Answer:
<h2>4.6 m/s²</h2>
Explanation:
The acceleration of an object given it's velocity and time taken can be found by using the formula
<h3>
</h3>
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
Since the body is from rest u = 0
From the question we have
We have the final answer as
<h3>4.6 m/s²</h3>
Hope this helps you
Answer:
Hi myself Shrushtee.
Explanation:
Artificial gravity is a must for any space station if humans are to live there for any extended length of time. Without artificial gravity, human growth is stunted and biological functions break down. An effective way to create artificial gravity is through the use of a rotating enclosed cylinder, as shown in the figure. Humans walk on the inside edge of the cylinder, which is sufficiently large (diameter of 2235 meters) that its curvature is not readably noticeable to the inhabitants. (The space station in the figure is not drawn to the scale of the human.) Once the space station is rotating at the necessary speed, how many minutes would it take the space station to make one revolution?
The distance traveled by the man in one revolution is simply the circumference of the space station, C = 2p R. From this result, you should be able to deduce the time it takes for the space station to sweep out a complete revolution.

<span>The correct answer is C. 60. A more precise answer would be around 70, but this is the closest one we have. As a matter of fact, 50% of the net income is made by only 5% of companies, while the remaining US corporations raise the bar to around 70. These 5% are mostly conglomerates that deal in all areas of business, from food to cosmetics to furniture.</span>
Speed (v) = wavelength (λ) x frequency (f)
If speed is constant and frequency is reduced by factor of 3, you will need to increase wavelength by the same factor so that your changes reduce out.
Answer is A.
