Ive got a bunch so ill put it in seperate qs of 3 A cheetah runs at a speed of 27.6 m/s. If the cheetah runs for 9.30 s, what is the distance the cheetah runs? Show all your work.

3. A rifle fires a bullet toward a target 102 m away. If the bullet travels at a supersonic speed of 585 m/s, how long does the bullet take to reach the target? Show all your work.

. An airplane is waiting to take off on the runway at the airport. The plane is then cleared for take off and accelerates down the runway for 26.1 s to reach a 71 m/s lift off velocity. What was the airplane’s acceleration on the runway? Show all your work

What best describes a sonar wave? transverse and electromagnetic transverse and mechanical longitudinal and electromagnetic longitudinal and mechanical

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

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference
