Suppose the Earth had a second moon twice as far from the Earth as our present moon. Using Kepler's 3rd Law calculate the time (period) this new moon will take to orbit the Earth
The time taken for the new moon to orbit the earth is √8 times the time taken by the present moon.
According to Kepler's third law,
[tex]T_{m} ^{2}[/tex] = ( 4 π / G [tex]m_{E}[/tex] ) r³
[tex]T_{m}[/tex] = Time taken by the moon
G = Gravitational constant
[tex]m_{E}[/tex] = Mass of Earth
r = Radius of moon
r' = 2 r
r' = Radius of new moon
[tex]T'_{m} ^{2}[/tex] = ( 4 π / G [tex]m_{E}[/tex] ) ( 2 r )³
[tex]T'_{m} ^{2}[/tex] = 8 ( 4 π / G [tex]m_{E}[/tex] ) r³
[tex]T'_{m}[/tex] = √8 [tex]T_{m}[/tex]
Kepler's third law states that square of time period of a planet's orbit is equal to the cube of semi-major axis of the orbit.

A person walks the path shown below. The total trip consists of four straight-line paths.
Path 1 is 40.0 m due east.
Path 2 is 230.0 m due south.
Path 3 is 110.0 m 30.0° south of west.
Path 4 is 180.0 m 60.0° north of west.
At the end of the walk, what is the person's resultant displacement?
The resultant displacement is (- 145 i - 130 j )m and the angle made by the resultant is 46° west of the South, this can be found using the polygon law of vector addition.
What are vectors?Physical quantity that has both magnitude as well as direction a vector is represented by a line ending with an arrow head where the length of the line represents the magnitude of the vector and the direction of the arrowhead represents the direction of the vector.
What is the polygon law of vector addition?If two or more vectors are joined head to tail then the polygon law of vector addition states that the resultant of such a vector will be given by the vector addition of all the vectors present in the polygon.
Given:
Magnitude of vector 1 pointing south = 40m
Magnitude of vector 2 pointing south = 230 m
Magnitude of vector 3 pointing south of west = 110m
Magnitude of vector 4 pointing north of west = 180 m
Using the polygon law of vector addition we get,
The resultant displacement = vector 1 + vector 2 + vector 3 + vector 4
The resultant displacement = 40 i - 230 j - 110 × cos 30 i - 110 × sin 30 j- 180 × sin 60 j + 180 × cos 60
The resultant displacement = 40 i - 230 j - 95 i - 55 j + 155 j - 90 i
The resultant displacement = ( - 145 i - 130 j )m
To find the angle of the resultant vector we will use tangent trigonometric ratio.
Tan x = (-145)/(-130)
Tan x = (145)/(130)
x = 46° to west of South
Where,
x is the angle made by resultant vector with the vertical axis.
Therefore, the resultant displacement is ( - 145 i - 130 j )m and the angle made by the resultant is 46° to the west of the South.

A car drives 26.8 m/s south. It
accelerates at 3.75 m/s² at a
155.0° angle. How long does it
take until the car is driving directly
west?
Answer: the time for the car to drive directly south is determined as 7.15 s.
Explanation:
The time for the car to drive directly south is determined by applying the concept of slope.
slope = Δy/Δx
a = Δv/Δt
Δt = Δv/a
Δt = (26.8)/(3.75)
Δt = 7.15 s
Thus, the time for the car to drive directly south is determined as 7.15 s.

[tex]\lambda[/tex]=1.77-Angstrom = 1.77×10^-10
we know the relationship betwee frequency and lambda
c=λν
ν=c/[tex]\lambda[/tex]
ν is frequency , [tex]\lambda[/tex] is wavelength, and c is speed of light
c= 3×10^8m/s
now put the value in equation:

When a wave travels from one place to another, its frequency describes how frequently a medium particle vibrates. The frequency of a wave may be calculated mathematically by counting how many full oscillations are produced during its propagation in one unit of time. The number of waves that pass a given location in a unit of time may thus be used to characterize it.The unit of frequency is cycles per second or vibrations per second.

