4. Bacteria move at 100 um/s. How long would it take one bacterium to move 1.0 m? 5. How far would a car move in 4.8 s if its velocity changed from 14.0 m/s to 16.0 m/s?
6. What is the displacement of a car accelerating from 15 m/s forward to 10 m/s forward in 8.0 s?
7. Apollo 10's re-entry speed was 39 897 km/h. How many seconds would it take the spacecraft to stop in a
distance of 3.0 x 106 m.

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:

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
