Given:
The mass of the truck is m1 = 3162 kg
The speed of the truck is v1i = 12 m/s in East
The mass of the parked car is m2 = 510 kg
The speed of car is v2i = 0 m/s
The speed of car after collision is v2f = 24 m/s in East
To find the speed of the truck after collision.
Explanation:
The final velocity of the truck will be
Thus, the speed of the truck after collision is 8.129 m/s
Answer:
If the same volume of air is inhaled and exhaled, the air we breathe out normally weighs more than the air we breathe in.
Since the output from the body normally exceeds the input, breathing leads to weight loss.
Explanation:
If equal volumes of gas is inhaled and exhaled, the exhaled gas is heavier.
The inhaled gas contains Oxygen and majorly Nitrogen.
The exhaled gas contains CO₂, H₂O and a very large fraction of the unused inhaled air that goes into the lungs.
So, basically, the body exchanges O₂ with CO₂ and H₂O (and some other unwanted gases in the body) in a composition that CO₂, the heavier gas of the ones mentioned here, is prominent.
So, because the mass leaving the body is more than the mass entering, breathing leads to a loss of weight. This is one of the reasons why we need food for sustenance. Breathing alone will wear one out.
<h3><u>
Answer;</u></h3>
B) Not Balanced
B) Sodium
B) Not Equal
The equation is <em><u>not balanced</u></em> because the number of <em><u>sodium atoms</u></em> is <em><u>not equal</u></em> on both sides of the arrow.
<h3><u>Explanation;</u></h3>
- <em><u>According to the law of conservation of mass, the mass of reactants should always be the same as the mass of the products in a chemical equation.</u></em> Therefore, the number of atoms of each element in a chemical equation should always be the same on both sides of the equation, that is the side of reactants and side of products.
- Therefore,<u><em>any chemical equation requires balancing to ensure that the number of atoms of each element is equal in both sides of the equation</em></u>. Balancing is a try and error process that ensures that the law of conservation of mass holds.
- Thus, the balanced chemical equation is;
2Na + Cl2 → 2NaCl

Your answer: shared electrons
There would usually be two forces that would make an atom stick together. It would be the positive, and negative of a electric charge. All this coming together would be the electromagnetic force. This is liked we talked about, both positive and negative charges attracted. And that would be the strong force. Which then gives our answer to be electrons.
