To calculate the mass of the fuel, we use the formula

Here, m is the mass of fuel, V is the volume of the fuel and its value is
and
is the density and its value of 0.821 g/mL.
Substituting these values in above relation, we get
Thus, the mass of the fuel 247 .94 kg.
Answer:
the size, length, or amount of something, as established by measuring.
Answer:
The angular momentum of the particle is 58.14 kg m²/s along positive z- axis and is independent of time .
Explanation:
Given that,
Mass = 1.70 kg
Position vector 
We need to calculate the angular velocity
The velocity is the rate of change of the position of the particle.



We need to calculate the angular momentum of the particle
Using formula of angular momentum

Where, p = mv
Put the value of p into the formula

Substitute the value into the formula



Hence, The angular momentum of the particle is 58.14 kg m²/s along positive z- axis and is independent of time .
The gravitational force will double as well because
F=mg
