Answer:
Yes
Explanation:
There will be a force because the large metal sphere is polarized when the rod is placed close to it, this happens because the metal sphere has free electrons and they will be attracted by the positively charged rod, the sphere will remain neutral as a whole (the same number of negative and positive charge), but a portion of the sphere will become more positive and the other more negative, creating this force.
Answer:
We will use Potential Energy Formula
Potential Energy = mass × gravitation × height
PE = 0,55 × 10 × 4
PE = 22 J (A)
For the lever to work, your force multiplied by the input arm should be equal to the rock's weight multiplied by the output arm. Therefore:
500I = 2000O
I/O = 4
The input and output arms should be in the ratio 4 : 1
Explanation:
everything can be found in the picture
Among these, the greatest impact would have to be Newton's first law, the law of gravity. All of the planets stay in their own orbits, even if their orbits are not exactly perfect. This is done because of the sun's gravitational force, which keeps all of the planets in the solar system revolving around it.
