Answer:
= 1,386 m / s
Explanation:
Rocket propulsion is a moment process that described by the expression
- v₀ = ln (M₀ / Mf)
Where v are the velocities, final, initial and relative and M the masses
The data they give are the relative velocity (see = 2000 m / s) and the initial mass the mass of the loaded rocket (M₀ = 5Mf)
We consider that the rocket starts from rest (v₀ = 0)
At the time of burning half of the fuel the mass ratio is that the current mass is
M = 2.5 Mf
- 0 = 2000 ln (5Mf / 2.5 Mf) = 2000 ln 2
= 1,386 m / s
Answer:
Please see the attached picture for the complete answer.
Explanation:
390, the force of gravity is 10 N on Earth, so you would divide 3900 by 10
D cause u can measure how powerful that wave was
Answer:
Explanation: Peripherial arterial disease is a blood circulation disorder which occurs when the blood vessels outside the heart and brain to block or spasm. This is as a result of the pulse decreasing rather than increasing in amplitude.
