Answer:
the seed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance divided by Time
So, here speed be 515m
And, the time is 1.50 second
So, the speed of the sound is
= 515m divided by 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s
True statements that reflect why infants experience more fluid and electrolyte changes are that dehydration can upset the balance of electrolytes in an infant or child and the newborn is at risk of excessive water loss and hypernatremia as the result of high evaporative water loss through the skin.
As infants are not used to the environment around , they are more sensible towards problems such as Dehydration because of fast metabolism.
Dehydration can upset the balance of electrolytes in an infant or child. Children are especially vulnerable to dehydration due to their small size and fast metabolism, which causes them to replace water and electrolytes at a faster rate than adults.
Infants are particularly prone to the effects of dehydration because of their greater baseline fluid requirements (due to a higher metabolic rate), higher evaporative losses (due to a higher ratio of surface area to volume), and inability to communicate thirst or seek fluid.
The newborn is at risk of excessive water loss and hypernatremia as the result of high evaporative water loss through the skin, insensible water loss (IWL), as well as decreased capacity to concentrate the urine.

A loess is...
<em>A clastic, silt-sized sediment that is formed by the accumulation of wind-blown dust. 10% of the earth's area is covered by loess or similar deposits. </em>

Answer:
Part a)
Rate of charge flow is known as electric current
Part b)
Average current flow is
![i = 4\times 10^{-7} A](https://tex.z-dn.net/?f=i%20%3D%204%5Ctimes%2010%5E%7B-7%7D%20A)
Part c)
As we know that current density is current per unit area
![j = 1.27 \times 10^{-3} A/m^2](https://tex.z-dn.net/?f=j%20%3D%201.27%20%5Ctimes%2010%5E%7B-3%7D%20A%2Fm%5E2)
Explanation:
As we know that angular frequency of rotation is
![\omega = 100\pi rad/s](https://tex.z-dn.net/?f=%5Comega%20%3D%20100%5Cpi%20rad%2Fs)
now by basic definition of electric current
Part a)
Rate of charge flow is known as electric current
![i = \frac{dq}{dt}](https://tex.z-dn.net/?f=i%20%3D%20%5Cfrac%7Bdq%7D%7Bdt%7D)
so here we have
![i = \frac{Q}{T}](https://tex.z-dn.net/?f=i%20%3D%20%5Cfrac%7BQ%7D%7BT%7D)
![i = Qf](https://tex.z-dn.net/?f=i%20%3D%20Qf)
Part b)
here we know that
![\omega = 2\pi f](https://tex.z-dn.net/?f=%5Comega%20%3D%202%5Cpi%20f)
![100\pi = 2\pi f](https://tex.z-dn.net/?f=100%5Cpi%20%3D%202%5Cpi%20f)
![f = 50 Hz](https://tex.z-dn.net/?f=f%20%3D%2050%20Hz)
now we have
![i = (8\times 10^{-9})(50)](https://tex.z-dn.net/?f=i%20%3D%20%288%5Ctimes%2010%5E%7B-9%7D%29%2850%29)
![i = 4\times 10^{-7} A](https://tex.z-dn.net/?f=i%20%3D%204%5Ctimes%2010%5E%7B-7%7D%20A)
Part c)
As we know that current density is current per unit area
So we have
![j = \frac{i}{A}](https://tex.z-dn.net/?f=j%20%3D%20%5Cfrac%7Bi%7D%7BA%7D)
![j = \frac{4\times 10^{-7}}{\pi(10\times 10^{-3})^2}](https://tex.z-dn.net/?f=j%20%3D%20%5Cfrac%7B4%5Ctimes%2010%5E%7B-7%7D%7D%7B%5Cpi%2810%5Ctimes%2010%5E%7B-3%7D%29%5E2%7D)
![j = 1.27 \times 10^{-3} A/m^2](https://tex.z-dn.net/?f=j%20%3D%201.27%20%5Ctimes%2010%5E%7B-3%7D%20A%2Fm%5E2)
Answer:
Mono-chromatic, Poly-chromatic. When a wave moves from one medium into another at an angle other than 90 degrees the wave will change direction and continue to follow a new straight-line path
