An artist designed a badge for a school club. figure abcd on the coordinate grid below shows the shape of the badge.

the badge is enlarged and plotted on the coordinate grid as figure jklm with point j located at (-4, -7) and point m located at (-2, -3).

which of these could be the possible coordinates for vertex l?

(-1, -7)
(3, -7)
(0, -3)
(2, -3)

answer: i don't know the answer good luck

explanation:

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.

explanation:

magnets not strong enough
