Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
Answer:
Particle A: K.E = 38.3 J
Particle B: K.E = 7.67 J
Explanation:
Given that Particle A and particle B are held together with a compressed spring between them. When they are released, the spring pushes them apart, and they then fly off in opposite directions, free of the spring. The mass of A is 5.00 times the mass of B, and the energy stored in the spring was 46 J. Assume that the spring has negligible mass and that all its stored energy is transferred to the particles. Once that transfer is complete, what are the kinetic energies of each particle?
The total kinetic energy of Particle A and particle B should be equal to 46 J
Since the mass of A is 5.00 times the mass of B, then, the K.E energy of each particle can be calculated by using ratio.
5 + 1 = 6
K.E for particle A
5 /6 × 46 = 230 / 6 = 38.3 J
K.E for particle B
1/6 × 46 = 46 / 6 = 7.67 J

how does the sun rise and set
a.earth orbit around the sun
b.The sun is center of solar system
c.earth rotates on it tilted axis and orbit around the sun at the same time
Answer:
c. earth rotates on it tilted axis and orbit around the sun at the same time
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun. Thus, this makes us to experience day and night (sun rise and sun set) due to the rotation of planet about its axis.
Hence, the sun rise and set because the earth rotates on it tilted axis and orbit around the sun at the same time

What happens to the force between two charged particles if the distance between them is cut in fourth?
Answer: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if the distance between charges is halved (charges remaining kept constant), the force between the two charges is quadrupled.
Explanation: hope i helped c;

Explain how height, acceleration, and speed would affect the movement of a roller coaster.
Answer:
height affects the acceleration, which means it could go faster at the end of the slope since it got more distance to travel. acceleration could affect the speed of the roller coaster because it will go faster as it approaches the end of the slope and speed can affect the height it reaches because the faster it goes, the more distance it can travel before reaching to a stop.

Answer: Kinetic Energy
Explanation:
Julio decides to break the Guinness Book of World Records for bungee jumping. He goes
to the Macau Tower in China where the current record is held. After several heart-pounding
seconds, he leaps from a height of 233 meters. If his weight is 86 kilograms, what would his
potential energy be just prior to jumping? If when he jumped he reached a speed of 15 m/s, what
is his kinetic energy? Explain your answer
Answer:
a) U = 1.96 10⁵ J, b) K = 9.675 10³ J
Explanation:
a) the potential energy is
U = m g h
where zero energy in general takes the floor
let's calculate
U = 86 9.8 233
U = 1.96 10⁵ J
b) They ask for kinetic energy and give us the speed of man
K = ½ m v²
let's calculate
K = ½ 86 15²
K = 9.675 10³ J

A circle graph shows that one-fourth of the students in a particular school ride the bus every day. What is this equivalent measurement in radians? In degrees?
Answer:
it's 1.57... radians and 90°
As par circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.
What is circle graph?Pie charts are another name for circle graphs. The graph is shaped like a circle, with many wedges that each represent a portion of the overall.
The circle graph is commonly referred to as a pie chart since these wedges frequently resemble pie slices. The circle graph's angles are proportionate to the quantity they each represent.
According to circle graph:
Total number of student in the particular school = 2π radian.
So, one-fourth of total number of student in the particular school = 2π/4 radian
= π/2 radian.
Hence, according to circle graph, π/2 radian part of total number of the students in a particular school ride the bus every day.

period of his oscillation?
(Unit = s)
Answer:
5.02s
Explanation:
I got it right in acellus :)
The period of the oscillation when Tarzan is swinging back and forth so it should be 5.01 seconds.
Calculation of the period:Since
Length L = 6.25 m
g = 9.8 m/s²
So,
T = 2π√(L/g)
T = 2π√(6.25 / 9.8)
T = 5.01 sec

A steel fork and a plastic spoon are both at the same temperature. The fork feels colder when you touch it. This is because:
1. Steel conducts thermal energy better than plastic.
2. Plastic loses more thermal energy than steel.
3. Steel contains more thermal energy than plastic.
4. The fork has more mass than the spoon.
Answer: The fork feels colder when you touch it because Steel conducts thermal energy better than plastic. The correct statement is 1
Explanation:
The ability of a material to transfer heat energy in an environment is known as thermal conductivity. It feels cooler to touch a steel spoon than a plastic spoon found in the same temperature because steel which is a type of metal is a highly efficient thermal conductor than spoon which is a plastic.
Metals can be defined as those substances which forms positive ion in a chemical reaction by lossing it's electrons. It has the following properties:
--> it is solid at room temperature
--> it has high melting point
--> it has high boiling point and
--> it is malleable.
Metals are said to be good thermal conductor because they contain free flowing conduction electrons. Therefore, when you touch a steel spoon and plastic spoon, it feels cooler because the steel metal is able to conduct heat away from your hand faster than the plastic which is a poor conductor of heat.
Answer:
1. Steel conducts thermal energy better than plastic.
Explanation:
Both objects are at the same temperature, and when you touch them, you feel the steel to be colder.
This happens because steel is a better thermal conductor, then when you touch it, it "steals" more thermal energy from you than the plastic.
As the amount of thermal energy transmitted is greater for the steel, you will feel it to be colder.
Then the correct option is the first one, steel conducts thermal energy better than plastic.

Velocity can be described as the same thing as speed but with _________________ included
Answer:
Direction
Explanation: Hope this helps!
Answer:
nvm its direction :))
Explanation:
Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.
Velocity is a measure of both speed and direction of motion. Velocity is a vector, which is a measurement that includes both size and direction. Velocity can be represented by an arrow, with the length of the arrow representing speed and the way the arrow points representing direction.
