Here is how I would I explain it. Water is channeled through tunnels in the dam. The energy of water flowing through the dam’s tunnels cause turbines to turn. The turbines make generators move. Generators are machines that produce electricity. Engineers control the amount of water let through the dam. The process used to control this flow of water is called the intake system.
Hope this helps can’t do the diagram part.
Answer:
water heights of the tube are 0.851 m , 0.553 m, 0.255 m
Explanation:
given data
frequency = 580 Hz
temperature = 20°C
tube = 1 m
to find out
water heights of the tube
solution
we will apply here formula for length that is
length L = v ( 2n -1 ) / 4f
here v is velocity o sound that is 343.2 m/s
so for n = 1
L = 343.2 ( 2(1) -1 ) / 4(580) = 0.147931 m
for n = 2
L = 343.2 ( 2(2) -1 ) / 4(580) = 0.443793 m
for n = 3
L = 343.2 ( 2(3) -1 ) / 4(580) = 0.739655 m
for n = 4
L = 343.2 ( 2(4) -1 ) / 4(580) = 1.035517 m is greater than 1
and so here height is measured less than 1 m
so water heights of the tube are 1 m - 0.147931 m , 1 m - 0.443793 m, 1 m - 0.739655 m
so water heights of the tube are 0.851 m , 0.553 m, 0.255 m
Ultrasound is vibrations, just like sound is vibrations. Ultrasound travels though the body just like sound would and when it hits something, it bounces back, where it is picked up by a receiver. which then makes an image out of it.
X-rays are electromagnetic waves, like visible light. Other examples of electromagnetic waves are infrared, and ultraviolet. But people cant see infrared nor ultraviolet, even though they are just like visible light. The difference between visible light and all these other kinds of light are just like the difference between red and blue. They are both light but different colors, ultraviolet and infrared are colors we cannot see, and in fact, we can see only a tiny portion of the colors out there. X-rays are just like all these kinds of light and we cant see it but it is able to go through most of the body, bot not bone. Doctors use x-rays to see bones and things like that in the body because x-rays won't pass through bone, but they will go through muscle and skin. So when a doctor takes an x-ray, its just like making a silhouette, but with colors we cant see. Of course, the x-rays make the photo paper change color and that's how we are able to see the image but the principle is the same.
The kinetic energy, potential energy and total mechanical energy possessed by the skydriver are 1.5 × 10⁵ Joule, 6.7 × 10⁵ Joule and 8.2 × 10⁵ Joule respectively.
To find the answer, we need to know about the expression of kinetic energy and potential energy.
<h3>
What are the expressions of kinetic energy and potential energy?</h3>
- Mathematically, kinetic energy= 1/2 × mass × velocity²
- Gravitational potential energy near the earth surface= mass × g × height on the earth surface
<h3>What's the kinetic energy, potential energy and total mechanical energy of the 78kg skydriver at 870 m on earth surface with 62 m/s velocity?</h3>
- Kinetic energy= 1/2 × 78 × 62² = 1.5 × 10⁵ Joule
- Potential energy= 78×9.8×870= 6.7× 10⁵ Joule
<h3>What's the total mechanical energy?</h3>
- Mechanical energy= kinetic energy+ potential energy
- 1.5 × 10⁵ Joule + 6.7× 10⁵ Joule = 8.2× 10⁵ Joule
Thus, we can conclude that the kinetic energy, potential energy and total mechanical energy possessed by the skydriver are 1.5 × 10⁵ Joule, 6.7 × 10⁵ Joule and 8.2 × 10⁵ Joule respectively.
