Need help with #10 and #21 An Astronaut mass is 100 kg on the Earth. Earth's gravity is approximately 10 m/sec².a) What is the Astronauts weight on the Earth?b) If the gravity of the moon is 1/6 that of Earth. What would the Astronauts weight be on themoon?1000 kg, 166 kg100 kg, 200 kgO 1000 newtons, 166 NewtonsO 100 Newtons, 16 Newtons The largest astronomical refractor has an aperture of about 1 meter. What is the main reason why itwould be impractical to build a larger refractor with twice this aperture.O Glass can only be cast in meter size diametersO Secondary reflections ruin the image for larger diametersO The glass is strong enough, but the steel tube sagsO Glass sags under it own weight

Given data: Mass (m) = 100 kg ge = 10 m/s2 gm = (1/6)ge = 10/6 m/s2

Answered: An Astronaut mass is 100 kg on the…

Suppose astronomers find an earthlike planet that is twice the size of Earth (that is, its radius is twice that of Earth’s). What must be the mass of this planet such that the gravitational force (Fgravity) at the surface would be identical to Earth’s?
Respond to each statement, true or false: (a) No force of gravity acts on an astronaut in an orbiting space station. (b) At three Earth radii from the center of Earth, the acceleration of gravity is one-ninth its surface value. (c) If two identical planets, each with surface gravity g and volume V, coalesce into one planet with volume 2V, the surface gravity of the new planet is 2g. (d) One kilogram of gold would have greater value on Earth than on the Moon.
Check Your Understanding Earth exerts a tidal force on the Moon. Is it greater than, the same as, or less than that of the Moon on Earth? Be careful in your response, as tidal forces arise from the difference in gravitational forces between one side and the other. Look at the calculations we performed for the tidal force on Earth and consider the values that would change significantly for the Moon. The diameter of the Moon is one-fourth that of Earth. Tidal forces on the Moon are not easy to detect, since there is no liquid on the surface.
(a) What is the approximate force of gravity on a 70kg person due to the Andromeda galaxy, assuming its total mass is 1013 than of our Sun and acts like a single mass 2 Mly away? (b) What is the ratio of this force to the person's weight? Note that Andromeda is the closest large galaxy.

Assume that the gravity of Mars is 5 times that on the earth. What mass would an object have on Mars if its mass is 15kg on earth? a) 75kg b) 25kg c) 60kg d) 15kg
You’re involved in the design of a mission carrying humans to the surface of the planet Mars, which has a radius 3.37x106m and a mass of 6.42x1023 kg. The earth weight of the Mar’s lander is 39,200 N. Calculate its weight and the acceleration due to Mar’s gravity at 6.0 x 106 m above the surface of Mars.