by the rocket? (b) How long after lift-off does the rocket
reach its maximum height? (c) How long is the rocket in
the air?
The maximum height reached by the model rocket is 300.5 metre. (b) Time to reach maximum height is 8.5 seconds and (c) the time for which the model rocket was in air is 17.3 seconds.
What are Newton's law of motion?Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it.
Given:
Initial velocity of the model rocket = 50m/s
Constant acceleration of rocket = 2 u
Height to which acceleration was in account= 150m
First we need to find the final velocity at 150 metres.
We can do so simply by using Newton's third law of motion,
Velocity at 150 metre = under root (2500 + 600)
Velocity at 150 meter = 55.7
Maximum height height reached by the model rocket can be find using the equation for max height.
.i.e. maximum height = u × u/2g + initial distance traveled
maximum height = 55.7×55.7/19.6 + 150
maximum height = 156.5 + 150
Maximum height= 300.5 m
Time taken to reach maximum height = time taken before acceleration stops + time after which acceleration stops
Time taken to reach maximum height = 5.7/2 + 55.7/9.8
Time taken to reach maximum height = 2.85 + 5.7
Time taken to reach maximum height = 8.5 seconds
The rocket will be air for the time = time to reach maximum height + time to fall to the ground
The rocket will be air for the time = 8.5+ 7.8
The rocket will be air for the time = 17.3 seconds.
Therefore, the maximum height reached by the model rocket is 300.5 meter, time to reach maximum height is 8.5 seconds and the time for which the model rocket was in air is 17.3 seconds.

For a truck moving at constant speed...
1. the distances traveled during each time period are the same. 2. the direction traveled during each time period must be the same.
3. the truck must accelerate.
4. all of these.
Answer:
1.) the distances travelled during each time period are the same
Explanation:
1.) is correct. If the speed is constant, the truck is moving the same distance per every time period. For example, if the truck is moving at 50 miles/hour, the truck will always travel 50 miles per every 1 hour.
2.) is incorrect. Unlike the velocity, speed is non-directional. This means a truck can maintain a constant speed regardless of its orientation.
3.) is incorrect. Acceleration is the rate at which the velocity/speed changes. If the speed is constant, the acceleration is 0.
4.) is incorrect.

Having come late to practice, a baseball player is forced to run from one side of the 100-meter field and back three times, which takes him 345 seconds. What is his average velocity throughout the task?
The average velocity for completing three rounds of the basketball court would be zero as initial and final position would be zero and the average speed would be 3.28 m/s.
What is average velocity ?Average velocity is defined as the total displacement divided by the total time take to compete the total displacement.
What is average speed ?Average speed is defined as the total distance divided by the total time take to compete the total distance.
Given:
Side of the baseball court = 100 meter
Total time taken to complete three rounds of the basketball court = 375 seconds
Total distance traveled by the player can be measured using the given side of the basketball court.
First we will find the parameter of the court,
Parameter of the court = 4 times the side of basketball court
Parameter of the basketball court = 4 × 100
Parameter of the basketball court = 400 metre
The player goes for 3 rounds of the basketball court which makes the total distance three times the parameter of the basketball court.
Total distance traveled by the basketball player = 3 × 400
Total distance traveled by the basketball player = 1200 metre
Average velocity is displacement divided by time taken.
Total displacement = 0 metre
As the player reaches the same position from where he started so the total displacement is zero.
Therefore, average velocity = 0/365
average velocity = 0 m/s
Average speed = 1200/365

Mass flow rate of water in gpm = 34.5625 g
1. Mass flow of brine
1gm = 8.35 lb / min
Therefore, 25 gm = 25 * 8.35 = 208.75 lb / min

b. The angle between the positive x axis and the total force that the cockpit seat exerts on the 76- kg pilot is 67⁰.
Force exerted on the pilot by the cockpit
The force exerted on the pilot by the cockpit is calculated as follows;
F = ma
where;
m is mass of the pilot
a is acceleration of the jet
F = 3.8 m/s² x 76 kg
F = 288.8 N
The total force exerted on the pilot is equal to the normal reaction of the pilot.
F = Fn
F = mg cosθ
cos θ = F/mg
cos θ = (288.8) / (76 x 9.8)
cos θ = 0.3878
θ = arc cos (0.3878)
θ = 67⁰
Thus, the magnitude of the total force that the cockpit seat exerts on the 76- kg pilot is 288.8 N.
