Falling from an airplane.
It would be hard so many factors play a role in this angle kinetic potential energy gravity positioning height weight etc.to keep something as described moving as long as possible you'd have to build it heavily enough to balance out the momentum at each climax of the swing to balance with the gravitational pull of the earth core.I'd use a material such as copper for the variable.Also the weight distribution on the variables base plays a role.Take all the into account and experiment for a while!maybe one day you could find the right proportions in every role for kinetic potential gravitational momentum and weight to keep it going forever. As said alotta factors play a huge role in this experiment <span />
Answer:
80.4m
Explanation:
The equation for the hight of flight is:
<span>G = gravitational constant
M = mass of the earth
R = radius of orbit of a satellite
r = radius of orbit of a second satellite
v = speed of the satellite
P = period of a satellite
p = period of a second satellite
Equate gravitational acceleration with centripetal acceleration
g = G*M/R^2 = v^2/R
Express the orbital speed in terms of the orbit circumference and period
v = 2*pi*R/P
And insert the expression for v into the first equation
G*M/R = 4*PI^2*R^2/P^2
G*M/R^3 = 4*pi^2/P^2
R^3/P^2 = 4*pi^2/(G*M) = constant = C
We can do the above since G and M are constants for all earth orbits
So we can write a second equation of the same form for another satellite and equate to get:
R^3/P^2 = r^3/p^2
r^3 = R^3*p^2/P^2
r = R*(p^2/P^2)^(1/3)
For the second satellite we have p = 8*P
r = R*(8^2)^(1/3) = R*(64)^(1/3) = 4*R</span>
Answer:
C. There is a net force on the box.
Explanation:
If the box was stationary, sitting on the roof, the correct answer choice would be A. In this scenario, the box is fallign downward, meaning that there is a net force pushing the box downward.
