After an elastic collision, the blue puck has a velocity of 2i – 2j m/s. What is the velocity of the gold puck after the collision?
A. 2i –j m/s
B. 3i –j m/s
C. 2i – 2j m/s
D. 3i – 2j m/s
The velocity of the gold puck after the collision be (2i - j) m/s.
What is velocity?The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.
Given parameters:
Mass of the gold puck: m = 12 kg
Velocity of it before collision: u = 5i – 4j m/s.
Mass of the stationary blue puck: M = 18 kg.
Velocity of it after collision; V = 2i – 2j m/s.
We have to find: the velocity of the gold puck after the collision: v = ?
From conservation of linear momentum, we get:
Total momentum of the system before collision = Total momentum of the system after collision
⇒ mu + M.0 = mv + MV
⇒ v = u - MV/m
⇒ v = (5i – 4j) m/s - (2i – 2j)m/s×18/12.
⇒ v = (5i – 4j) m/s - (3i - 3j) = (2i - j) m/s.
Hence velocity of the gold puck after the collision be (2i - j) m/s.

why might a CD be a more reliable way to copy and distribute a sound recording than a vinyl record
Answer:
Is either b or d
Explanation:
A CD be a more reliable way to copy and distribute a sound recording than a vinyl record because a CD is easier to copy exactly over and over again.
What are CDs and vinyl records?CDs are digital music storage devices, which means the music is binary data encoded. It uses a 2-channel, 16-bit, 44.1 kHz configuration as the norm for CDs. A laser reads the data, and after it has been decoded, audio is played back.
A sensitive needle known as a stylus is used to read the physical record of the music that is imprinted on the vinyl disc because vinyl is an analogue storage medium. The 12-inch 33-rpm LP, 7-inch 33-rpm EP, and 7-inch 45-rpm single make up the typical vinyl album.
The diameter and playback speed are what determine a vinyl disc's storage capacity (larger discs and slower playback means more capacity). The stereo channels are divided among the groove's two sides.
Hence, option (D) is correct.

You have about 10 quarts of blood in your body. At REST your heart pumps about 5 quarts each minutes. That is half of your blood volume per minute. During exercise it can pump 40 quarts per minute. How many times does all of your blood complete the cycle around your body during exercise?
Answer:
8 times
Explanation:
Given that You have about 10 quarts of blood in your body. At REST your heart pumps about 5 quarts each minutes.
That means the heart will pump 10 quarts in 2 minutes.
That is half of your blood volume per minute.
If during exercise it can pump 40 quarts per minute, that is, 80 quarts in 2 minutes.
To know how many times does all of your blood complete the cycle around your body during exercise, you must divide 80 quarts by 10 quarts. That is,
80 / 10 = 8
Therefore, your blood complete the cycle around your body 8 times during the exercise.

A car accelerates uniformly from rest to a speed of 6.6 m/s in 6.5 s. Find the acceleration the car presents during this time?
Answer:
1.02 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 m/s
Final velocity (v) = 6.6 m/s
Time (t) = 6.5 s
Acceleration (a) =.?
Acceleration can simply be defined as the change of velocity with time. Mathematically, it can be expressed as:
a = (v – u) / t
Where:
a is the acceleration.
v is the final velocity.
u is the initial velocity.
t is the time.
With the above formula, we can obtain the acceleration of the car as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 6.6 m/s
Time (t) = 6.5 s
Acceleration (a) =.?
a = (v – u) / t
a = (6.6 – 0) / 6.5
a = 6.6 / 6.5
a = 1.02 m/s²
Therefore, the acceleration of the car is 1.02 m/s²
why are force and velocity different?
Answer: If you apply force to an object the velocity changes. But it doesn't work the other way around apply velocity and the force (no!) Velocity does not change on an object. A force pushes or pulls on an object, but velocity is simply something an object has I hope this makes sense to you. Hope this helps :)

Why does an object slow down when going uphill
Please explain properly
Answer:
The change in speed on slopes is due to gravity. When going downhill, objects will accelerate (go faster), and when going uphill they will decelerate (slow down). On a flat surface, assuming that there is little friction, they will then maintain a constant speed.

Moral Dilemma A man is sitting at home worrying about the fact that his daughter needs a major surgery in order to continue living, but he does not have the money to pay for it. He has asked family and friends to help with the cost of the surgery, but he was only able to raise about a quarter of what the surgery costs. He then remembers that he has power of attorney (i.E., control over someone else's finances/legal issues) for his out-of-touch-with-reality, but healthy, 85-year-old father. The man could, without anyone knowing, use his father's money to pay for the surgery. However, this would leave his father with only one year of living expenses. The man decides to take his father's money for his daughter's surgery. Should the man have done that? Why?
Answer:
Mostly with aid of Kohlberg 's moral growth theory, I clarify this answer, which would also be separated into three stages under which this particular problem is illustrated below.
Explanation:
Pre conventional Stage:The daughter's father would think about either the penalty during that point if he commits any wrongdoing or breaches laws to save her daughter. But another way to make that happen for surgery is that a person cares about either the legislation and rules as well as the significance of respecting them throughout the pre-conventional process. He will also attempt to establish its insight into solving these problems.
Conventional Stage:As per the traditional process of the spiritual psychosocial development of Kohlberg, her father would think of civilization because there are conventions that unless he borrows money of his dad again for the procedure of their daughter, culture would label him greedy or prejudice against him to pay the profits of his father despite his consideration.
Post conventional Stage:As per this argument, he might determine for her child as well as father in his philosophy including perspectives, which means that his father is not in the situation of requesting credit, but because he's in a position to give a recommendation, therefore he certainly gives authorization rescue her grandchildren even though she is small and has several activities to do in hers life. And subsequently, with emerging profits, he will take care of his father as well as daughter, and nowadays focus says their daughter wants treatment to recover.
