Answer:
8m/s^2
Explanation:
<em>Acceleration</em><em>=</em><em>initial </em><em>velocity</em><em>-final </em><em>velocity</em><em>/</em><em>time</em>
<em>initial</em><em> </em><em>velocity(</em><em>u)</em><em> </em><em>is </em><em>3</em><em>2</em><em> </em><em>final </em><em>velocity</em><em> (</em><em>v)</em><em> </em><em>is </em><em>9</em><em>6</em>
<em>therefore</em>
<em>a=</em><em>9</em><em>6</em><em>-</em><em>3</em><em>2</em><em>/</em><em>8</em>
<em>a=</em><em>8</em><em>m</em><em>/</em><em>s </em><em>squared</em>
<em>hope </em><em>it </em><em>helps</em>
8.34 m/s

Answer:
a)
b)
Explanation:
We are comparing two wavelengths with the radius and diameter constant, and if we want to compare it, we need to use the following formula:
Where represent the angular resolution and the wavelength.
So if we have a fixed resolution and wavelength 1 and we want to find the resolution for a new condition we can solve for and we got
Part a
For this case the subindex 1 is for the color red and we know that:
And the angular resolution for the color red is specified as
And for the infrared case we know that , so if we replace we got:
Part b
For this case the subindex 1 is for the color red and we know that:
And the angular resolution for the color red is specified as
And for the ultraviolet case we know that , so if we replace we got:
Answer:
a. abyssal plain far from a continent
Explanation:
- The sediments of the abyssal plains contain of the abundant mineral resources and notably polymetallic nodules and re also called the manganese nodules and these are on the shape of potatoes and distributed at the depths of about 4000 meters.
- <u>And they lie at the international line of the pacific oceans stretching in an area of 118°–157°, and from 9°–16°N, that is 3 million m square is currently under the noddle exploration and discovery.</u>
Here,
m=80 kg
R= 6.4*10^6 m
and t=24*3600=86400 s
Centripetal acceleration:
a=ω²r
=(2
/86400)^2 * 6.4*10^6
=0.034 m/s²
