The oil spill in the gulf of mexico has gained national attention due to the harmful
effects that it has had on the ecosystem. in your science class, you have learned
that some substances don't mix. instead, they layer based on their densities.
obtain evaluate, and communicate information about the physical property of
density and how it applies to drilling oil and disasters such as oil spills. reflect on
what you have learned about how things layer based on their densities. knowing
what happens when oil and water come in contact, write a letter to the president
of bp oil that 1. constructs an argument based on evidence for why we should or
shouldn't drill, and 2. propose ways in which an oil spill can be contained and/or
cleaned up
use this document to organize your information and type your letter

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:

would be false hope this out

prolly a beacuse the momentuem the car has increases while going down hill
