Answer:
There are many infectious diseases for which we don't have an effective treatment. In these cases, the scientific community is working to understand the molecular mechanisms used by these pathogens to attack human cells. From a medical perspective, it is imperative to use treatments to improve the patient's life quality.
We are asked to convert from units of kilometer per second to units of miles per year. To do this, we need a conversion factor which would relate the different units involved. We either multiply or divide this certain value to the original measurement depending on what is asked. From literature, we will find that 1 mile is equal to 1609 meters and 1000 m is equal to 1 kilometer. Also, we will find that 3600 s is equal to 1 hr, 24 hr is equal to 1 day and 365 days is equal to 1 year. We do the conversion as follows:
3.8 km / s ( 1000 m / 1 km ) ( 1 mile / 1609 meters ) ( 3600 s / 1 hr ) ( 24 hr / 1 day ) ( 365 days / 1 year ) = 74479055.3 miles per year
Solar panels transform the energy from the light of the Sun and turns it into electricity.
Answer: 7.88375g
Explanation:
Here is the dimensional analysis table
7g O2 | 1 mol O2 | 2 mol H2O | 18.02 g H2O
| 32 g O2 | 1 mol O2 | 1 mol H2O
You use grams to convert to moles of O2, then use that to find grams of H20
Answer:
Copper Wire
Explanation:
Copper is a pure substance but they used it to make a man-made material. Therefore, it's not pure anymore.
