Answer:
D. By adding the vectors
Explanation:
Given
Represent the velocity of the river current as VR
Represent the velocity of the boat as VB
Required
How to calculate the velocity of boat relative to river current
From the question, we understand that both move in the same direction.
So, the relative velocity V is calculated as:
Notice that the both velocities are added together to get the relative velocities.
This is so because they both move in the same direction
<em>From the list of given options, only option D is correct.</em>
Formula:
Hydrogen Chloride = HCl (Chemical Compound)
Sodium = Na (Chemical Element)
Reactants:
A simple definition of a reactant can be the substances that go into a chemical reaction. By substances I mean any chemical.
Products:
A simple definition of a product can be the substances produced at the end of the reaction. Again by substances I mean any chemical.
Definition of the answer:
We know that Sodium is a Chemical Element and as decribed in the picture it was mixed by Hydrogen Chloride and we know that is a Chemical Compound. So in this case the Na CI can be the product that was produced at the last and it was the result after the chemical reaction was taken place. The reactant can be the Sodium. I chose that because Reactant is a substance/chemical that goes into a chemical reaction. So as seen in the picture it went into the beaker.
Hope this helps.
Answer:
material that current can pass through easily
Answer: Most adults consume and excrete about <u>1.5 to 3</u> quarts of water per day. Adults are advised to consume <u>1</u> to <u>1.5</u> mL of water from all sources for each calorie expended. A person who needs 2,400 calories per day will require <u>2400 to 3600</u> mL of water per day.
Explanation: To balance the water intake with the calories consumed every day, it is necessary to drink 1 to 1.5 mL of water for every calorie taken in, in order to cease the calorie from accumulating as fat. Generally, adults drink between 1.5 and 3 quarts of water and excrete proportionally every day.
This can be considered to be a healthy habit as long as the calorie intake does not exceed its proportionate limit. It is necessary to strike a balance between water intake and calorie intake so as to maintain a healthy metabolism.
To mean learning and education is a big contribution as to my future self. I have plans for my future, I want to help lives and save(be in the medical field). without proper education that won't make me a safely trained person. education will help me be who I want to be.
