Hello, Classmates!
World War II or Sputnik? According to Cassidy (2011), in reaction to the launch of the Soviet Sputnik satellite in 1957, the number of scientists/engineers and physicists/astronomers tripled. This historical event presented an outstanding opportunity for the advancement of the knowledge and advancement of physics. Although it was men who took over the industry, women quadrupled in both categories. This event spun people's heads to go out of their way and fight for a career to achieve something extraordinary for their country.
Part II
Do you feel that the knowledge of how to split an atom is good or bad for society?
If I was asked, is the knowledge of splitting an atom is good or bad for the world? Most definitely bad, and must be off the plant if we must. As a society, good, we need protection and must be knowledgeable to take precautions. It created an opportunity for society to expand from chemists to physicists. Splitting an atom was a race to create a massive explosion and obstruct someone's world. World War II opened the door to physicists as a defense mechanism, raising a fund to build a bomb after the Peal Habor attack (Cassidy, 2011). The attack kept everyone on their toes as it was a horror scene, and initiative actions needed to remain in the fighting field from a political standpoint.

An isotope of a radioactive element has half-life equal to 9 thousand years.
Imagine a sample that is so old that most of its radioactive atoms have decayed, leaving just 25 percent of the initial quantity of the isotope remaining.
How old is the sample?
Give your answer in thousands of years, correct to one decimal place.

A certain radioactive material has a half-life of 8 minutes. Suppose you have a large sample of this material , containing 10^25 atoms. 5x10^24 atoms decay in the first 8 minutes and 2.5x10^24 atoms decay in the second 8 minutes. What is the ratio of the number of atoms that decay in the first 8 minutes to the number of atoms that decay in the second 8 minutes

Question
Hello,I wanna asked if my answer is correct...
For A to B I am using Ta+Va=Tb+Vb
And I get
Ta= 0 since there is no velocity
Tb = ½(50)(VB)²=25(VB)²
Va=½ks² = ½(2000)(0.6)² =600N
Vb=mgh =(50)(9.81)(0.9)= 441.45
Then Vb =2.52 m/s
And then using vertical motion from b to c to find t
Y=Y initial+(V sin36.87)tBC+1/2a(tBC)²
Then t = 0.609s
And find d using d=(vcos36.87)t
d=1.23m
Is my answer and method correct? Sorry for my bad english

A light year (LY) is the distance that light travels in one year.
1 LY = 9.46x1015 m.
Suppose we have detected a planet that orbits a star that is 104 light
years away. How many millions of years would it take us to get there if
we used a modern rocket with a maximum speed of 20.0 km/s (about
45,000 mph)? Assume 3 sig figs.

Oxygen Atoms in People. Figure 5.7 shows that oxygen makes up about 65% of the mass of a human being. A single oxygen atom has a mass of 2.66 × 10−26 kg. (a) Use this fact to estimate the number of oxygen atoms in your body. (Hint: If you know your weight in pounds, you can convert to kilograms by dividing by 2.2.) (b) Compare your answer to the number of stars in the observable universe (which is roughly 1022).

In daily life, we see many cases of people who are caught misrepresenting things and who soon thereafter are excused and accepted by their contemporaries. How is this different in science?
