Two charges q1 and q2 are separated by a distance, d, and exert a force, F, on each other.Which best represents the new force F′ if q1 is tripled?

Answers

Answer 1

Answer:

If the charge q₁ is tripled then the force between the charged becomes 3 times the original charge.

Explanation:

Given:

Distance between the two charges = r

The force between two charges is given by:

$F_1 = k(q_1q_2)/(r^2)$

If q₁ is tripled, then the force F becomes:

$F_2 = k((3q_1)Xq_2)/(r^2)$

$(F_2)/(F_1) = (3q_1q_2)/(r^2) X (r^2)/(q_1q_2)\n\nF_2 = 3F_1$

Therefore, if the charge q₁ is tripled then the force between the charged becomes 3 times the original charge.

Answer 2

Answer:

Answer:

F′ = 3 F

How does the mass of an object affect its acceleration during a freefall?

Answers

There is a big misconception about this but I will try to clear it up:
Think about this, if you drop a feather and a marble from the same beginning point then they will both fall at the same rate. This is because, mass doesn't affect the speed of falling objects, however, if there are other factors involved other than gravity then the answer may vary.

Saturated fats that are found in avocados are good and should not be limited. True False

Answers

Answer;

The above statement is False

Explanation;

Saturated fats are types of fats that lacks double bonds or triple bonds between any two carbon atoms because they are saturated with hydrogen molecules.
Saturated fats should be limited at all costs. Eating foods with saturated fats raises the amount of cholesterol in the blood which may increase the risk of heart disease and stroke.
Avocados contain over 75% fat that is unsaturated or the good fats, and the rest are unsaturated or the bad fats. Therefore, saturated fats found in avocados are not good and should be limited.

Examine the circuit. Pretend you are an electron flowing through this circuit and you are with a group of other electrons. Suddenly you come to the ‘fork in the road’ and you and some of the other electrons are temporarily separated. A short while later you are back together with the other electrons. This type of circuit is called a(n) ____________ circuit.PLEASE HELP!!!

Answers

You knew that this question is ridiculously easy. So, just to
make it harder, you decided not to let us see the picture, so
that we could not "examine the circuit".

The description is talking about a parallel circuit. The other
kind is a series circuit, and that one has no forks in the road.

Answer:

parallel

Explanation:

In an electric circuit a ‘fork in the road’ appears in a parallel configuration. This kind of circuit is characterized by the different currents each 'road' take after the bifurcation, depending on the different resistance each one has. The voltage remains the same for every 'road'.
