Answer:
15193.62 m/s
Explanation:
t = Time taken = 6.5 hours
u = Initial velocity = 0 (Assumed)
m = Mass of rocket = 1380 kg
F = Thrust force = 896 N
v = Final velocity
a = Acceleration of the rocket
Force
Equation of motion
The velocity of the rocket after 6.5 hours of thrust is 15193.62 m/s
Answer:
not allow electricity to pass through it
Explanation:
One example of an insulator is rubber. That's why rubber is used on many electrical cables. Hope this helped.
Answer:
1) Addition of a catalyst
2) To change the reaction rate of slope B to look like slope A, simply add a catalyst to speed up the rate of reaction, giving you a higher amount of products in a shorter amount of time (line A)
Explanation:
1 and 2)Two things can alter the rate of a reaction, either the addition of a catylist which will not alter the composition of the products or reactants, but will accelerate the reaction time, or an increase in temperature will also increase the rate at which a reaction will occur.
You could choose temperature also and have the same result, it's your choice both are correct, but catalyst is the easiest.
Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that
Potential well dimension =
Mass of electron
So energy required to electron to jump from ground state to 3rd state
