Question 4 of 25 Two asteroids with masses 3.71 x 10 kg and 1.88 x 10 kg are separated by
a distance of 1,300 m. What is the gravitational force between the asteroids?
Newton's law of gravitation is Fgravity - Cmm The gravitational constant
Gis 6.67 x 101 N-mIkg²
OA. 2.75 x 107 N
B. 4.13 x 103 N
OC. 3.58 x 104N
D. 2.04 x 1033 N

Iron reacts with sulfur to form iron sulfide. if 60 grams of iron reacts with sulfur to produce 90 grams of iron sulfide, how much sulfur has been used in the chemical reaction?

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

=force × distance a. work b. velocity c. pressure d. momentum
