What is the relationship between distance and mass in termsnof gravitational force

Physics

Softa [21]3 years ago

There is no relationship between distance and mass.  But the gravitational force
between two objects is related to both of those quantities.

-- The gravitational force between two objects is directly proportional to
the product of their masses.

-- The force is also inversely proportional to the square of the distance
between their centers.

Well,

I'm pretty sure you wanted how the distance between objects or the mass of two objects affects the gravitational force.

The Second Universal Law of Gravitation states that the gravitational force between two objects is directly proportional to the mass of the two objects. (mass)

The Third Universal Law of Gravitation is a bit more complex: The gravitational force between two objects is inversely proportional to the square of the distances between those two objects.  This means that if the initial distance between two objects is 1 unit, and the initial gravitational force between those two objects is 1 unit, and then the distance between the two objects is halved, then the gravitational force will increase by the square of 2, or 4 units.  So the final distance will be 0.5 units and the final gravitational force will be 5 units.

A

An object at rest will remain at rest unless acted on by a force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by a force.

A tire swing hanging from a branch reaches nearly to the ground. How could you estimate the height of the branch using only a st
blagie [28]

Answer:

A stop watch measures time and the number of seconds making an osculation is the period T

Which is T = 2π√(L/g)........solving for L (the length of the pendulum),

Then the L = T²x g/( 4πr²) substitute and then u find length or height of the swing

A segment A of wire stretched tightly between two posts a distance L apart vibrates in its fundamental mode with frequency f. A
____ [38]

Answer:

option (c)

Explanation:

Fundamental frequency of segment A = f

Second harmonic frequency of B = fundamental frequency of A .

Tension in both the wires is same and the mass density is also same as the wires are identical.

fundamental frequency of wire A is given by

f=\frac{1}{2L_{A}}{\sqrt{\frac{T}{m}}}    .... (1)

Second harmonic of B is given by

f=\frac{2}{2L_{B}}{\sqrt{\frac{T}{m}}}    .... (2)

Equation (1) is equal to equation (2), we get

\frac{1}{2L_{A}}=\frac{2}{2L_{B}}

L_{B}=2L_{A}

So, LB = 2 L

Thus, the length of wire segment B is 2 times the length of wire segment A.

What is the velocity of a car that travelled a total of 75 km north in 1.5 hrs?
AURORKA [14]
V=d*t
Since d=75km=75000m
t=1.5h=3600*1.5= 5400s
=>V=75000*5400
=405000000m/s=4.05*10^8m/s

A ball is thrown upward from the top of a building at an angle of 30.0° to the horizontal and with
Ray Of Light [21]

Answer:

See below

Explanation:

Vertical position = 45 +  20 sin (30) t  - 4.9 t^2

 when it hits ground this = 0

               0 = -4.9t^2 + 20 sin (30 ) t + 45

                0 = -4.9t^2 + 10 t +45 = 0     solve for t =4.22 sec

  max height is at  t= - b/2a = 10/9.8 =1.02

     use this value of 't' in the equation to calculate max height = 50.1 m

      it has  4.22 - 1.02 to free fall = 3.2 seconds free fall

           v = at = 9.81 * 3.2 = 31.39 m/s VERTICAL

      it will <u>also</u> still have horizontal velocity =  20 cos 30 = 17.32 m/s

        total velocity will be sqrt ( 31.39^2 + 17.32^2) = 35.85 m/s

Horizontal range = 20 cos 30  * t  =  20 *  cos 30  * 4.22 = 73.1 m
