\huge\mathsf{\red{\underline{\underline{Answer}}}}

{\green{\dashrightarrow}}When an opaque obstacle is placed between a source of light and a screen, a shadow of the obstacle is formed on the screen. The kind of shadow depends on the size of the source of light. In other words, the earth casts its shadow on the moon. The solar eclipse occurs when the moon comes between the sun and the earth.

Lunar eclipses occur whenever the full moon passes into the shadow of the earth. Solar eclipses occur when the new moon slips in front of the sun and blocks it from view. The moon's shadow then falls upon the earth.

The acceleration of gravity is 9.8m/s2. How fast will an object be moving if it falls for three seconds?
Mice21 [21]

Answer:

Acceleration

\frac{distace}{time}

When we cross multiply, distance will be equal to acceleration multiply by time

Distance = acceleration x time

Distance = 9.8 x 3

= 29.4 m/s

A gas bottle contains 0.650 mol of gas at 730 mm Hg pressure. If the final pressure is 1.15 atm, how many moles of gas were adde
AlekseyPX

Answer:

0.779 mol

Explanation:

Since the gas is in a bottle, the volume of the gas is constant. Assuming the temperature remains constant as well, then the gas pressure is proportional to the number of moles:

p \propto n

so we can write

\frac{p_1}{n_1}=\frac{p_2}{n_2}

where

p1 = 730 mm Hg = 0.96 atm is the initial pressure

n1 = 0.650 mol is the initial number of moles

p2 = 1.15 atm is the final pressure

n2 is the final number of moles

Solving for n2,

n_2 = n_1 \frac{p_2}{p_1}=(0.650 mol)\frac{1.15 atm}{0.96 atm}=0.779 mol

Problem 2: Estimate the electric power requirement, in kW, of a 1,400 ft2floor area (three bedroomshome) with three occupants. U
stira [4]

Answer:

a) 3170 kw

b) 377 km^2

Explanation:

Estimate of electric power

a) Given :

Average power consumption for a family of 3 = 108.4 * 106 BTU per year  =  0.0317 kw = 31.7 watts

<u>The power requirement for a city of 300000 people </u>

= 31.7 watts * 100000 = 3170000 watts = 3170 kw

b) Given :

Average solar panel insulation = 8.4 W /m^2

<u>Estimate the area of silicon solar cells required to satisfy community power requirement</u>

= (1 * 3170) * (1000/8.4 )

= 377.380 * 10^3 m2 = 377 km^2
