The additional information needed to determine the velocity of the elevator is the direction of motion

Explanation:

The difference between speed and velocity is the following:

- Speed is a scalar quantity that gives a measure of how fast an object is moving, regardless of its direction. It is calculated as the ratio between the distance covered and the time taken:

$speed = \frac{distance}{time}$

- Velocity is a vector quantity, defined as the ratio between the diplacement of the object and the time taken:

$velocity = \frac{displacement}{time}$

Being a vector, velocity has both a magnitude (which is the speed) and a direction.

Therefore, in order to determine the velocity of the elevator, we must know:

- Its speed (which we alreay know, 4.5 m/s)

- The direction of motion

So the missing information is the direction of motion.

Answer:

1362000 kgm/s

Explanation:

So the total mass combination of the plane and the people inside it is

M = 35000 + 160*65 = 45400 kg

After 15 seconds at an acceleration of 2 m/s2, the plane speed would be

V = 2*15 = 30 m/s

So the magnitude of the plane 15s after brakes are released is

MV = 45400 * 30 = 1362000 kgm/s

You are wearing earbuds or headphones to listen to your music but your family members can hear it as well. They tell you that it

allsm [11]

If it’s loud enough for your family to hear it, it’s best you turn it down. It could cause permanent damage to your ear drums if it’s loud enough and you could start to lose your hearing. So if your family were to tell you to turn it down, you should probably just turn it down!

maw [93]

V^2=u^2 +2aS
U is found first by considering that first 8 secs and using v=u+at. {different v and u though}

V=-u+gt.
Magnitude of u = magnitude of v if there is no resistance ( because the conservation of energy says the k. E. must be the same when it passes you as when it left your hand).... up is negative here, down is positive.
V+v=gt
2v= g x 8
V=4xg.= the initial velocity for the next calculation
V^2=(4g)^2+(2xgx21)

So v can be calculated.

In order for a person to "see" an object, light waves pass through the ___________.

spayn [35]

I think the correct answer from the choices listed above is the first option. In order for a person to "see" an object, light waves pass through the cornea. The cornea is the transparent layer forming at the front of the eye. Hope this answers the question. Have a nice day.
