Explanation:
M₂ = Fr²/GM₁
M₂ = [(132N)(.243m)²]/[(6.67*10^-11N*m²/kg)(1.175*10^4kg)]
M₂ = (7.79N*m²)/(7.84*10^-7N*m²)
M₂ = 9.94*10^6 kg
Answer:
A) do a greater amount of work than the amount of work done on the machine
Explanation:
By the principle of conservation of energy, energy can never be created or destroyed.
To do more work by a machine than the amount of work done on the machine is impossible because to do so machine will have to create energy within itself which violates the principle of conservation of energy.
Extra bit,
These kind of machine are defined as perpetual-motion machines and there are many attempts in history to create one such device but all were failed.
Answer:
C) unbalanced
Explanation:
Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
Explanation:
Without the metric system, we'd have a different International System of Units, the metric system is important because 1mm is 0.1cm, 1 cm is 0.01m, with the imperial system the conversion is tedious. The most important feature of the metric system is its base in scientific fact and repeatable standards of measurement
The force exerted between 2 point charges is directly proportional to the product of their strengths, is inversely proportional to the square of the distance between them and is inversely proportional to the absolute permittivity of the surrounding mediums.
I hope that helps somewhat, I'm only kind of sure that could be correct
