Answer:
c. Fission and fusion are two processes that release very little amounts of energy.
Explanation:
This statement is false. In fact, both fission and fusion are processes which release very large amounts of energy. The statement can be rewritten as it is true as follows:
"Fission and fusion are two processes that release very large amounts of energy."
Fission occurs when a large nucleus break apart, splitting into smaller nuclei, while fusion occurs when two light nuclei combine together into a larger nucleus. In both cases, the mass of the reactants is larger than the mass of the final products, so some of the mass has been converted into energy, according to Einstein's equation:
where
E is the energy released
is the mass lost in the process
c is the speed of light
Since c is a very large number (), we see that even a very small mass causes the released of a huge amount of energy, so both fission and fusion release large amounts of energy.
Answer:
Explanation:
Speed is a scalar quantity and it doesn't depend on direction
Speed is the total distance traveled divided by the total time taken
Speed = Total Distance / Total time taken
Given that,
A plane can traveled 3952 km in 3 hours normally.
So, it's normal speed is
Speed = total distance / total time
Speed = 3952 / 3
Speed = 1317.33 km/hr
Now, in cloudy skies it will traveled 184 km less than it's usually distance in the same time range.
Then, we want to find the speed in cloudy skies
Since we know that speed is total distance divide by total time,
We need to know the total distance in cloudy skies
Total distance = Normal distance travelled — delay due to cloudy skies
Total distance. = 3952 - 184
Total distance = 3768 km
Total time = 3 hours
Then,
Speed = total distance / total time
Speed = 3768 / 3
Speed = 1256 km/hr
The speed of the plane in cloudy skies is 1256 km/hr. The speed reduces because it traveled less distance for the same time.
Answer:
it will double because im right
There actually three assertions here: one in A and two more in B.
All three assertions, as well as the reasoning described in this mess, are all False.
The correct choice from the list is e), but that doesn't even describe the complete Falseness of this disaster.
