Answer:
increases by a factor of 
Explanation:
First we need to find the initial velocity for it to stop at the distance 2d using the following equation of motion:
where v = 0 m/s is the final velocity of the package when it stops, 
is the initial velocity of the package when it, a is the deceleration, and 
is the distance traveled.
So the equation above can be simplified and plug in Δs = d, 
for the 1st case
(1)
For the 2nd scenario where the ramp is changed and distance becomes 2d, 
(2)
let equation (2) divided by (1) we have:
So the initial speed increases by . If the deceleration a stays the same and time is the ratio of speed over acceleration a
The time would increase by a factor of
Answer:
In the electromagnetic spectrum, "Blue" is the "highest" frequency color of visible light.
Or In the electromagnetic spectrum, "Red" is the "Lowest" frequency color of visible light.
Hope this helps!
The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.
not giving you the answer but hopefully this gives a hint
Answer: UV wave
Explanation:
Ultraviolet light (UV light), whose wavelength is approximately between 100 nm and 380 nm; is a type of electromagnetic radiation that is not visible to the human eye.
This type of radiation is an important factor in the photosynthesis process, in which the Ultraviolet light is transformed into stable chemical energy, converting inorganic matter into organic matter. This process is carried out by living beings that are mostly made up of <u>chlorophyll</u> (a green pigment), such as plants and algae.
In addition, UV light is important in making vitamin D in humans, becausa this vitamin is synthesized by the skin from cholesterol, through a chemical reaction that needs short-wave ultraviolet rays (also called UVB).
Answer:
(a) 24.87 GHz (b) 3.55 GHz
Explanation:
We have given the speed of the spaceship =0.75 c, here c is the speed of the light
(a) In the first case the ship is moving towards the alpha century
So the frequency is given by 
(b) In this case the ship is moving away from the alpha century
So frequency is given by
