Agolf course sprinkler system discharges water from a horizontal pipe at the rate of 7200 cm^3/s. at one point in the pipe, where the radius is 4.00 cm, the water's absolute pressure is 2.40×10^5 pa. at a second point in the pipe, the water passes through a constriction where the radius is 2.00 cm. what is the water's absolute pressure as it flows through this constriction?

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

the answer is b, have negligible mass

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

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
