How does the space shuttle maneuver in exosphere

1 answer:

8 0

In a rocket combustion chamber the rocket exhaust is forced out of the nozzle by the rapid expansion of exhaust gases and the directing shape of the rocket nozzle. The equal and opposite reaction is that the rocket nozzle (and hence the shuttle it is attached to) is forced in the other direction

If the rest energies of a positive sigma particle and a lambda particle are 1189.4 and 1115.7 Mev respectively, what is the diff

Lunna [17]

Answer:

1.31022×10⁻³⁴ kg

Explanation:

Difference in energies = 1189.4-1115.7 MeV = 73.7 MeV

Convert this energy to Joules

1 MeV = 1.6×10⁻¹⁹ J

73.7 MeV = 73.7×1.6×10⁻¹⁹ J = 117.92×10⁻¹⁹ J

c = Speed of light = 3×10⁸ m/s

From Einstein's equation

E = mc²

$m=\frac{E}{c^2}\\\Rightarrow m=\frac{117.92\times 10^{-19}}{(3\times 10^8)^2}\\\Rightarrow m=1.31022\times 10^{-34}\ kg$

∴ Difference in their masses is 1.31022×10⁻³⁴ kg

When looking for a mathematical relationship between two variables what graph do you use?

Mnenie [13.5K]

I believe the correct answer from the choices listed above is option A. When looking for a mathematical relationship between two variables, use a line graph. It relates how one variable affects the other by a linear relationship.

Hope this helps.
