Gravitational pull between 2 objects is determined by which of the following?
2 answers:
Answer:
Both distance between and mass of the 2 objects
Explanation:
The gravitational pull between two objects is given by:
where
G is the gravitational constant
m1 is the mass of the first object
m2 is the mass of the second object
r is the distance between the two objects
From the formula, we see that the gravitational pull depends both on the distance between the two objects (r) and on their masses (m1, m2), so the correct answer is
Both distance between and mass of the 2 objects

Answer:
(a) 1 : 2
(b) same
Explanation:
Let the mass of puck A is m and the mass of puck B is 2 m.
initial speed for both the pucks is same as u and the distance is same for both is s.
let the tension is T for same.
The kinetic energy is given by
(a) As the speed is same, so the kinetic energy depends on the mass.
So, kinetic energy of A : Kinetic energy of B = m : 2m = 1 : 2
(b) A the distance s same so the final velocities are also same.
Answer:
304.86 metres
Explanation:
The x and y cordinates are and
respectively
The horizontal distance travelled,
Making t the subject,
Since , we substitute t with the above and obtain
Making d the subject we obtain
d=304.8584
d=304.86m
