Part b suppose the magnitude of the gravitational force between two spherical objects is 2000 n when they are 100 km apart. what is the magnitude of the gravitational force fg between the objects if the distance between them is 150 km ? express your answer in newtons to three significant figures. hints fg = 889 n submitmy answersgive up correct significant figures feedback: your answer 890 n was either rounded differently or used a different number of significant figures than required for this part. part c what is the gravitational force fg between the two objects described in part b if the distance between them is only 50 km ?

The formula for gravitational force is:

F = G m1 m2 / r^2

where G m1 m2 are constants, therefore:

F r^2 = constant

 

Part b. Given F1 = 2000 N, r1 = 100 km

Find F2 = ?, r2 = 150 km

 

(2000 N) * (100 km)^2 = F2 * (150 km)^2

F2 = 888.89 N

 

 

Part c. Given F1 = 2000 N, r1 = 100 km

Find F2 = ?, r2 = 50 km

 

(2000 N) * (100 km)^2 = F2 * (50 km)^2

F2 = 8000 N

The pitch of a sound come from the frequency of the soundwave, soundwaves that have bigger frequencies sound with a high pitch and soundwaves with less frequencie have low pitch.
