Answer:
P_(pump) = 98,000 Pa
Explanation:
We are given;
h2 = 30m
h1 = 20m
Density; ρ = 1000 kg/m³
First of all, we know that the sum of the pressures in the tank and the pump is equal to that of the Nozzle,
Thus, it can be expressed as;
P_(tank)+ P_(pump) = P_(nozzle)
Now, the pressure would be given by;
P = ρgh
So,
ρgh_1 + P_(pump) = ρgh_2
Thus,
P_(pump) = ρg(h_2 - h_1)
Plugging in the relevant values to obtain;
P_(pump) = 1000•9.8(30 - 20)
P_(pump) = 98,000 Pa

Answer:
A frame of reference is the location from which motion is perceived and measured. For all observers, the speed of light remains constant.
Explanation:
Answer:
0.006 m
Explanation:
d = separation between the slits = 0.150 mm = 0.150 x 10⁻³ m
λ = wavelength of the light = 643 nm = 643 x 10⁻⁹ m
D = distance of the screen where interference pattern is observed = 140 cm = 1.40 m
δ = Path difference
Path difference is given as
δ = Dλ/d
δ = (1.40) (643 x 10⁻⁹)/(0.150 x 10⁻³)
δ = 0.006 m
