Answer:
Because of the revolution of the moon about the earth.
Explanation:
The moon is the natural satellite of the earth; which rotates about its axes and orbits around the earth. As the moon orbits the earth with respect to time, it would complete a revolution in 27.3 days.
During revolution, different phases of the moon can be observed by someone on the earth. This is due to its location at different time during the process. Therefore, Jorge was able to see different phases of the moon because of its revolution about the earth.
In a nuclear fission reaction, a freely moving neutron is introduced to a nuclear fuel, then a neutron is absorbed by an atom's nucleus.
<h3>What is nuclear fission?</h3>
Nuclear fission is a process in which an unstable nuclei will convert into stable nuclei after releasing the energy in the form of particles.
When we introduce a freely moving neutron to the nuclear fuel of uranium-235 nuclei then this introduced neutron was absorbed by the nuclei and makes the nuclei more unstable. Then this unstable nuclei will convert into two nuclei in the addition of three neutrons.
Hence, a neutron is absorbed by an atom's nucleus.

Speed is equivalent to the distance traveled divided by the time it takes to travel that certain distance.
To solve this problem convert the units first from meter and yards to miles. 100 metes is 0.0621371mi and 100 yards is 0.0568182 yard. 9.69s = 0.002691667 hr and 9.21s = 0.002558333
A.) 23mi/hr
B.) 22.20mi/hr
Answer:
P₂ = 0.11 atm
Explanation:
Given data:
Initial pressure = 0.12 atm
Initial temperature = 294 K
Final pressure = ?
Final temperature = 273 K
Solution:
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
0.12 atm / 294 K = P₂/273 K
P₂ = 0.12 atm × 273 K / 294 K
P₂ = 32.76 atm. K /294 K
P₂ = 0.11 atm
