Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +...
Answer:
resistance = 0.9230769230769231
Explanation:
The total resistance can be found by using the following equation:
1 / R = 1 / R1 + 1 / R2 + 1 / R3

Explanation:
why is a neutral solution neutral?
Answer:
A neutral solution is neutral if it has the same concentration of hydrogen ions as the hydroxide ions.
Explanation:
Hydrogen ions have a positive charge [H+] while Hydroxide ions have a negative charge [OH-]. Given that a solution has equal amounts of both Hydrogen and Hydroxide ions, the charges cancel each other out resulting in a neutral solution.
Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas
A:Some of the chemical energy in the natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and the steam leaves the kettle.
B:Some of the electrical energy in the natural gas transforms into thermal energy, which causes the water to form steam. Then some of the thermal energy changes into sound energy and light energy when the steam leaves the kettle.

Use the Sentence Starter to help you:
Matter and energy move through an ecosystem by...
Answer:
Decomposers (organisms that break down dead producers and consumers and organic waste) obtain the energy they need to live from chemical bonds of the dead and waste-matter. The energy is transferred both to the decomposer (for growth and development) and to the ecosystem (as heat energy)

A book is sliding across a horizontal tabletop. As it slides, slows down. Which of the following statements best explains this situation?
There is a balanced force on the book caused by gravity.
There is no upward force acting on the book.
There is an unbalanced force on the book caused by friction.
There are no unbalanced forces acting on the book.
A book is sliding across a horizontal tabletop. As it slides, slows down. There is an unbalanced force on the book caused by friction.
What is friction ?The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are several kinds of friction, The force that opposes the relative lateral motion of two solid surfaces in contact is known as dry friction.
When a stick is used to beat the carpet, a little amount of static friction occurs, holding the dust to the carpet. When we beat a carpet with a stick, the stick's external force forces the carpet to move away from the dust by overcoming friction.
A frictional force or an opposing force is produced when two rough surfaces come into contact with one another. This force can occasionally be transformed into heat.
Thus, option C is correct.

Explain why action and reaction forces are not balanced forces.
Answer:
Explanation:
Newton's third law of motion states that every action has an equal and opposite reaction. This means that forces always act in pairs. Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don't cancel out. hope that helped
Answer:
Action and reaction forces are equal and opposite, but they are not balanced forces because they act on different objects so they don’t cancel out.
