Gravity is ____________________ to the distance between and difference in mass between two objects

Physics

Orlov [11]3 years ago

Explanation:

Force of gravity is the force which attracts objects along with its mass towards the Earth or ground.

Mathematically,       F = \frac{Gm_{1}m_{2}}{r^{2}}

where                F = force of gravity

                         G = gravitational constant

                          m_{1} = mass of object 1

                          m_{2} = mass of object 2

                          r = distance between the given masses

Therefore, more is the mass of object more will be the force of gravity. Whereas more is the distance between objects or masses then less will be the force of gravity.

Hence, we can conclude that gravity is inversely proportional to the distance between masses and directly proportional to the masses of objects.

If a nearsighted person has a far point df that is 3.50 m from the eye, what is the focal length f1 of the contact lenses that t
Anastaziya [24]

Answer:

f1 = -3.50 m

Explanation:

For a nearsighted person an object at infinity must be made to  appear  to be at his far point which is 3.50 m away. The image of an object at infinity must be formed on the same side of the lens as the object.

∴ v = -3.5 m

Using mirror formula,

i/f1 = 1/v + 1/u

Where f1 = focal length of the contact lens, v = image distance = -3.5 m, u =         object distance = at infinity(∞) = 1/0

∴ 1/f1 = (1/-3.5) + 1/infinity

  Note that, 1/infinity = 1/(1/0) = 0/1 =0.

∴ 1/f1 = 1/(-3.5) + 0

  1/f1 = 1/(-3.5)

Solving the equation by finding the inverse of both side of the equation.

∴ f1 = -3.50 m

 Therefore a converging lens of focal length  f1 = -3.50 m

would be needed by the person to see an object at infinity clearly
