Explanation:
It is given that,
Mas of the car,
Initial speed of the car,
Mass of the truck,
Initial speed of the car,
Final speed of the car,
(a) It is a case of elastic collision. Let is the final velocity of the truck right after the collision. Using the conservation of linear momentum to find it :
(b) Initial kinetic energy is given by :
Final kinetic energy is given by :
The change in mechanical energy of the car truck system in the collision:
The loss in kinetic energy is 10029.39 Joules.
(c) The change in mechanical energy gets changed energy gets changed in the form of heat and light.
Hence, this is the required solution.
If you read the question carefully, you can find the answer right there in it.
In fact, you don't even have to read the whole question ... you only need to read one word.
In fact, you don't even have to read the whole word ... you only need to read part of the word.
The word to read is "wavelength".
The important part of the word is "length".
<em>Now</em> it's time to look at the picture:
#1 is a height.
#2 is a place on the wave
#4 is a place on the wave
<em>#3 </em>is the only thing in the picture that's a "length" of anything.
Answer:
9.9 m
Explanation:
From the question given above, the following data were obtained:
Force (F) = 40 N
Workdone (Wd) = 395 J
Height (h) =?
The height can be obtained as follow:
Potential energy = mgh = Fh
395 = 40 × h
Divide both side by 40
h = 395 / 40
h = 9.9 m
Thus, the height is 9.9 m.
15 minutes because 60 minutes divided by 4 mph equals 15 minutes per mile
A, B & C
This phenomenon is defined as <em>relativity of simultaneity</em> by Albert Einstein.
Depending on the motion of an observer, the observer may perceive a distinct event occurring at a specific time differently from another observer with different motion.
Explanation:
This is stipulated in Albert Einstein's theory of special relativity that stipulates that the two distinct events that occur at the same time but at different places in space may appear differently to different non-accelerating observers at different vantages points (or reference frames). This is due to the interrelated nature of space and time hence it called space-time.
