Answer:
177.993 MeV
Explanation:
Nuclear fission refers to a process where a nucleus is broken into smaller ones.
m(Am) = 242.0595490 u, m(Sr) = 89.9077387 u, m(La) = 148.934733 u and m(n) = 1.008665 u. To find the mass of X, we sum up the masses on both side and subtract them according to the equation given
242 + X = 90 +149 + 4
X = 243 - 242 = 1
so X is a neutron
next we calculate the Δm ( change in mass)
Δm = mass reactant - mass of product
(242.0595490 + 1.008665 ) - ( 89.9077387 + 148.934733 + 4 (1.008665))
= 243.068214 - 242.8771317 = 0.1910823 u
using the formula
E = (Δm) c² = 0.1910823 u × c² × 
× 
= 177.993 MeV
Sorry but I can’t help you. The image is blurry and therefore the supposition is incorrect . But 12/4 equals 3
Answer:
Newton's first and third law of Motion
Explanation:
The laws applying in the example Newton's first and third laws of Motion.
- The first law states that any object at rest (ie. not moving) will stay at rest until it is forced to move by an external force. In this case, said force were the propulsion gases ignited.
- As the hot gases were pushed out from the engine nozzle, there was another force <em>equal in magnitud but opposite in direction</em> (as the gases went down, that force went upwards), said force is directly responsible for the rocket taking off. That is an example of the third law.
0 because you would be floating at the top within seconds and also have fun with the sudden stop
The Largest. There are 17 bodies in the solar system whose radius is greater than 1000 km. The composite above shows the Sun and the 5 largest planets at a scale of 3200 km/pixel. (Earth<span> is the tiny spot between Jupiter and the Sun) so the sun is the largest body in our solar system. hope this helped! ^^</span>
