A billiard ball collides with a second identical ball in an elastic head-on collision. What is the kinetic energy of the system after the collision compared with the kinetic energy before the collision
Answer:
Explanation:
From the question, we were made to understand that the collision between the two billiard balls was an elastic collision. Hence, an elastic collision is one in which the kinetic energy is conserved. Meaning the kinetic energy before the collision is still retained after the collision.
Kinetic energy before collision = kinetic energy after collision

Explain how the Law of Conservation of Energy applies to the energy
transformations that occur from the outlet charger to the ringing phone.
Answer:
The mobile electric energy gets converted into chemical energy while charging.
Explanation:
According to the law of conservation of energy, no energy is destroyed when one form of energy is transformed to another in the process as energy cannot be created or destroyed. As a result, total amount of energy remains same before and after any kind of transformation.
Generally, lithium ion batteries are used in mobile phones. In such batteries, the electricity is stored in the ionic structure by the chemical changes.
The mobile electric energy gets converted into chemical energy while charging.
Radioactive iodine (radioiodine) is given to patients with some forms of thyroid cancer in order to destroy the cancer cells. 1311 has a half-life of 8
days. Women who have been treated with 1311 are advised to not become pregnant for 180 days (approximately 6 months) to avoid the
radioactive contamination of a developing fetus.
If a woman has been given a dose of 10 mCi (millicurie, a measurement of radiation), how much 1311 will still be in her system when she can
safely become pregnant?
O 22.5 x 10-6 mc
O 3.125% of the original isotope

Both sound waves and light waves undergo the phenomenon of refraction when they travel form air to water. How is refraction of sound waves different from the refraction of light waves?
Answer:
Glass is denser than air, so a light ray passing from air into glass slows down. If the ray meets the boundary at an angle to the normal , it bends towards the normal. The reverse is also true. A light ray speeds up as it passes from glass into air, and bends away from the normal by the same angle.

Oo
Explanation:
The true statement about gravity is that it is the force of attraction between two objects with masses and also, based on the distance between these objects.
Gravity is a force of attraction.
The best scientific overview of the force of gravity is given by the Newton's law of universal gravitation which states that "the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them",
So, gravitational force of attraction is dependent on mass and the distance between two bodies.
What are the paper sleeves that were invented in 1991 called for coffee cups
Answer:
Sorensen invented the insulated sleeve to fit around a standard paper coffee cup saving millions of coffee drinkers from burns. The sleeve was called the Java Jacket for which he obtained patent protection. Java Jacket, Inc. was incorporated in 1993 by Inventor Sorensen with an investment of just $20,000.Oct 8, 2013

Answer:
Housed in the same building as Vincent van Gogh’s “The Starry Night” and Andy Warhol’s “Campbell’s Soup Cans” is a simple paper coffee cup sleeve. It can be found not in the café at New York’s Museum of Modern Art (MoMA), but rather in the museum’s collections alongside renowned works of art worth millions. But it would be wrong to consider it out of place; the genius of the coffee cup sleeves makes it a million-dollar object as well.
For many, the morning ritual wouldn’t be complete without standing in line at a nearby coffee shop, placing an order with a frazzled cashier managing the A.M. rush and watching the barista pour the coffee, slap a slid on top of the cup and slip a cardboard sleeve over it. It’s a simple and logical ritual, but without that sleeve, what would have happened to our to-go coffee culture? In 2005, MoMA paid tribute to this ingenious design defining the modern American coffee tradition when it acquired a standard coffee cup sleeve for the exhibit “SAFE: Design Takes on Risk,” which featured products that were created to protect. The sleeve takes pride of place at MoMA, alongside Post-It notes, Bic pens and Band-Aids in a collection called “Humble Masterpieces.”

Explain what was ultimately responsible for London’s “killer fog” in 1952.
Answer:
possible answer from edge
Explanation:
After World War II the only coal available to burn residentially, either for cooking or warmth, was of poor quality and contained large amounts of contaminants that made its fumes toxic. So when millions of homes in London burned this low quality coal and the local atmosphere over and around London stagnated, there was nowhere for the fumes to go. This stagnation allowed the toxic coal fumes to build up until they became physically harmful to humans and animals.
Burning of low quality coal was ultimately responsible for London’s “killer fog” in 1952.
What is Coal?This is a type of sedimentary rock which is combustible and contain high amounts of carbon and hydrocarbon.
The low quality coal contained a lot of contaminants which was released into the atmosphere thereby creating the “killer fog” which adversely affected residents.

Calculate how long it would take a car traveling at 30m/s to come to a complete stop if it has a constant deceleration of 4m/s²
Answer:
7.5s
Explanation:
Given parameters:
Velocity = 30m/s
Deceleration = 4m/s²
Unknown:
Time it takes for the car to come to complete rest = ?
Solution:
To solve this problem, we use the kinematics expression below:
v = u + at
Since this is a deceleration
v = u - at
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken
v - u = -at
0 - 30 = -4 x t
-30 = -4t
t = 7.5s

Based on the degree of refraction from least to most refracted, the colors are as follows: Red, Orange, Yellow, Green, Blue, Indigo, Violet.
What is refraction of light?Refraction of light is the bending of light rays as they cross the boundary between two media of different densities.
White light consists of seven colors of light; Red, Orange, Yellow, Green, Blue, Indigo, Violet.
The red color has the shortest wavelength and is the least refracted while violet color has the longest wavelength and is most refracted.
Therefore, based on the degree of refraction from least to most refracted, the colors are as follows: Red, Orange, Yellow, Green, Blue, Indigo, Violet.

Dr. Suarez walks 2.8 km north to get to an observation post, then walks 5.1 km south back to her outpost. Determine her distance.
A.) 2.3 km, north
B.) 7.9 km, south
C.) 7.9 km
D.) 2.3 km
Answer:
C.) 7.9 km
Explanation:
Distance and Displacement
An object who constantly travels for some distances at defined periods of time has a total distance as the sum of each individual distance the object traveled. It can be written as:
dtotal=d1+d2+d3+...+dn
This sum is obtained independently of the direction the object moves.
The displacement only takes into consideration the initial and final points of the path defined by the object in its moving. The displacement, unlike distance, is a vectorial magnitude and can be even zero if the object starts and ends the movement at the same point.
Dr. Suarez walks 2.8 km north and then 5.1 km south. The total distance is simply the sum of both distances: 2.8 km + 5.1 km = 7.9 km.
Note the distance does not have any direction (north or south), it's just the number.
Answer: C.) 7.9 km
