Water, with a density of rho = 1125 kg/m 3 rho=1125 kg/m3 , flows in a horizontal pipe. In one segment of the pipe, the flow speed is v 1 = 6.53 m/s v1=6.53 m/s . In a second segment, the flow speed is v 2 = 1.17 m/s v2=1.17 m/s . What is the difference between the pressure in the second segment ( P 2 P2 ) and the pressure in the first segment ( P 1 P1 )?

Answer:

The difference between the pressure in the second segment (P2) and the pressure in the first segment (P1) is 23262.75N/m^2

Explanation:

Density (rho) of water = 1125kg/m^3

Flow speed (v1) in the first segment = 6.53m/s

From the equations of motion

v^2 = u^2 + 2gh (v = 6.53m/s, u = 0m/s, g = 9.8m/s^2)

6.53^2 = 2×9.8×h

h = 42.6409/19.6 = 2.18m

P1 = h×rho×g = 2.18×1125×9.8 = 24034.5N/m^2

Flow speed (v2) in the second segment = 1.17m/s

v^2 = 2gh

h = v^2/2gh = 1.17^2/2×9.8 = 1.3689/19.6 = 0.070m

P2 = h×rho×g = 0.070×1125×9.8 = 771.75N/m^2

P2 - P1 = 24034.5N/m^2 - 771.75N/m^2 = 23262.75N/m^2

An arsenic surface emits electrons after shining with a light source of the frequency of 5.32×1023 Hz. Calculate the maximum kinetic energy of the ejected electron if the work function of arsenic is 7.67×10.

Answer:

The maximum kinetic energy of the ejected electron=

Explanation:

We are given that

Frequency of light source= Hz

Work function of arsenic= eV

We have to find the maximum kinetic energy of ejected electron.

We know that the maximum kinetic energy of ejected electron

Where h=Plank's constant=

=Frequency of light source

=Work function

Substitute the values in the given formula

Then, the maximum kinetic energy of ejected electron

Because 1 e V=

J

Hence, the maximum kinetic energy of the ejected electron=

How does end A of the rod react when the charged ball approaches it after a great many previous contacts with end A? Assume that the phrase "a great many" means that the total charge on the rod dominates any charge movement induced by the near presence of the charged ball.

Answer: IT IS STRONGLY REPELLED

Explanation: The laws of guiding magnetic attraction or repulsion of Magnetic materials,states that when like poles are brought together they repel each other, but when unlike poles are brought together they are attracted.

The rod will be strongly repelled because the forces on the rod is greater and has the same Polarity as the charged ball.
