1. What events cause the formation of elements more massive than iron in the periodic table?

SAT
1 answer:
Alexandra [31]3 years ago
7 0

Answer:

1: The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.

Explanation:

2: The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.

Triangle PQR has right angle Q. If sin R = 4/5<br> what is the value of tan P?
icang [17]

By applying Pythagorean' theorem, the value of tanP is equal to 3/4.

<h3>How to determine the value of tan P?</h3>

Since triangle PQR has right-angle Q and sinR = 4/5, we have:

sinR = Opp/hyp = 4/5

tanP = Opp/Adj = QR/4

Next, we would determine the length of QR by applying Pythagorean' theorem:

PR² = QR² + PQ²

5² = QR² + 4²

25 = QR² + 16

QR² = 25 - 18

QR = √9

QR = 3 units.

For the value of tanP, we have:

tanP = 3/4.

Mai is making personal pizzas. For 4 pizzas, she uses 10 ounces of cheese. Consider using a table to help answer the questions b
Step2247 [10]

Based on the amount of cheese used for the pizzas, the following are true:

  • a. Mai uses 2.5 ounces of cheese per pizza.
  • b. Mai will need 37.5 ounces for 15 pizzas.

<h3>Cheese used per Pizza. </h3>

This can be found as:

= Ounces of cheese used / Number of pizzas

= 10 / 4

= 2.5 ounces per pizza.

<h3 /><h3>Cheese needed for 15 pizzas. </h3>

= Number of pizzas x Cheese per pizza

= 15 x 2.5

= 37.5 ounces of cheese.

In conclusion, Mai needs 37.5 ounces of cheese to make 15 pizzas.
