1.What types of geological events or changes occur at divergent plate boundaries?
Volcanoes and minor earthquakes occur at divergent plate boundaries.

2. What types of geological events or changes occur at convergent plate boundaries? Volcanoes, earthquakes and fold mountains occur at convergent plate boundaries.

3. What types of geological events or changes occur at transform plate boundaries? Earthquakes and fold mountains occur at transform plate boundaries.

4. Explain how these geological processes and interactions have changed Earth's surface through the years. Magma from volcanoes is filled with nutrients that makes land fertile. Some earthquakes make the ground shake so violently that it destroys entire landscapes and environments. Earthquakes can also cause landslides and tsunamis, which destroy whole villages, change geology and ruin natural habitats of many living creatures. W<span>hen an earthquake happens in the middle of the ocean, it can create waves that are so large that they destroy coastlines, cities, and forests hundreds of miles away.</span>

Una tubería con secciones circulares se emplea para el traslado de agua entre el tanque central y un tanque auxiliar. El tanque
charle [14.2K]

A) 20 L/s

B) 2.55 m/s

C) 10.20 m/s

D) 400.8 kPa

Explanation:

a)

In this problem, we know that the volume of the tank:

V=72 m^3  

is filled in a time of

t = 1 h

We also know that the volume flow rate of water in the pipe is constant in every point of the pipe, so it can be calculated directly from the two data above.

The volume of the tank, in liter, is

V=72 m^3 = 72,000 L

While the time, in seconds, is

t=1 h = 3600 s

Therefore, the volume flow rate in Liters per second is:

Q=\frac{V}{t}=\frac{72,000}{3600}=20 L/s

b)

The volume flow rate of water through the pipe can be also written as

Q=Av

where

A is the cross-sectional area of the pipe

v is the speed of the water

In section B, we have:

r = 0.050 m is the radius of section B

so, the cross-sectional area of section B is:

A=\pi r^2 = \pi (0.050)^2=0.00785 m^2

The volume flow rate in SI units is

Q=\frac{V}{t}=\frac{72.0m^3}{3600 s}=0.02 m^3/s

Therefore, the speed of the water in section B is:

v=\frac{Q}{A}=\frac{0.02}{0.00785}=2.55 m/s

c)

As in part B), we know that the volume flow rate must remain constant through the entire pipe.

So, the volume flow rate in section A of the pipe is still

Q=0.02 m^3/s

The radius of the pipe in section A is

r=0.025 m

Therefore, the cross-sectional area in section A of the pipe is

A=\pi r^2 = \pi (0.025)^2=0.00196 m^2

So, since we have

Q=Av

we can find the speed of water in section A:

v=\frac{Q}{A}=\frac{0.02}{0.00196}=10.20 m/s

d)

Here we want to find the gauge pressure in section B.

We know that:

p_A = 2.0 atm = 105,000 Pa is the pressure in section A

h_A=15.0m is the altitude of section A

v_A=10.20 m/s is the speed of water in section A

v_B=2.55 m/s is the speed of water in section B

We can write Bernoulli's equation:

p_A + \rho g h_A + \frac{1}{2}\rho v_A^2 = p_B + \frac{1}{2}\rho v_B^2

where

\rho=1000 kg/m^3 is the water density

p_B is the pressure in section B

And solving for pB, we find:

p_B = p_A + \rho g h_A + \frac{1}{2}\rho (v_A^2-v_B^2)=\\=205,000+(1000)(9.8)(15.0)+\frac{1}{2}(1000)(10.20^2-2.55^2)=400,769 Pa

Which is

p_B = 400.8 kPa
