Which of the following statements are true? Check all that apply. Check all that apply. The gravitational force between two obje
2 answers:
Explanation:
The gravitational force acting between two masses is given by :;
Where
G is the universal gravitational constant
m₁ and m₂ are masses
d is the distance between masses
The correct statements are as follows :
1. The gravitational force between two objects is inversely proportional to the square of the distance between the two objects.
2. The gravitational force between two objects is proportional to the product of the masses of the two objects.
Hence, this is the required solution.

Answer:
Hits per second=199 hit/s
Explanation:
#Given the angular velocity, , radius of the record
and the distance between any two successive bumps on the groove as
.
The linear speed of the record in meters per second is:
#From above, if the bumps are uniformly separated by 1m, then the rate at which they hit the stylus is:
Hence the bumps hit the stylus at around 199hit/s
