1. analyze the number line above to describe the motion of the object. be sure to include starting position, intermediate position, ending position, distance traveled, and displacement in your answer.

2. an object travels a distance of 6 meters in 2 seconds if average speed is found using the equation “ distance traveled/elapsed time” what is the average speed of the object? be sure to include units in your answer.

3. an object has a displacement of +12 meters in six seconds. if average velocity is found using the equation “ change of position/elapsed time” what is the average velocity of the object? be sure to include the correct sign and units in your answer.

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.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
