At a particular instant the magnitude of the momentum of a planet is 2.25 times 1029 kg m/s, and the force exerted on It by the star It is orbiting is 9.2 times 1022 N. The angle between the planet's momentum and the gravitational force exerted by the star is 129degree. What is the parallel component of the force on the planet by the star? What will the magnitude of the planet's momentum be after 8 h? (Enter your answer to at least four significant figures.)

Using a pedometer, you walk 3000 steps in 20 minutes, so your speed is 150 steps/min. each of your steps is 0.7 m long. what is your speed? 150 steps/min=/s=/h

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

What conclusion can be made based on the temperature of soil when the light hits the soil at 0°, 45°, and 90° angles in section 2 of the experiment? did your results support your hypothesis? why or why not?
