Dr. Martin is an ophiologist, or a scientist who studies snakes. During one experiment, Dr. Martin fed a snake a whole mouse and compared the mass of the snake before it consumed the mouse to the snake's mass immediately after it was fed. According to the law of conservation of mass, how should the masses compare? A. The mass of the snake after feeding should be equal to the original mass of the snake plus the mass of the mouse. B. The mass of the snake after feeding should be equal to the mass of the mouse. C. The mass of the snake after feeding should be the same as the original mass of the snake. D. The mass of the snake after feeding should be equal to the original mass of the snake minus the mass of the mouse.

how to make a simple air condition

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
