The escape velocity formula has nothing to do with what is trying to escape. That means that the mass of the lunar module is not needed.
Formula
v = sqrt( (2 * G * M) / R)
Givens
v = ??
G = 6.67 * 10^-11 This is the gravitational constant.
M = 7.34 * 10^22 kg
R = 1.74 * 10^6 m
Solution
v = sqrt( 2 * 6.67 * 10^- 11 * 7.34*10^22/1.74*10^6)
v = sqrt(9.79156* 10^12 / 1.74 * 10^6)
v = sqrt(5.627 * 10^6)
v = 2372 m/s
Answer:
-411 kj
Explanation:
We solve by using this formula
∆U = ∆Q + ∆W
This formula is the first law of thermodynamics
Change in internal energy U = +241
Heat gained by system Q = 652
Putting the value into the equation
+241 = 652 + W
Workdone = 241 - 652
Workdone = -411 kj
Since work done is negative it means that work was done by the system
Answer: The SI unit for measuring distance is meter
Explanation:
Answer:
A combustion reaction is a reaction that involves a substance and oxygen reacts at high temperature and produces light energy and thermal energy and generate light and heat.
If a flame is in a sealed container it will go out due to the absence of oxygen to perform a combustion reaction that requires oxygen to produce heat and light. A flame is the result of a combustion reaction which also requires the oxygen to keep on burning.
