The correct answer is:
Product of their masses
In fact, the gravitational pull between two objects is given by:
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the distance between the centres of the two objects
From the equation, we immediately see that the gravitational attraction is directly proportional to the product of the masses.
Answer:
p = 22.5 cm
Explanation:
For this exercise we must use the equation of the constructor
where f is the focal length, p and q are the distance to the object and the image respectively.
Let's start with the far point, the object is very far away (p = ∞) and the image must be formed at the far point of view of the person q = 45.0 cm
since the image is on the same side as the object according to the sign convention the distance is negative
f = -45.0 cm
now let's use the near point (q = 15.0 cm) at what distance the object should be
1 / p = 1 / -45 - 1 / -15
1 / p = -1/45 + 1/15
= 0.0444
p = 22.5 cm
this is the closest distance you can see an object clearly
