * 16.01898094
C = 32.04 km
Then find the speed in km/sec
One revolution: 60/2 = 30 sec per revolution
Speed = 32.04 km/30 sec
S = 1.068 km/sec is the speed of light
The centripetal acceleration of the space shuttle is 
(0.9g)
Explanation:
The period of revolution of the space shuttle is
From the period, we can calculate the angular speed of the space shuttle, which is given by
Now we can calculate the centripetal acceleration of the space shuttle, given by
where
is the angular speed
is the distance of the shuttle from the Earth's centre (it is the sum of the Earth's radius, 6400 km, and of the altitude of the space shuttle, 300 km)
Substituting and solving, we find
And since 
, this can be rewritten as
