The instantaneous velocity of the 15 kg. mass just after collision can be found by the principle of linear momentum.
a) The speed of the 15 kg. just after collision is 2 m/s.
b) The type of collision is inelastic collision
c) The compression of the spring is approximately 0.323 m.
Reasons:
The given parameters are;
Mass of the block attached to the spring, m₁ = 15.0 kg
Force constant of the spring, K = 575 N/m
Mass of the stone that strikes the block, m₂ = 3.00 kg
Speed of the stone, v₂ = 8.00 m/s
Speed with which the stone rebounds, v₃ = 2.00 m/s
a) The total initial momentum = 3 kg. × 8 m/s = 24 kg·m/s
The final momentum, just after collision = 3 × (-2) kg·m/s + 15 kg ×v₁
By conservation of momentum, we have;
24 kg·m/s = 3 × (-2) kg·m/s + 15 kg ×v₁
[tex]v_1 = \dfrac{24 \, kg \cdot m/s + 6 \, kg \cdot m/s}{15 \, kg} = 2 \, m/s[/tex]
The speed of the 15 kg. just after collision, v₁ = 2 m/s.
b) A collision is elastic when the kinetic energy of the collision is conserved
The initial kinetic energy, K.E.₁ = 0.5 × 3 kg. ×(8 m/s)² = 96 J
The sum of the final kinetic energy are;
0.5 × 3 kg. × (2 m/s)² + 0.5 × 15 kg × (2 m/s)² = 36 J
The initial kinetic energy ≠ The final kinetic energy
Therefore, the collision is not elastic
(c) The kinetic energy given by the block = The elastic potential energy gained by the spring
Kinetic energy of the block, K.E. = 0.5 × 15 kg × (2 m/s)² = 30 J
Elastic energy gained by the block = 0.5 × K × x² = 0.5 × 575 N/m × x²
Therefore;
0.5 × 575 N/m × x² = 30 J
[tex]x^2 = \dfrac{30 \, J}{0.5 \times 575 \, N/m} = \dfrac{12}{115} \, m^2[/tex]
[tex]x = 2 \cdot \sqrt{\dfrac{3}{115} } \approx 0.323[/tex]
The compression of the spring, x ≈ 0.323 m.

Answer:
City States.
Explanation:
Wealthy merchants such as Cosimo de’ Medici ruled Italian churches to city states.
What is City states?Ancient Greece had a polis, or city-state, form of government. Each city-state was set up with an urban core and the countryside surrounding it. In a polis, the city was enclosed by protective outside walls and included public areas with temples and governmental structures.
The summit of a hill, or acropolis, was frequently where the temples and political structures were erected. The well-known Parthenon in Athens is an iconic example of a monument that was the focal point of an ancient acropolis.
A temple dedicated to the goddess Athena was called the Parthenon. Since the city served as the epicenter of trade, commerce, culture, and political action, the bulk of people in a polis lived there.
Therefore, Wealthy merchants such as Cosimo de’ Medici ruled Italian churches to city states.

If she saves her money and pays cash, she can purchase a refrigerator in .
Answer:
Explanation:
Maria will pay an extra amount of $924 to &951 to buy the television, rather than waiting until she saves up enough money to pay cash for it.
If Maria saves her money and pays cash, she can own a refrigerator in 4 months.
There are 52.3 weeks in a year, and depending on when she buys it, she can manage to make 52 or 53 payments that would make a total of $1404 a year or $1431 a year, if paying cash is $480, the difference would be either $924 or $951.
The refrigerator costs $800 and with the budget, she has a month, she can buy one after 4 months.

Read the quote from President Wilson’s letter to the National Child Labor Committee. "As the labor situation created by the war develops I am more interested than ever, if that were possible, in throwing all the safeguards possible around the labor of women and children." The "labor situation" Wilson refers to most likely concerned him because: going to war meant US industry had to begin manufacturing military supplies. women and children had to do the jobs of male workers who became soldiers. no one was left to support families when men enlisted and went to war. women and children had to replace striking factory workers.
Answer:
B
Explanation:
Women demonstrated that they could perform “men's work” to a high standard during the Second World War. Thus, option C is correct.
What are the labor situation referred by Wilson?Wilson backed and signed into law the Adamson Act, which secured an eight-hour workweek for railroad workers after American railroad unions threatened to strike in 1916. This act paved the way for shorter workdays for all industrial workers.
When males were recruited to military duty and the demand for war materials increased, women were granted access to manufacturing jobs.
For the soldiers, they made blankets, fixed shoes, laundered clothing, and sewed uniforms. Giving sick and injured soldiers medical attention during the conflict was arguably the most significant role played by women.
Therefore, women and children had to do the jobs of male workers who became soldiers.

Which action by one of the students is most disruptive to the discussion? One listener interrupts the speaker by inserting an opinion. One student laughs at the opinion presented by another student. One listener maintains eye contact with the speaker. The teacher calls on the next student to express a viewpoint.
Answer:A
Explanation:One listener interrupts the speaker by inserting an opinion.
One of the main things that prevents people from listening is noise, which is anything that makes it difficult to pay attention to and comprehend what is being spoken. Thus, option A is correct.
What are the interrupts affecting the listener by opinion?The act of interjecting communicates to the speaker your disinterest in what they have to say. You don't have time to actually listen to them or believe your voice is more essential.
It might even give the impression that you weren't paying attention at all and were simply waiting for an opportunity to speak.
Frequent interruptions can also double error rates, increase rates of tiredness, and stress-related illnesses. The next time you are tempted to interrupt a coworker who is hard at work with a brief comment, consider the effect you will have.

a box contains 10 equal-sized balls, numbered 1 to 10. two balls are drawn at random simultaneously. what is the probability that the numbers on the two balls will differ by more than 2?
The probability that the two balls are chosen will differ by more than 2 is 43/45
Probability is the likelihood or chance that an event will occur.
If a box contains 10 equal-sized balls and 2 balls are chosen at random from the box, the total outcome will be expressed as:
[tex]10C_2=\frac{10!}{(10-2)!2!}\\ 10C_2=\frac{10!}{8!2!}\\10C_2=\frac{10\times 9 \times 8!!}{8!2!}\\10C2=\frac{90}{2} =45 ways[/tex]
If the number on the two balls chosen will differ by less than or equal to 2, the expected outcomes are (1, 2), (1, 3) that is 2 outcomes
The probability that the two balls are chosen will differ by less than or equal to 2 is 2/45
The probability that the two balls are chosen will differ by more than 2 is 1 - 2/45 = 43/45
