The physical changes are you are breaking down the food u eat and the chemical changes are when the enzymes in your stomach break down the food that you have already eaten

Physical change - Macro-molecules splits into smaller particles, and so their size would reduce

Chemical change - They splits into their monomers, like Proteins convert into amino acids, fats into glycerol and fatty acids etc

Hope this helps!

How long would it take to travel one light year?

Llana [10]

It depends on what speed you are going at. Assuming you are in our fastest spacecraft as of now which has a speed of 17,500 mph
1 light second = 186,282 mph
There are <span>31,536,000 in one year so 17,500x=31,534,000 and your answer would be in years. It would take you roughly 1802 years.</span>
(Sorry about mph I'm American.)

A 3-ton Toyota land cruiser travelled at a speed of 45m/s, collides with a 2- ton comfort taxi which was parked in front of the

Olin [163]

Answer:

v = 27 m/s

Explanation:

To find the speed of cars after the collision you take into account the momentum conservation law. Total momentum of both cars before the collision must be equal to the total momentum of both cars after the collision.

After the collision both cars traveled together, then you have:

$m_1v_1+m_2v_2=(m_1+m_2)v$ (1)
