Spring is stretched by force f to distance "x"
now here by force balance we can say
now here we will we say that energy stored in the spring will convert into kinetic energy
now solving above equation we will have
PART 2)
now for half of the extension again we can use energy conservation
now the speed is given as
Answer:
cell swell and burst(b)
Explanation:
This process is called hemolysis. it also occurs in a red blood cell.
The wavelength of the laser beam in the liquid is 517 nm

One advantage of using primary sources when doing research on an experiment is, it contain more details about the experiment. Thus, option D is right .
To find the answer, we have to know more about the Primary sources.
<h3>
What is the advantages of primary sources?</h3>
- Primary sources are the direct or first-hand excerpts that scientists have independently written based on their experiments in order to support their research.
- Utilizing original sources encourages analytical and critical thought in relation to the research.
- It aids in exploring from various angles, which leads to the discovery of extra facts.
- Primary data aids in navigating the conflicts. Since it is a direct resource related to the experiment, it serves as evidence for the data.
Thus, we can conclude that, Primary sources contain more details about the experiment.

A )
t 1 = 2 h, t 2 = 6 h
Δ t = t 2 - t 1 = 6 - 2 = 4 h
54 = 50 + a Δ t
54 = 50 + 4 a
4 a = 54 - 4
4 a = 4
a = 4 : 4
a = 1 km/h²
v o = 48 km/h
An equation that can be used to describe the velocity of the car at the different times is:
v = 48 + t
B ) The graph is in the attachment.
