Answer: 131.92 m
Explanation: The problem give above is a conversion problem. To convert any measurement from one unit to another, we need a relation for the original units to that of the desired unit. This relation is called the conversion factor. It is used by multiplying or dividing the factor depending on what is the unit of the original measurement. For this case, we need to convert from ft^2 to m^2. The conversion factor would be 1 foot is equal to 0.3048 m. So, we would be getting the square of the factor and then multiply to the original value.
1420 ft^2 ( 0.3048 m / 1 ft)^2 = 131.92 m
Answer:
see that the correct one is D
Explanation:
In this problem the satellite is subjected to the universal force of attraction
F = G M m / r²
using Newton's second law with centripetal acceleration you can find the angular velocity of the satellite
F = m a
F = m w² r
G M / r³ = w²
and w = 2π / T
In this case, the satellite is in a two-dimensional movement, where the free fall of the satellite is compensated by the horizontal displacement, for which it is always at a distance from the earth, remaining at the same point.
When reviewing the different statements we see that the correct one isD
The work done by along the given path <em>C</em> from <em>A</em> to <em>B</em> is given by the line integral,
I assume the path itself is a line segment, which can be parameterized by
with 0 ≤ <em>t</em> ≤ 1. Then the work performed by <em>F</em> along <em>C</em> is
Let's see
Now we know the formula of acceleration
Or
The electric flow is defined as the change of the charge in relation to the constant of the vacuum permittivity constant.
That is to say that mathematically this expression could be given as
Here,
= Electric Flux
q = Charge
= Vacuum Permittivity
Replacing with our values and solving to find q, we have,
Therefore the charge is enclose within the octahedron with a charge of
