Explanation: Well, think about it if you see it on the logical end, there are 8 men that mean 16 legs. Then there are 4 legs of the couch as well that made it total of 20. If broken legs are of the men, then still the total will be 20 because the legs are still intact but 6 men left that means 12 legs are gone, if 3 legs break and 6 men leave. the number of legs remaining are 20–6*2–3=5.... so it's 5 I hope this helps! xoxo
The study of the moon as well as the stars is astronomy
We use a spectrometer to help us determine what stars and planets are made of by passing a light through various chemical elements, different spectral patterns are created. By matching those patterns up to patterns generated in a laboratory environment we can tell what the composition of a distant star or planet is.
Answer:
as an object gains speed it gains kinetic energy
Explanation:
i am mixed with the very first one i dont really know if its right so if its wrong my bad
The correct answer is
increasing velocity.In fact, the fact that the object has an acceleration different from zero means that the velocity of the object is changing. If the acceleration is in the direction of the motion, then it is a positive acceleration, therefore the velocity is increasing. The law of velocity for an object in accelerated motion is in fact

where

is the initial velocity, a the acceleration and t the time. When a is positive (same direction of the motion), then the term (at) is increasing as t becomes larger, therefore the velocity v(t) is increasing as well.
