The radius of the Earth is about 3,960 miles.
That's how far the center of the Earth is straight down under your feet.
It's farther than the distance all the way across the USA, from New York
to Los Angeles. It's like the distance from London (England) to Chicago.
If you drill absolutely straight and aim straight down, that's how far
you need to drill to reach the center. Unfortunately, your drill will melt
long before you get there.
The longest hole ever drilled into the Earth (so far) is the Sakhalin-I Oduptu Well,
drilled by Russia into the sea-bottom in 2011.
That hole is 40,502 feet ... roughly 7.67 miles, or about 0.0019 of the distance
to the center of the Earth. You can see that we still have quite a long way to go !
Answer:
a = v²/r
Explanation:
The acceleration of a body moving in a circular path is known as the centripetal acceleration. This is the acceleration of a body that keeps the body within the circular path. It is written in terms of the linear velocity v and the radius of the circle of rotation as shown;
a = v²/r where
v is the linear velocity
r is the radius
a is the centripetal acceleration
Answer:
λ = 1.4 × 10^(-7) m
Explanation:
We are given;
distance of eye piece from the source;D = 1.5 m
distance between the virtual sources;d = 7.5 × 10^(-4) m
To find the wavelength, we will use the formula for fringe width;
X = λD/d
Where X is fringe width, λ is wavelength, while d and D remain as before.
Now, fringe width = eye-piece distance moved transversely/number of fringes
Eye piece distance moved transversely = 1.88 cm = 1.88 × 10^(-2) m
Thus,
Fringe width = (1.88 × 10^(-2))/10 = 1.88 × 10^(-3) m
Thus;
1.88 × 10^(-3) = λ(1.5)/(7.5 × 10^(-4))
λ = [1.88 × 10^(-3) × (7.5 × 10^(-4))]/1.5
λ = 1.4 × 10^(-7) m
Answer:
This a pure case of conflict of interests between the interest of the shareholders who are the original owners of the company and management's interest in earning much more,even if it at the expense of the shareholders.
Explanation:
Management is the entrusted with the day to day affairs of corporations.In carrying out their duty,they must have at the back of their minds that maximization of shareholder's wealth is of top priority.
However.some management teams in a bid to gain undue advantage set their remuneration below reasonable levels.
Ultimately,when this happens, their duty to watch over the investment of shareholders clashes with their interest for personal gains.
