Answer:

The external forces such as wind, water and the vibration of the earth when an earthquake happens create internal forces within a structure. Internal forces such as shear, tension and compression can destroy the inner framework of a building or a bridge even though it is made of super strong steel and concrete.

One gallon of gasoline in an automobiles engine produces on average 9.50 kg of carbon dioxide, which is a greenhouse gas; that i

Musya8 [376]

The annual production of carbon dioxide is 124121.49×10^{6}[/tex] kg.

First we calculate the fuel consumed by each car in a year

Fuel consumed=6990/21.4=326.63 gallon

Now we calculate the amount of fuel consumed by 40 million cars in a year

Fuel consumed=326.63*40*10^6=13065.42 million gallon,

Now we can calculate the annual production of carbon dioxide in the USA

CO2 production rate=9.50*13065.42=124121.49*10^6 kg

Therefore the annual production of carbon dioxide in USA is 124121.49×10^{6}[/tex] kg

The distance between Pluto and the Sun is 39.1 times more than the distance between the Sun and Earth. Calculate the time taken

german

Answer:

Explanation:

Given

Distance between Pluto and sun is 39.1 times more than the distance between earth and sun

According to Kepler's Law

$T^2=kR^3$

where k=constant

T=time period

R=Radius of orbit

Suppose $R_1$ is the radius of orbit of earth and sun

so Distance between Pluto and sun is $R_2=39.1\cdot R_1$

$T_1$ and $T_2$ is the time period corresponding to $R_1$ and R_2[/tex]

$(T_1)^2=k(R_1)^3---1$

$(T_2)^2=k(R_2)^3---2$

divide 1 and 2

$(\frac{365}{T_2})^2=(\frac{R_1}{39.1})^3$

$T_2^2=365^2\times 39.1^3$

$T_2=89239.67\ Earth\ days$
