One of Saturns moons has an orbital distance of 187 times 10

One of Saturn\'s moons has an orbital distance of 1.87 times 10^8 m. The mean orbital period of this moon is approximately 23 hours. Use this information to estimate a mass for the planet Saturn. During a rain storm, rain comes straight down with a velocity V_i = -15 m/s and hits the roof of a car perpendicularly. The mass of the rain per second that strikes the roof is 0.060 Kg every second. Assuming that the rain comes to rest upon striking the car (V_F = 0 m/m) find the average force exerted by the rain on the roof during a 3 second time Interval. A 1.5 kg object is pushed to the right with a net force of 60N. If a 5 kg object experiences the same acceleration, how much force is it being pushed with? On a hot summer day (30 degrees Celsius), a posky little mosquito produced its warning sound near your ear. The sound is produced by the beating of its wings at a rate of about 600 wing beats per sound. What is the frequency in Hertz of the sound wave? What is the wavelength of the wave? A man pushes a 50N box across a level floor at a constant speed of 2.0 m/s for 10 s Find the average power output by the man. A motorcyclist is trying 10 leap across a canyon by driving horizontally of the cliff that is 70.0 m high at 38.0 m/S Ignoring air resistance. use energy conservation to find the speed with which the cycle strikes the ground at a height of 35.0 m on the other side of the canyon You do not need to know how wide the canyon 1st In a serious accident, a nuclear power plant s reactor vessel cracks and all of the cooling water drains out. Although nuclear fission stops, radioactive decay continues to heat the reactor\'s 2.5 times 10^5 kg uranium core at a rate of 120 Mega-Watts. Once the core reaches its melting point, how much energy will it take to melt the core? How long will the molting take? Use the attached table.. What is a black hole? What is a singularity? If the earth had twice its present radius and twice its present mass, what would happen to your weight? Explain. What is the relationship between the radius of orbit of a satellite and its period ? A horse pulls on a create with a 1.000 N force, causing it to move at constant velocity What is the acceleration of the cart? A 44-kg child steps onto a scale What is the magnitude of the force that the scale exerts on the child? What is resonance? Discuss examples of how resonance can be useful and harmful Suppose in a restaurant your coffee is served about 5 or 10 minutes before you are ready for it If you want the coffee to be as hot as possible when you drink it. should you pour to the room temperature cream right away or when you are ready to drink the coffee? Advertisements for a toy ball once stated that it would rebound to a height greater than the height from which it was dropped Is this possible? Why or why not?

Solution

Please upload each question seperately. Based on Chegg guidelines only one question with atmost 4 subparts can be answered at once. I will solve problem 3 for you, since it is conceptual in nature.

F = ma (Newton\'s second law)
60 = 15a
a = 4 m/s2

F = ma
F = 5*4 = 20 N
