An object in motion eventually stops because of friction.
<h3>What is Newton’s first law of motion?</h3>
Newton's first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or continue its moving in a straight line at constant speed unless force is applied on it.
So we can conclude that An object in motion eventually stops is the correct answer.

Answer:
10,200 Cal. per day
Explanation:
The mouse consumes 3.0 Cal each day, and has a mass of 20 grams. We can use this data to obtain a ratio of energy consumption per mass
.
For the human, we need to convert the 68 kilograms to grams. We can do this with a conversion factor. We know that:
,
Now, we can divide by 1 kg on each side
,
.
Using this conversion factor, we can obtain the mass of the human in grams, instead of kilograms. First, lets take:

We can multiply this mass for the conversion factor, we are allowed to do this, cause the conversion factor equals 1, and its adimensional


Now that we know the mass of the human on grams, we can multiply for our ratio of energy consumption

So, we would need 10,200 Cal per day.
Equivalent resistance is also known as the overall resistance.
For resistors in a series circuit, the total resistance is computed using the formula:

In other words, you just add up the resistance of each resistor in the series circuit. In your case you only have two resistors. You have 2Ω and 4Ω. So all you need to do is add that up.


The total resistance of the series circuit is 6Ω
In a parallel circuit you get the total resistance using the formula:

First you get the sum of all fractions and at the end take the reciprocal of the resulting fraction and divide. So let us take your problem into consideration where you have two resistors that have a resistance of 2Ω and 4Ω.




Get the reciprocal of the resulting fraction 3/4 and then divide. The reciprocal of 3/4 is 4/3.
4/3 = 1. 33Ω
So if you compare the equivalent resistance of the two circuits, the series circuit has a higher equivalent resistance.
