Answer:
The answer of the question is False
Answer:
x = 727.5 km
Explanation:
With the conditions given using trigonometry, we can find the tangent
tan θ = CO / CA
With CO the opposite leg and CE is the adjacent leg which is the distance from the Tierral to Sun
D =150 10⁶ km (1000m / 1 km)
D = 150 10⁹ m.
We must take the given angle to radians.
1º = 3600 arc s
π rad = 180º
θ = 1 arc s (1º / 3600 s arc) (pi rad / 180º) =
θ = 4.85 10⁻⁶ rad
That angle is extremely small, so we can approximate the tangent to the angle
θ = x / D
x = θ D
x = 4.85 10-6 150 109
x = 727.5 103 m
x = 727.5 km
Answer:
a)
b)
c) The estimate is low.
Explanation:
a) Using the energy conservation we have:
we have kinetic energy intially and gravitational potential energy at the maximum height.
b) We can use the equation of the gravitational force
(1)
We have that:
(2)
at the surface G will be:
Now the equation of an object at a distance x from the surface.
is:
Using that dv/dt is vdx/dt and integrating in both sides we have:
c) The difference is:
So the percent difference will be:
The estimate is low.
I hope it helps you!
Answer:
empty space
Explanation:
A hydrogen atom is about 99.9999999999996% empty space. All atoms have electrons, protons, neutrons, electrons and a nucleus.
