According to Distributed practice theory, which of these study patterns is the most effective? Question 18 options: 1 hour of studying just before the test four 1 hour study sessions the day before the test eight 1 hour study sessions the week leading up to the test 8 hours of studying the night before the test

atomic = no of protons.

mass number-atomic number = neutron number

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:

i think it would be 5

the maxium height is 34m/s
