The answer is: Absolute brightness is the actual amount of light produced by the star, whereas apparent brightness changes with distance from the observer. Hope this helps, and have a great day
Answer:
The answer to your question is weight = 1667 N
Explanation:
Data
density = 2.40 x 10³ kg/m³
volume = 0.0708 m³
Force = 66.7 N
weight of the block = ?
- Formula
density = mass / volume
- Solve for mass
mass = density x volume
-Substitution
mass = (2.40 x 10³)(0.0708)
-Result
mass = 169.92 kg
-Calculate the weight of the body
weight = mass x gravity
-Substitution
weight = 169.92 x 9.82
-Simplification
weight = 1666.9 N ≈ 1667 N

Answer:
The value is 
Explanation:
From the question we are told that
The molar mass of hydrazine is 
The initial temperature is 
The final temperature is 
The specific heat capacity is ![c_h = 0.099 [kJ/(mol K)] = 0.099 *10^3 J/(mol/K)](https://tex.z-dn.net/?f=c_h%20%20%3D%20%200.099%20%5BkJ%2F%28mol%20K%29%5D%20%3D%200.099%20%2A10%5E3%20J%2F%28mol%2FK%29)
The power available is 
The mass of the fuel is 
Generally the number of moles of hydrazine present is
=> 
=> 
Generally the quantity of heat energy needed is mathematically represented as
=> 
=> 
Generally the time taken is mathematically represented as
=> 
=> t = 2480505.6377 s
Converting to hours
