An airplane traveling 1000 m above the ocean at 140 km/h is going to drop a box of supplies to shipwrecked victims below.


(b) What is the horizontal distance between the plane and the victims when the box is dropped?

Answers

Answer 1

Answer:

Horizontal distance = 555.74 m

Explanation:

Given the following data;

Height = 1000m

Horizontal velocity = 140km/h

First of all, we would convert the unit of the velocity to meters per seconds;

V = (140 * 1000)/60*60

V = 140000/3600 = 38.89m/s

To find the time, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

We know that acceleration due to gravity, g is equal to 9.8m/s²

Initial velocity, u = 0

Substituting into the equation, we have;

[tex] 1000 = 0(t) + \frac {1}{2}*9.8*t^{2}[/tex]

[tex] 1000 = 0 + 4.9*t^{2} [/tex]

[tex] 1000 = 4.9*t^{2} [/tex]

[tex] t^{2} = \frac {1000}{4.9} [/tex]

[tex] t = \sqrt{204.08}[/tex]

Time, t = 14.29 secs

To find the horizontal distance;

Speed = distance/time

[tex] Horizontal \; distance = horizontal \; velocity * time [/tex]

[tex] Horizontal \; distance = 38.89 * 14.29[/tex]

Horizontal distance = 555.74 m

My guess would be "dark adaptation"

Dark adaptation is doing each of the following concepts explain Melly's actions. Hence, option B is correct.

What is Dark adaptation?

Dark adaptation, thus, refers to the process by which, after exposure to strong light, the eye regains its sensitivity in the dark. Aubert was the first to calculate the threshold stimulation of the eye in the dark in 1865 by calculating the electrical current required to just barely make the glow on a platinum wire visible.

After being exposed to light, a process known as dark adaptation causes our eyes to adjust to darkness. When going from a bright, sunny environment outside to a rather dark interior setting, for example, it can be difficult to see at first. But as time goes on, our eyes recover and get more sensitive to the dim interior light.

Thus, option B is correct.
