Answer:
4.41 W
Explanation:
P = IV, V = IR
P = V² / R
Given that P = 0.0625 when V = 1.50:
0.0625 = (1.50)² / R
R = 36
So the resistor is 36Ω.
When the voltage is 12.6, the power consumption is:
P = (12.6)² / 36
P = 4.41
So the power consumption is 4.41 W.
Answer:
neutral
Explanation:
3p - 3e = 0 and that leaves 2 neutrons so it will be neutral
Answer:
Explanation:
The fusion reaction in this problem is
The total energy released in the fusion reaction is given by
where
is the speed of light
is the mass defect, which is the mass difference between the mass of the reactants and the mass of the products
For this fusion reaction we have:
is the mass of one nucleus of hydrogen
is the mass of one nucleus of helium
So the mass defect is:
The conversion factor between atomic mass units and kilograms is
So the mass defect is
And so, the energy released is:
Answer:
Before fueling the tank.
Explanation:
All the stated concerns such as the condition of fuel line and fuel vents should always be checked before fueling the tank.
While fueling the tank make sure not to fill it up to brim. Doing this may gets to blast as fuel when heated will not have any space to expand. Fuel vent must be in good condition as it release vacuum and pressure build inside the tank.
Fuel lines helps to move to move fuel from one place to another, hence any damage or leakage in this can result into a big collapse so all these must be properly checked.
The radioactive isotope that would take the least amount of time to become stable is rubidium-91. This is because this isotope is the most stable compared to the rest. This was determined by subtracting its atomic mass by its atomic number. The isotope with the least number of difference is the most stable, while the one with the greatest difference is the most unstable.
Difference:
Rubidium: 54 (most stable)
Iodine: 78
Cesium: 80
Uranium: 146 (least stable)
