Explanation:

1. This passage is describing Sandy as a great singer and why she is a great singer. She sings in a church choir and she sings solo every week. Everyone thinks that she is a great singer and that she was the voice of an angel. They are describing her as someone who is successful and they are believing that she will be famous one day.

C) is the correct answer and other answers are not correct because they are considered as details that are leading her to the reputation of a great singer.

2. This passage is telling the readers that Tommy forgot to do an important thing which is closing the gate because of his dog. It is the main idea of the passage because in it we can see that his mother told him a hundred times to close it but he forgot. The central idea of the text is that he forgot to close the gate and his dog escaped.

3. The main idea of this paragraph is that Joy's mother forgot to pick her up and because of that Joy sat on the beach at the baseball field waiting for her mother. Her mother is sorry that she forgot to pick her up and she told her that next time she will make her a note so she does not forget.

4. The main idea of this paragraph is that the person had eaten a huge sundae in an Ice Cream shop and because of that he was not able to eat his favorite meal that his mother had cooked. He tried but he was already full and that is why he could not do it. Other answers are incorrect because they are not mentioned in the passage.

your answer is c) experiments with water vapor showed that elements combine in specific proportions.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
