Answer:

See the answer below

Explanation:

Natural gas from different countries has a different percentage of hydrocarbons <u>because they are formed from different biomass of organisms</u>.

<em>Natural gas is formed from decomposed organic matter that has been deposited millions of years ago. Layers of decomposing plants and animal matters buried deep in the ground experience intense heat and pressure and are eventually transformed after millions of years. </em>

Different countries have different diversity of organisms. Hence, the organic matter that eventually transforms into natural gas for each country also differ. The implication is that the natural gas that would be formed in each country would be different. This is why natural gas from different countries may have different percentages of hydrocarbons.

A certain unfiltered full-wave rectifier with 120 V, 60 Hz input produces an output with a peak of 15 V. When a capacitor-input

KATRIN_1 [288]

Answer:

The peak-to-peak ripple voltage = 2V

Explanation:

120V and 60 Hz is the input of an unfiltered full-wave rectifier

Peak value of output voltage = 15V

load connected = 1.0kV

dc output voltage = 14V

dc value of the output voltage of capacitor-input filter

where

V(dc value of output voltage) represent V₀

V(peak value of output voltage) represent V₁

V₀ = 1 - ( $\frac{1}{2fRC}$ )V₁

make C the subject of formula

V₀/V₁ = 1 - (1 / 2fRC)

1 / 2fRC = 1 - (v₀/V₁)

C = 2fR ((1 - (v₀/V₁))⁻¹

Substitute for,

f = 240Hz , R = 1.0Ω, V₀ = 14V , V₁ = 15V

C = 2 * 240 * 1 (( 1 - (14/15))⁻¹

C = 62.2μf

The peak-to-peak ripple voltage

= (1 / fRC)V₁

= 1 / ( (120 * 1 * 62.2) )15V

= 2V

The peak-to-peak ripple voltage = 2V

An open rectangular tank 1 m wide and 2 m long contains gasoline to a depth of 1 m. If the height of the tank sides is 1.5 m, wh

lara [203]

Answer:

$a_y = 4.9\ m/s^2$

Explanation:

Given,

Width of rectangular tank, b = 1 m

Length of the tank, l = 2 m

height of the tank, d = 1.5 m

Depth of gasoline on the tank, h = 1 m

$\dfrac{dz}{dy}=-\dfrac{1.5-1}{1}$

$\dfrac{dz}{dy}=-0.5$

The differential form with the acceleration

$\dfrac{dz}{dy}=\dfrac{-a_y}{a_z + g}$

$-0.5=-\dfrac{a_y}{a_z + g}$

acceleration in z-direction = 0 m/s²

g = 9.8 m/s²

a_y is the horizontal acceleration of the gasoline.

$0.5=\dfrac{a_y}{0 + 9.8}$

$a_y = 9.8\times 0.5$

$a_y = 4.9\ m/s^2$

Hence, Horizontal acceleration of the gasoline before gasoline would spill is equal to 4.9 m/s²

If the radius of a blood vessel drops to 84.0% of its original radius because of the buildup of plaque, and the body responds by

erma4kov [3.2K]

To develop this problem it is necessary to apply the equations concerning Bernoulli's law of conservation of flow.

From Bernoulli it is possible to express the change in pressure as

$\Delta P = \frac{1}{2}\rho (v_1^2-v_2^2)+ \rho g (h_1h_2)$

Where,

$v_i =$ Velocity

$\rho =$ Density

g = Gravitational acceleration

h = Height

From the given values the change of flow is given as

$R = r^4P$

Therefore between the two states we have to

$\frac{R_2}{R_1} = \frac{r_2^4 P_2}{r_1^4 P_1} *100\%$

$\frac{R_2}{R_1} = \frac{84^4 (110)}{100^4*(100)} *100\%$

$\frac{R_2}{R_1} = 54.77\%$

The flow rate will have changed to 54.77 % of its original value.
