After you chew and swallow, food enters your digestive system where it can be broken down.

Answer:

A

Explanation:

Technically, your mouth is part of the digestive system though so I am not sure how accurate this question is.

The flow rate over Niagara falls is 84,760 cfs (cubic feet per second), and the drop from top to bottom is 167 feet. If this flo

jekas [21]

To develop this problem we will calculate the volume from the given flow (volume per unit of time). This process will be accompanied by transforming the units given in the International system.

Through the density-volume-mass ratio, we will calculate the mass. Finally we will proceed to calculate the total power generated.

1 feet = 0.3048 m

$\dot{V} = 84760ft^3/s$

$\dot{V} = 84760ft^3/s (\frac{(0.3058m)^3}{(1ft)^3})$

$\dot{V} = 2400m^3/s \text{and the Volume each second is } V= 2400m^3$

Now the mass of water falling down each second would be

$\rho = \frac{m}{V} \rightarrow m = \rho V$

$m = (1000kg/m^3)(2400m^3)$

$m = 2.4*10^6kg$

Now Height in meters is

$h = 167 ft (\frac{(0.3058m)}{(1ft)})$

$h= 50.9 m$

The power produced is equivalent to the work done by gravity over a certain time. At this case that can be expressed as,

$P = \frac{W}{t}\\P = \frac{F*h}{t}\\P = \frac{mgh}{t}\\P = \frac{2.4*10^6*9.8*50.9}{1}\\P = 1.197*10^9 Watts$

The power of Niagara Falls then would be 1.197GW while the power generated by the Three Gorges Dam is 22,500 MW. This indicates that the Niagara Falls, if it were a dam that covered 100% of the fluid it carries, would exceed the production of the dam in China by thousands.

A particle is moving along the x-axis so that its position at any time t is greater than and equal to 0 is given by x(t)=2te^-t?

erastovalidia [21]

For speed you can differentiate the equation, for acceleration you can again differentiate the equation .
at t=0 the particle is slowing down , when you get equation for velocity put t=0 then only -1 is left

Water vapor in earth's atmosphere primarily absorbs which type of photon

Charra [1.4K]

Any object having a temperature greater than absolute zero gives off electromagnetic radiation. Water in the atmosphere primarily known as water vapor upon encountered by the heat released by the sun emits relatively long wavelengths of infrared photons. These infrared photons moved up to the more elevated level in the atmosphere since it is now highly reactive.
