While taking a shower, you notice that the shower head is made up of 36 small round openings, each with a radius of 1.4 mm. you also determine that it takes 7.0 s for the shower to completely fill a 1- liter container you hold in the water stream. the water in your house is pumped by a pump in the basement, 6.2 m below the level of the shower head. the pump maintains an absolute pressure of 1.6 atmospheres. neglect viscosity. use g = 9.8 m/s/s, and 1 atmosphere = 101,300 pa.

[1 point] (a) what is the total area of the openings in the shower head?

[2 points] (b) at what speed is the water emerging from the holes?

cconnected to the pump (assume it has a constant cross-sectional area)?

[2 points] (c) at what speed is the water flowing through the pipe

[2 points] (d) what is the radius of the pipe?

[1 point] (e) if you covered up six of the holes in the shower head with your thumb, with what speed would you expect the water to emerge from the remaining holes?

answer; i believe the correct answer is (40,000 j) good luck

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:

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
