Answer:

7.9 x 10^21 pound-force

Explanation:

The average distance between the Earth and sun is 150 trillion meters, or 1.5 x 10^11 meters. The mass of the sun is 1.99 x 10^30 kilograms, while the Earth weighs in at 6.0 x 10^24 kilograms. The gravitational constant is 6.67 x 10^-11 meter^3 / (kilogram - second^2). So the Earth and sun pull on each other with a force equal to 3.52 x 10^22 newtons. The newton is a unit of force equal to a kilogram-meter/second^2. One newton is equal to 0.22 of the rarely used English unit called pound-force, so 3.52 x 10^22 newtons is 7.9 x 10^21 pound-force.

a spring has a spring constant of 80N/m. How much energy is stored in the spring when it is compressed 0.2m past it's natural le

Alex73 [517]

Answer:

1.6 J (Joules)

Explanation:

Since the potential energy of a spring can be found from the equation PE = 1/2 * k * x^2, the PE is 1/2 * 80 *.2^2 = 1.6 J

A two-liter bottle is one-fourth full of water and three-quarters full of air. The air in the bottle has a gage pressure of 340

Fantom [35]

Answer:

The value is $P_G = 2.925 *10^{5} \ Pa$

Explanation:

From the question we are told that

The volume of the bottle is $v = 2 \ L = 2 * 10^{-3} \ m^3$

The gauge pressure of the air is $P_g = 340 \ kPa = 340 *10 ^{3} \ Pa$

Generally the volume of air before the bottle is turned upside down is

$V_a = \frac{3}{4} * V$

$V_a = \frac{3}{4} * 2 *10^{-3}$

$V_a = 0.0015 \ m^3 }$

Generally the volume air when the bottle is turned upside-down is

$V_u = \frac{5}{6} * 2 *10^{-3}$

$V_u = 0.00167 \ m^3$

From the the mathematical relation of adiabatic process we have that

$P_g * V_a^r = P_G * V_u^r$

Here r is a constant with a value r = 1.4

So

$340 *10 ^{3} * 0.0015^{1.4} = P_G * 0.00167^{1.4}$

$P_G = 2.925 *10^{5} \ Pa$
