When does a short circuit occur?
Answers
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.
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.
Answers
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 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!!!!!!
Answers
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.

Answer:
Kudzu kills trees and other plants by smothering and choking them with its fast-growing vines, and as the heavy vines engulf trees or shrubs their weight can actually break or uproot trees. A kudzu vine can grow as much as a foot per day and sixty feet during a growing season.
Explanation:
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
Answers
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.

What other property of water that relies on adhesion?
HINT: It involves defying gravity.
Answers
Answer:
Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules
Explanation:
*Explanation* Adhesion of water
Water likes to stick to itself, but under certain circumstances, it actually prefers to stick to other types of molecules. Adhesion is the attraction of molecules of one kind for molecules of a different kind, and it can be quite strong for water, especially with other molecules bearing positive or negative charges.
For instance, adhesion enables water to “climb” upwards through thin glass tubes (called capillary tubes) placed in a beaker of water. This upward motion against gravity, known as capillary action, depends on the attraction between water molecules and the glass walls of the tube (adhesion), as well as on interactions between water molecules (cohesion).

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.
Answers
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.
