Answer:
that initially the weather vane was at rest, by this load that remained on the pole it would begin to move.
Explanation:
Let us carefully analyze the situation, when the bar is facing the index post a load of equal magnitude, but opposite sign on its surface, these two charges are in balance; When the hand touches the pole, it creates a path to the ground where the charges that were induced on the pole can be balanced with the charge coming from the ground, leaving a zero charge on the pole.
Now if the hand is removed, there can be no exchange of charges with the earth. When the bar is removed, the induced loads are redistributed in the post, but the excess loads that came from the earth that have the same value and are of a sign opposite to the induced ones remain, you want to sign that they are of the same sign as the charges of the bar.
In summary, after the process, the post has a load of equal magnitude and sign (negative) that of the bar.
If we assume that initially the weather vane was at rest, by this load that remained on the pole it would begin to move.
Muscular strength is a measure of how much force you can exert in one repetition. Muscular endurance refers to the ability to perform a specific muscular action for a prolonged period of time.
Answer:
D
Explanation:
The forces have the same magnitude (3N), but different directions. So they are different.
Answer: Gravitational force
Explanation:
The law of universal gravitation states that the force of attraction (F) between two bodies is directly proportional to their masses m1 and m2, and inversely proportional to the square of the distance (R) seperating them.
Thus, it is expressed mathematically as:
F = Gm1m2/R²
where,
- G is the gravitational constant with a value of 6.7 x 10^-11 Nm2/kg2
- F is the Gravitational force (unit is Newton)
- m1 and m2 are the masses of the two bodies (unit is kilograms)
- R is the distance seperating the two bodies. (unit is metres)
Thus, the formula f=G(m1m2)/R² help us find the gravitational force.
