Which of the following is an example of inductive reasoning?

a. it was cool on the first day of summer, so the entire summer will be cool.
b. i heard on the radio that the first day of summer will be cool, so it will be cool today
c. it has been cool every day this summer so far, so tomorrow will likely be cool too.
d. june is the coolest summer month where i live, so it will probably be cool this june.

answer:

the correct answer is actually a

explanation: an example of inductive logic is, "the coin i pulled from the bag is a penny. therefore, all the coins in the bag are pennies." even if all of the premises are true in a statement, inductive reasoning allows for the conclusion to be false. here's an example: "harold is a grandfather is bald. therefore, all grandfathers are bald."

the objective should be switched

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.
