10. A woman has a mass of 55 kg on Earth. What would be the woman's weight on the moon where the acceleration due to gravity is 1.67 m/s??
11.A man has a mass of 80 kg on Earth. What is the man's weight on Earth in Newtons?
12. A man has a mass of 80kg on Earth. What is the man's weight on Mars where the
acceleration due to gravity is 3.7 m/s??
13.A man has a mass of 80 kg on Earth. What is the man's mass on Mars where the acceleration
due to gravity is 3.7 m/s2?
14. A probe weighs 980 N on Earth. What is the probe's mass?
15. The same 980 N probe leaves Earth. What is the probe's weight when it reaches the surface
of Mars where the acceleration due to gravity is 3.7 m/s??

Comedians like to joke that the reason we haven’t been visited by intelligent life from elsewhere in the universe is that aliens have been monitoring earth’s broadcasts of intellectually embarrassing tv programs, like gilligan’s island, fear factor, the jersey shore, and the jerry springer showand so consider us far too primitive to merit a visit. let’s check the assertion that aliens could have been receiving them. tv programs are broadcast at a frequency of about 100mhz with about 100kw of total power in 30frames per second, which emanatesroughly uniformly in all directions. assume that interstellar space transmits these broadcasts without attenuation. no matter how smart they are, aliens would require at least one photon per frame to interpret our signals. findthe number of photons per unit time per unit area reaching a receiver on a possible planet in the nearest star system, which is about 4 light-years away (a light-year is the distance light travels in a year). if aliens aimed a receiver or detector directly at earth, how big (in diameter) would it have to be to receive a photon per frame

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

What’s #16 asking me and how do i solve it?
