Lipids are found in the sugars and starches, and are the main sources of energy in the body.
Answer:
The man's total displacement is equal to 0.
Explanation:
Given that,
A man ran a 5 mile race. The race looped around a city park and back to the starting line.
We need to find the total displacement of the man.
We know that,
Displacement = shortest path covered
Also,
Displacement = final position - initial position
As it reaches back to its starting line, it means, the displacement is equal to 0.
Hence, the man's total displacement is equal to 0.
Answer:
Car radiators: Water is used as coolant car radiators. Due to its high specific heat capacity, it can absorb a large amount of heat energy from the engine of the car, but its temperature does not rise too high.
Explanation:
i hope this answer your question if it s wrong please let know
Answer:
According to wavelengths in descending order: C, B, D, E and A
According to frequencies in descending order: A, E, D, B and C
According to speeds in vacuum: A =B =C =D =E
Explanation:
in the EM spectrum, radio waves have the longest wavelength while gamma rays have the shortest wavelength.
All EM waves travel with the same speed of 
in a vacuum.
First we can say that since there is no external force on this system so momentum is always conserved.
now by the condition of elastic collision
![v_{2f} - v_{1f} = 0.8 - 0[\tex]now add two equations[tex]3*v_{2f} = 1.6](https://tex.z-dn.net/?f=v_%7B2f%7D%20-%20v_%7B1f%7D%20%3D%200.8%20-%200%5B%5Ctex%5D%3C%2Fp%3E%3Cp%3Enow%20add%20two%20equations%3C%2Fp%3E%3Cp%3E%5Btex%5D3%2Av_%7B2f%7D%20%3D%201.6)
also from above equation we have
So ball of mass 0.6 kg will rebound back with speed 0.267 m/s and ball of mass 1.2 kg will go forwards with speed 0.533 m/s.
