During the formation of the Solar System, smaller particles in the solar nebula combined to form planetesimals, some of which pr

ovided the building blocks for planets. The majority of planetesimals did not become planets, however, and some of them remain in the Solar System today as debris left over from the time of planet formation. Asteroids are a special class of planetesimals that orbit around the Sun. Choose all of the statements below that match your observations of asteroids.
Choose one or more:
A. There are clumps of asteroids that exist at particular spots in Jupiter's orbit.
B. Some asteroids cross Earth's orbit as they orbit around the Sun.
C. All of the asteroids exist in a region between Jupiter and Mars.
D. Asteroids have been discovered as far out as Pluto.
E. The majority of asteroids exist in a region between Jupiter and Mars.
F. The majority of asteroids exist inside of Mars' orbit.
G. Asteroids are randomly distributed throughout the Solar System.

The escape velocity at the surface of Earth is approximately 11 km/s. What is the mass, in units of ME (the mass of the Earth),
SVETLANKA909090 [29]

Answer:11 km/s

Explanation:

Given

Escape velocity at the surface of earth is 11 km/s

Escape velocity is given by

V_e=\sqrt{\frac{2GM}{R}}

Escape velocity at the surface of earth

11=\sqrt{\frac{2GM}{R}}--------------------1

If Escape velocity is three times and the radius is also the three times

V_e_2=\sqrt{\frac{2G(3M)}{3R}}

V_e_2=\sqrt{\frac{2GM}{R}}=V_e

i.e. V_e_2=11 km/s

What is the passengers velocity on the vertical drop of the tower of terror at Disney world if the distance for the drop is 50m,
andrey2020 [161]

Assuming constant acceleration due to gravity of a=9.8\,\dfrac{\mathrm m}{\mathrm s^2}, and assuming the passengers start at rest, so that v_0=0\,\dfrac{\mathrm m}{\mathrm s}, we have

v=v_0+at\implies v=\left(9.8\,\dfrac{\mathrm m}{\mathrm s^2}\right)(5.5\,\mathrm s)=53.9\,\dfrac{\mathrm m}{\mathrm s}

or 54 m/s if taking significant digits into account.
