The Mass of the barter and the ball is 3.1kg
Data Given;
- F = 1.1*10^-9N
- r = 0.76m
- G = 6.67*10^-11 m^3 kg^-1 s^-1
Assuming the barter and the ball have equal mass, we can apply gravitational force formula.
<h3>Gravitational Force</h3>

This is product of the mass of the two bodies and divided by the square of their distance apart.
Substituting the values into the formula

From the calculations above, the mass of the barter and the ball is 3.1kg

Answer:
the helis speed increased its speed by 35 m/s. Unless you are asking me what was the speed per second. if you were asking me for the speed per second then that would be a different answer
Explanation:
B. Because chemical changes (for example, burning turning something into ashes) can change it's appearance while physical changes (for example, crumpling a piece of paper) can aswell.
The second law of thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.
