Answer:
Speed = 0.866c
Where c is speed of light
Explanation:
We want to find the speed at which it run at a rate that is one-half the rate of a clock at rest.
Thus, we will use time dilation equation to solve it.
Thus;
t_o/√[1 - (v²/c²)] = 2t_o
Where:
t_o is time at rest
v is the speed at which it runs
c is the speed of light.
t_o will cancel out to give;
1/√[1 - (v²/c²)] = 2
Rearranging, we have;
√[1 - (v²/c²)] = ½
Let's make v the subject of the formula;
Let's square both sides to get;
1 - (v²/c²) = ½²
1 - (v²/c²) = ¼
Rearrange to get;
1 - ¼ = v²/c²
¾ = v²/c²
Take square root of both sides to get;
v/c = √¾
v = c × 0.866
v = 0.866c
Answer:
primul_copil = int(input("Introduceți vârsta primului copil: "))
aldoilea_copil = int(input("Introduceți vârsta celui de-al doilea copil: "))
def copilmai_mare(varsta1, varsta2):
if varsta1 > varsta2:
diferenta = varsta1 - varsta2
print("copilul mai mare este varsta1 cu diferența de vârstă de: ", diferenta )
else:
diferenta = varsta2 - varsta1
print("copilul mai mare este varsta2 cu diferența de vârstă de: ", diferenta )
copilmai_mare(primul_copil, aldoilea_copil)
Explanation:
Programul python de mai sus definește o funcție "copilmai_mare" care ia două argumente "varsta1" și "varsta2". Diferența dintre vârstele copiilor este comparată, iar cel mai mare copil și diferența sunt tipărite pe ecran.
Answer:
explain all background information first.
Explanation:
Now if you are to deliver a message and you have suspicions that the person who is to read it might be uninterested, unwilling, hostile or displeased, you should put the main idea later in the message. That is, it should come after you have provided details given explanations or evidence.
It is not right to start with bad news. As a matter of fact bad news should not be shared through mails, IM or texts.
