Answers
Answer:
1.308104*10^-8 N (1.31*10^-8 N when rounded)
Explanation:
The mathematical formula for gravitational force is F = G Mm /r^2 where G is the gravitational constant which is measured 6.674 *10^ − 11 N (m/kg) ^2.
Since both objects, M and m, have masses of 70kg and the distance r is 5 meters, then we can plug these values into the formula:
F=GMm/r^2
F=(6.674*10^-11)(70)(70)/(5^2)
F=(6.674*10^-11)(4900)/25
F=(3.27026*10^-7)/25
F=1.308104*10^-8
So the gravitational force of attraction between the two objects is 1.308104*10^-8 N.

Does the mass of the objects you are charging influence the amount of electric force created in an electric field?
Answers
Explanation:
Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.
Why does an increase in temperature result in an increase in reaction rate?
Answers
Answer:
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.
Answer:
When we increase the temperature in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases collision between the particles and the rate of reaction.

At 10°C, the gas in a cylinder has a volume of 0.250 L. The gas is allowed to expand to 0.285 L.
What must the final temperature be for the pressure to remain constant? (Hint °C + 273 = K.)
282 K
284 K
323 K
248 K
Answers
We know that we want P1=P2 so the pressure will remain constant, so we can say that: P1V1T1=P1V2T2
Plug in the values we know: P1⋅0.250L283K=P1⋅0.285LT2
(Remember that temperature must be done in Kelvin.)
Cross multiply: T2⋅P1⋅0.250L=283K⋅P1⋅0.285L
Divide both sides by P1.
T2⋅0.250L=283K⋅0.285L
T2=283K⋅0.285L0.250L
T2=323K
(This is also 50˚C.)
(Answer is 323k)
