Read the sentence. one ancient misconception was that the earth was flat. if conceive means “to understand,” what does misconception mean? a. an ability to think for oneself; confident b. an act of falsely believing; error c. a system of induction and deduction; logical d. a process of completing a task correctly; accurate

The correct answer is B. An act of falsely believing

Explanation:

In language, the meaning of an unknown word can be determined by using context clues, in which the words that surround the unknown word are used to determine the type of word and possible meaning of it or by using the prefixes or suffixes that are part of the word to infer the meaning of the unknown word. In this case in the sentence " One ancient misconception was that the Earth was flat" the unknown word or word to be studied is "misconception". Considering this word is used to describe the belief that Earth was flat and this is a false belief, it can be guessed through the context clues this word means a false belief or the act of believing something false. Similarly, if the prefix "miss" which means "mistaken" or "incorrect" is considered along with the word "conception" that means "to understand" it can be concluded a misconception is an incorrect or mistaken belief. Therefore, the word misconception means "an act of falsely believing".

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.
