Answer:
1) p v q: A student is in the Math Club or is in the debate Club. 2) p v q is not true for all students. (Check the table below)
Explanation:
In Logic, we have symbols for those propositions. This is a disjunction.
1) The verbal translation for this:
Since
p: A student is in the Math Club
q: A student is in the debate club
p v q: A student is in the Math Club or is in the debate Club.
2) By doing the Table Truth, we can see when this is true. The only possible way a disjunction is false is when both single statements are false.
Check below.
Answer:
1. The mesosphere is very important for earth’s protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth’s surface. The mesosphere is the coldest atmospheric layer surrounding the earth. It becomes cold enough to freeze water vapour in its atmosphere into ice clouds.
2. the layer of the earth's atmosphere that contains a high concentration of ions and free electrons and is able to reflect radio waves. It lies above the mesosphere and extends from about 50 to 600 miles (80 to 1,000 km) above the earth's surface.
