Answer:
Force is work done divided by distance
Explanation:
Work done to an object is given as rhe product of force and diatance moved, hence expressed as W=Fd where F is the applied force in Newtons, d is diatance moved in meters and W is work. The relationship between force and distance then is found by making either F or d the subject hence
hence we can say that distance is given by dividing work by force or alternatively Force is relates to distance by dividing work done by distance. Both are correct.
Well, first of all, 10³⁰ kg is its mass, not its weight.
-- Density of anything is (its mass) divided by (its volume).
-- You know the white dwarf's mass.
-- The volume of any sphere is (4/3) (pi) (radius)³
-- The radius is 1/2 of the diameter.
-- Now you have the ball. Run with it.
I did it quickly and got (1.91 x 10¹²) kilogram/meter³ .
That may be wrong. You have to check it. And even
if it's correct, you probably want to express density in
units of gram/cm³ the way everybody always does.
Force equals mass time acceleration. Weight is a force and it can replace force in the equation. The acceleration would be gravity, which is an acceleration.
1.)
Fw (weight) = m (mass) · g (gravity, 9.8 m/s²)
Fw = m * 9.81 m/s²
560N = m · 9.81 m/s²
m ≈ 57.08 kg
2.)
d = 350 meters
t = 65 seconds
velocity = d/t
velocity = 350 meters / 65 seconds
velocity ≈ 5.38 meters/sec
3.)
Force = 35N
Distance = 2 meters
Work = Force · Distance
Work = 35N · 2 meters
Work = 70 J
