The ratio of the distance a bullet travels to the amount of time it takes to travel is known as the speed or velocity of the bullet, depending on whether we need to know the direction or not. Speed is a scalar quantity. It describes to "how fast an object is moving", in our case how fast the bullet is moving.Velocity is a vector quantity. velocity describes "the rate at which an object changes its position".
v = 400m/58s = 6.9m/s
v = 400m/60s = 6.7m/s
6.9m/s - 6.7m/s = .2m/s difference
60sec - 58 sec = 2 sec
v =Δx/t
Δx = vt
Δx = (.2m/s)(2sec)
Δx = .4m
therefore, the answer is .4m
Explanation:
gas vibrate and move freely at high speeds, liquid vibrate, move about and slide past each other. solid vibrate (jiggle) but generally do not move from place to place
Answer:
Nerve impulses travel through your nervous system from neurons to other neurons or body structures. A reflex is an involuntary response that occurs rapidly without conscious control. Touching something and pulling your hand away is an example of a response.

Answer:
A current of 1ma flows through a copper wire, how many electron will pass a given point in one second? 1 Coulomb = 6.24 x 10^18 electrons (or protons)/1Sec which is also equal to 1 Amp/1 Sec. 1mA is 1/1000th of 1A so only 1/1000th of 6.24 x 10^18 electrons will pass a given point in 1 Sec.
