With which comet is the annual perseid meteor shower associated?

Explanation:

Perseid meteor shower is annually observed in August. This phenomenon occurs because the pieces of the Swift-Tuttle comet (also called 109P / Swift-Tuttle and discovered by Lewis Swift in 1862 and by Horace Parnell Tuttle in 1862, independently) collide with the Earth atmosphere at high speeds.

This is also due to the debris cloud formed by the pieces of cometary residue moving along parallel orbits, so when entering the atmosphere they leave burning traces that seem to come from a common radiant point in the sky, located in this case at the Perseus constellation.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
