Distance is the total length of an object's path. Displacement is the overall change in position, ie. how far an object is from its initial position.
The court is 30 m long, so a path going back and forth once is 60 m long. Going along this path 6 times totals 360 m.
The end point is the same as the starting point, so the displacement is 0 m.
The first step that Enrique must take in order to calculate the tangential speed of the satellite is to convert the period from days to seconds.
We know that the SI unit of speed is meter per second and now, we with to obtain the tangential speed of the satellite.
Since the period is given in days, the first step is to convert the period from days to seconds.

<u>Answer:</u>
If a car weighs 6310 N on earth, its mass = 643.22 kg.
<u>Explanation:</u>
Weight of a body is given by the product of it's mass and acceleration due to gravity on that planet.
So weight of body in earth = mass of body* acceleration due to gravity on earth.
Acceleration due to gravity in earth =
Here it is given weight of car = 6310 N
So we have, 6310 = mass of car* 9.81
Mass of car = 6310/9.81 = 643.22 kg.
So If a car weighs 6310 N on earth, its mass = 643.22 kg.
Answer:
The frequency of green light is 7.14*10¹⁶ Hz
Explanation:
Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. it is expressed in units of length (m).
Frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).
Propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave's disturbance propagates throughout its displacement. Relate wavelength (λ) and frequency (f) inversely proportional using the following equation: v = f * λ.
So, light has an exact speed of 299,792,458 kilometers per second, which usually approaches 3 * 10⁸ m/s.
Then, you know:
- v= 3 * 10⁸ m/s
- f=?
- λ= 4.2*10⁻⁹ m
Replacing:
3*10⁸ m/s=f*4.2*10⁻⁹ m
Solving:
f= 7.14*10¹⁶ Hz
<u><em>The frequency of green light is 7.14*10¹⁶ Hz</em></u>
