The water pressure to an apartment is increased by the water company. the water enters the apartment through an entrance valve at the front of the apartment. where will the increase in the static water pressure be greatest when no water is flowing in the system? a) at a faucet close to the entrance valveb) at a faucet far from the entrance valvec) it will be the same at all faucets. d) there will be no increase in the pressure at the faucets.

C) True. The pressure is the same in all faucets

Explanation:

This exercise should be analyzed in the view of Pascal's law that states that a change in pressure in a liquid is transmitted to all points of the liquid and the walls that contain it, assuming that the liquid has no viscosity.

In this case the company increased the pressure at the inlet, this increase should transmit with the same value to all water intakes, the viscosity of the water is small.

Let's check the answers

A) False. The pressure is the same at all points

B) False.

C) True. The pressure is the same in all faucets

D) false. Pressure changes

at right angles to each other

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
