A yellow ball with a mass of 2 kg is rolling across the floor at 3 m/s. A red ball with a mass of 3 kg is rolling across the same floor at 3 m/s. Which ball has greater kinetic energy, and why?
plz hurry in the test nowwwwww!!!!!!
Answer:
In order to determine which ball has a higher kinetic energy, we first look at the formula of kinetic energy which is:
kinetic energy = 1/2 * mass * velocity²
The factors influencing the kinetic energy of an object are its mass and its velocity. Both of the balls have the same velocity; however, the red ball has a greater mass. Therefore,
The red ball has greater kinetic energy, because it has a greater mass.
We may also determine these quantitatively using the formula given and the kinetic energy of the yellow ball works out to be 9 J and that of the red ball is 13.5 J.
Explanation:
Potassium (K) is found in Group 1. Fluorine (F) is found in Group 17. When these atoms bind, which will form the positive ion, and which will form the negative ion? Why? Hint: Refer back to the periodic table.
Answer:
The oppositely charged ions form an electrostatic attraction, which is the ionic bond. The compound potassium fluoride (KF) results, and since the potassium and fluoride ions have equal but opposite charges, the compound is neutral (but not the individual ions in the compound).

A silver ring reacts with compounds containing sulfur in the air to form silver sulfide, a black substance that makes up the tarnish on the surface of silver objects. To remove that tarnish from the ring, students placed it in a pan lined with aluminum foil and added hot water. Baking soda was added to the hot water and stirred. Students made observations about the process. Which observation of this process provides evidence of a chemical reaction? *
A- Hot water heated the aluminum foil
B- The liquid solution changed color
C- The pan was lined with aluminum foil
D- The hot water cooled
Answer: B
Explaination: The liquid solution changed color means is turned into a different substance with different properties. It is chemical change .
Liquid solution changed color provides an evidence of a chemical reaction as it is accompanied by a chemical change.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

a large block of ice can heat up a small pool of liquid nitrogen. ice is 0 celcius but liquid nitrogen is -210 celsius. so the heat from the ice will warm up the nitrogen pool until they reach equilibrium. true or false?
how does oxygen get in the water choose all that apply
Answer:
Oxygen dissolves in surface water due to the aerating action of winds. Oxygen is also introduced into the water as a byproduct of aquatic plant photosynthesis. And When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive.

A toy truck falls off a table. As it falls, the toy truck has potential energy and kinetic energy.
Explain how the toy truck can have potential and kinetic energy at the same time.
As the toy falls off a table, it can have potential and kinetic energy at the same time because of the height (h) and velocity (v) of the object, respectively.
When the truck falls off a table it has potential energy (P) and kinetic energy (K) given by:
[tex] P = mgh [/tex] (1)
[tex] K = \frac{1}{2}mv^{2} [/tex] (2)
Where:
m: is the mass of the toy
g: is the acceleration due to gravity
h: is the height of the table
v: is the velocity of the toy
Kinetic energy (equation 2) is related to the velocity (v) of the moving toy while it is falling from the table.
Potential energy (equation 1) is due to the gravitational acceleration (g) exerted on the toy when it is at a height (h) above the table. This energy decreases as the object approaches the ground (where "h" is zero).
Therefore, the truck can have potential and kinetic energy at the same time because of the height and velocity of the toy, respectively.

-The students in Ms. Wilson’s science class were asked to create analogies to describe the function of organelles in a cell. Of the statements below, which one best represents the organelle and its function? a. Camille described the nucleus as a donut because it has a hole in the middle of it. b. Simon described the chloroplast as a water filter because it filters out the bad things from entering a cell. c. Ricardo described the vacuole as a security guard because it allows things into the cell.
d. Angie described the lysosome as a vacuum because its function is to clean the cell.
Answer:
D. Angie described the lysosome as a vacuum because its function is to clean the cell.
Explanation:
Because vacuumes clean and so do that part of the organelles
When does a short circuit occur?
Answer:
A short circuit is when there is a low resistance connection between two conductors that are supplying electrical power to a circuit. This would generate an excess of voltage streaming and cause excessive flow of current in the power source. The electricity will flow through a 'short' route and cause a short circuit.

Looking at the information given in the description, the experiment is testing for the effects of the different salts on the growth of the plants.
This means that the type of salt is the independent variable, or the variable being manipulated and tested.
To ensure fair results, some parts of the experiment would need to be kept the same, which is the control. The only answer choice that makes sense in this instance is A. water.
