Answer: The correct answer is "faster speeds".

Explanation:

Red shift: Light changes as the object in space (such as galaxy or star) moves away from us then the light is shifted to red end. In this case, the light is shifted to longer wavelength or the light shifted to a shorter frequency.

Faster the galaxy is moving away from the observer then there will be greater red shift. Slower the galaxy is moving away from the observer then there will be lesser red shift.

Therefore, Greater red shifts in the spectra of galaxies indicate faster speeds.

The main water line enters a house on the first floor. The line has a gauge pressure of 2.10 x 105 Pa. (a) A faucet on the secon

To answer this question is necessary to apply the concepts related to Bernoulli's equation. The Bernoulli-related concept describes the behavior of a liquid moving along a streamline. Pressure can be defined as the proportional ratio between height, density and gravity:

$P = h\rho g$

Where,

h = Height

$\rho$ = Density

g = Gravity

Our values are

$\rho = 1000kg/m^3 \rightarow$ density of water at normal conditions

h = 7.3m

$g = 9.8m/s^2$

PART A) Replacing these values to find the total pressure difference we have to

$P_1 = h_1 \rho g$

$P_1 = (7.3)(1000)(9.8)$

$P_1 = 71540Pa$

In this way the pressure change would be subject to

$\Delta = P_2-P_1$

$\Delta = 2.1*10^5Pa- 0.7154*10^5Pa$

$\Delta = 138460Pa$

$\Delta = 0.135Mpa$

PART B) Considering the pressure gauge of the group as the ideal so that at a height H the water cannot flow even if it is open we have to,

$P_2 = H\rho g$

$2.1*10^5 = H (1000)(9.8)$

$H = 21.42m$

Therefore the high which could a faucet be before no water would flow from it is 21.42m

A deer walks 17.0 m south and then 12.0 m north. Find both the magnitude of its displacement and the distance traveled.

Zepler [3.9K]

Answer:

Explanation:

Displacement involves direction and distance. In this case, the deer has walked a distance of 17 + 12 = 29m but because of the South-then-North direction, the net displacement is only 17-12 = 5m.

So the answer is A) 5.0 m, 29.0 m
