Answer:
d = 3.5*10^4 m
Explanation:
In order to calculate the displacement of the airplane you need only the information about the initial position and final position of the airplane. THe initial position is at the origin (0,0,0) and the final position is given by the following vector:
The displacement of the airplane is obtained by using the general form of the Pythagoras theorem:
(1)
where x any are the coordinates of the final position of the airplane and xo and yo the coordinates of the initial position. You replace the values of all variables in the equation (1):
hence, the displacement of the airplane is 3.45*10^4 m
Answer: a= 52.02 m/s²
Fc= 78.03 N
Explanation: Solution attached:
You multiply the high length and width and if your using centimeters then divide by 500 and then there's your answer.hoped this helped.
Yes
Explanation:
From the graph, we can deduce that the wavelength changes with the speed of the wave.
This is a simple linear graph. A linear graph has a steady gradient and it shows two variables that increases proportionately.
Using the graph, we can establish that as the wavelength of the wave increases the time taken for one wave to pass through increases.
The speed of a wave is given as:
V = fλ
f is the frequency of the wave i.e the number of waves that passes through a point per unit of time
λ is the wavelength of the wave
The vertical axis on the graph shows the time for 1 wave trip, this is the wave period, T
f = 
Therefore;
speed of the wave = 
This can be evaluated by solving slope of the graph and finding the inverse.
We can see that as the speed of the wave changes, the wavelength will change.

Answer:
from vacuum to air
Explanation:
Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.
- When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
- Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.
The correct option must be from a less dense medium to a denser medium.
density of glass = 2500 kg/m³
density of air = 1.275 kg/m³
density of ice = 919 kg/m³
density of water = 1000 kg/m³
density of plastic = 940 kg/m³
density of vacuum = 6.5 x 10⁻²⁷ kg/m³
The two possible options are;
from ice to water
from vacuum to air
The difference in densities of ice and water is not larger compared to vacuum and air.
If you are required to choose two options, the two options are correct
But if it is only one option, then from vacuum to air is the correct answer.
Therefore, the correct option is from vacuum to air
