Water (constant density) is to be pumped up a hill (gravity = (0,0,−g)) through a pipe which tapers from an area a1 at the low point to the smaller area a2 at a point a vertical distance l higher. what is the pressure p1 at the bottom, needed to pump at a volume rate q if the pressure at the top is the atmospheric value p0? (express in terms of the given quantities. assuming inviscid steady flow, use bernoulli’s theorem with gravity and conservation of mass. assume that the flow velocity is uniform across the tube in computing fluid flux and pressure.)

answer: the answer is a

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
