An energy bar contains of 20grams of carbohydrates and 1gram
is equal to 17 KJ. If the energy bar was his only fuel the total energy
available is equal to (17,000 x 20) = 340,000j. Estimate KJ per hour is equal
to 1539KJ, it has Time equal to (340,000/1539,000) is equal to 0.2209 hour and
his Distance is equal to (5,000 x .2209) = 1.1045km.
<h2>Answer: Mercury</h2><h2 />
The Mariner 10 probe was launched by NASA on November 3rd, 1973, with the purpose of exploring the characteristics of two planets in the solar system that were closest to the Sun, Mercury and Venus.
In addition, it was launched to explore the atmosphere and surface of both planets and <u>prove that it was possible to use gravitational assistance</u> (also called <u>slingshot effect</u>, a special orbital maneuver in order to use the gravitational field energy of a planet or massive body to accelerate or slow the probe and change the direction of its trajectory) in long interplanetary trips to save fuel.
In this case, <u>Mariner 10 first arrived at Venus</u> and succeded in using its gravitational field to accelerate its trajectory towards Mercury.
By idea gas equation we can say

here P = pressure
V = volume
n = number of moles
R = Avagadro gas constant
T = temperature
So from above expression we can see that for constant number of moles we can say




So finally the pressure will be 279.1 kPa
