How did Marie Curie’s research in radioactivity benefit others while harming her

Answers

 The discoveries Mme Curie made were of great benefit to physics, chemistry and medicine. During the time she was doing her research, the health effects of ionizing radiation were not known. The amount of radiation that she was exposed to led to her death. Even today her notebooks and other personal effects are highly contaminated with radioactive material. 

Which is NOT a characteristic of background radiation?A.) It is generally safe
B.) It includes cosmic rays
C.) It burns and causes lung cancer
D.) It occurs naturally in the environment

Answers

The one among the following choices that is not a characteristic of background radiation is that it burns and causes lung cancer. The correct option among all the options that are given in the question is the third option or option "C". The other options given in the question are all true in case of background radiation.

Answer:

C.) It burns and causes lung cancer

Explanation:

After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. Which kind of decay has occurred, and how do you know? alpha decay because alpha particles have no mass beta decay because this kind of decay cannot change one element into another alpha decay because it creates a new isotope of the same element gamma decay because photons have no mass.

Answers

Gammadecay is the production of extremely high-frequency electromagnetic radiation . Gamma decay is the right answer from all types of decay.

What is gamma-decay?

Gammadecay is the production of extremely high-frequency electromagnetic radiation in order to stabilize the unstablenucleus. You must be well-versed in the various energylevels found in an atom.

The Nucleus has its own amount of energy. Gamma decay is the nucleus' method of transitioning from a higher energy level to a lower energy level by emitting high energy photons.

Hence gamma decay is the right answer for all types of decay. Because photons have no mass.

To learn more about gamma decay refer to the link;

Answer:

D. gamma decay because photons have no mass

Explanation:

a ball is dropped from rest at a height of 80 m above the ground. what is the speed just as it hits the ground?

Answers

Δx=Vi(t)+.5at²
Δx=80
a=9.8
Vi=0 since its from rest, the initial velocity is 0.
80=0+.5(9.8)t²
t=16.33
You can use one of the big five equations: Vf=Vi+at
Vf=0+9.8(16.33)
Vf=160.034 m/s

The mass of a moving object increases, but its speed stays the same. What happens to the kinetic energy of the object as a result?It decreases.

It increases.

It remains unchanged.

It fluctuates up and down.

Answers

It increases.
Hope this helps.
We Know, K.E. = 1/2 × m × v²
From the expression, we can conclude that Kinetic energy is directly proportional to mass. So, as mass will increase, Kinetic energy will also increase.

In short, Your Correct answer would be Option B

Hope this helps!
