Answer:
the doppler effect shows stars with red shifted light
Explanation:
light from a receding star is shifted toward red or redshifted
redshift is an example of the doppler effect
the wavelength of the light is stretched so the light is seen as shifted towards the red part of the spectrum

Explanation:
A truck travelling at 22.5 m/s decelerates at 2.27 m/s2. (a) How much time does it take for the truck to stop? (b) How far does it travel while stopping? (c) How far does it travel during the third second after the brakes are applied?
We can use the "suvat" method
s is displacement
u is initial velocity
v is final velocity
a is acceleration
t is time
We substitute in what we know...
s = ?
u = 22.5 (the speed/velocity the trucks is initially)
v = 0 (the truck comes to a stop)
a = -2.27 (negative because it is decelerating
t = ?
[tex]\text{suvat formulae}:\\v = u + at\\s = ut + \frac{1}{2}at^2\\v^2 = u^2 + 2as\\s = \frac{v+u}{2}t\\s = vt - \frac{1}{2}at^2[/tex]
We have [tex]u[/tex], [tex]v[/tex], [tex]a[/tex] and we want to find the time for how long it takes the truck to stop.
We can use [tex]v = u + at[/tex]
[tex]v = u + at\\0 = 22.5 - 2.27 \times t\\\frac{-22.5}{-2.27} = t\\t = 9.91...\ \text{s}[/tex]
To find the distance (displacement), we can use [tex]s = ut + \frac{1}{2}at^2[/tex]
[tex]s = ut + \frac{1}{2}at^2\\s = 22.5 + \frac{1}{2} \times -2.27 \times 9.91^2\\s = -88.9661935\ \ \text{(we make it positive since you can't have negative distance)}\\s = 88.97...\ \text{m}[/tex]
To find the distance travelled 3 seconds after breaks are applied;
We just use the same formula, but with [tex]t = 3[/tex]
[tex]s = ut + \frac{1}{2}at^2\\s = 22.5 \times 3 + \frac{1}{2} \times -2.27 \times 3^2\\s = 12.285\ \text{m}[/tex]
The distance between a Point on one wave and the same point on the next cycle of the wave
Answer:
wavelength
Explanation:
the definition of wavelength is the distance between two consecutive waves. with that being said, the point from the crest of one wave to the crest of another would be wave length
A car moving south speeds up from 10 m/s to 40 m/s in 15 seconds. What is the car’s acceleration?
Explanation:
Initial velocity ( u ) = 10 m/s
Final velocity ( v ) = 40 m/s
Time taken ( t ) = 15 second
Now
[tex]acceleration = \frac{v - u}{t} \\ = \frac{40 - 10}{15} \\ = 2m /{s}^{2} [/tex]
if lens behave like prism and disperse light then why person using glass on eye can't see colour being dispersed?
Answer:
A prism can disperse light into different colors when the light enters the prism at a "fixed" angle - light coming in, perhaps, thru a narrow slit
If light can enter at all angles, then dispersion occurs at all angles and no dispersion can be seen

The speed of the light wave will remain the same.
Answer:
The Speed Of The Lightwave Will Be Modified As It Enters Another Medium (State Of Matter)
Explanation:
As The Lightwave Enters The Medium The Light Will Bend Toward The Normal E.g. Incident Ray Which Indicates It Will Modify It's Speed But When it Leaves The Medium It Will Increase Until As It Leaves The Sold

A big pendulum goes back and forth
once every 18.9 s. What is the
length of the pendulum?
(Unit = m)
T = 2π√(L/g)
For earth , g ~ 10
18.9 = 2×3.14 √(L/g)
9 = L/g
L = 90 metres
Answer:
88m
Explanation:
T=2π*[tex]\sqrt{L/g}[/tex]-->Τ/2π=[tex]\sqrt{L/g}[/tex]-->18.9/2π=[tex]\sqrt{L/g}[/tex]-->3=[tex]\sqrt{L/g}[/tex]-->3^2=L/g-->9=L/9.8
so L=9*9.8-->L≈88m
Each degree on the Kelvin scale equals how many degrees on the Celius scale
Answer:
0° C = 273.15 K
0 K = - 273.15° C
Explanation:
Hello there!
The Kelvin temperature scale refers to the absolute temperature scale. The division in the Kelvin scale is equal to a degree on the Celsius scale only it's difference is zero
The Celsius scale of zero (0°C) is the freezing point.
0 K is Absolute Zero.
•°• 0 K = - 273.15° C
0° C = 273.15 K
Furthermore, this is what I would like you to know about this scales;
The Kelvin scale is used for very low or very high temperatures where water is not involved.
Note:
The boiling point of water is 100°C.
I hope this helps you to understand more on this scales. Have a nice studies.

Will the positioning of your Slinky along the east-west, north-south, or some other orientation affect your readings? Why?
Positioning your Slinky along any direction different from its initial position will affect your reading, because there will be change in the magnetic field.
Effect of magnet on Slinky
If the Slinky is made of an iron alloy, it can be magnetized by itself. Moving the Slinky around can cause a change in the magnetic field, even if no current is flowing.
When there is a change in the magnetic field, the reading changes.
At any point, you change the orientation of the Slinky, you will need to zero the reading or adjust the Slinky back to its initial position, even if the sensor does not move.
Thus, Positioning your Slinky along any direction that is different to its initial position will affect your reading because there will be change in the magnetic field.

If I want to calculate the normal force of an object on two legs but the weight of the object is not uniform throughout, how do I go about calculating such a problem?
Use the right equation. To calculate the normal force of an object at an angle, you need to use the formula: N = m * g * cos (x) For this equation, N refers to the normal force, m refers to the object's mass, g refers to the acceleration of gravity, and x refers to the angle of incline.

Why wave energy is different from other types of energy? Describe in your own words
Answer:
it is the most concentrated form of renewable energy on earth, with power density much higher than that of wind and solar energy.
Explanation:
The advantages of wave energy include being free, sustainable, renewable, and producing zero waste. Therefore, it can contribute to reducing our carbon footprint. It is also unique since it is the most concentrated form of renewable energy on earth, with power density much higher than that of wind and solar energy.
A force of 600N is applied to an object that accelerates at a rate of 15m/s/s. What is the mass of the object?
Answer:
The answer will be it has a mass of 40 kg.
Explanation:
Because Force = mass x acceleration or F = m a, we can say Force divided by mass or F/a = m or mass so 600 divided by 15 equals 40 kg.
