An electrical circuit can be defined as something which helps electrons to flow in a continuous uniform direction through wires. This flow of electrons occurs in a never ending loop without any source or destination. This cannot happen in a broken circuit. This loop should be made up of some conductive material.
FIVE THINGS
Ampere is the unit of measuring electric current.
Electric circuits are used to power bulbs or other electric components.
A battery is the major components of an electric circuit which acts as a power source. It provides energy which helps electrons to flow.
A battery consists of one or more section or cells. In every section, two electrodes are separated by a liquid or paste which is called electrolyte. Number of cells depends on the size of battery.
The amount of flowing electric charge in one second is called current.
In a circuit, electrons flow from negative to positive.
All the required components for formation of a circuit are: – battery, wires, bulbs, switches and motors.
A switch is used to control the flow of electricity. If a switch is open, it will create a gap in the circuit and current will not flow. When it is closed, circuit will be completed and flow of current will be continued.
Answer and Explanation:
1. To facilitate the examination and communication with Sara, it would be important to politely ask her mother to leave the room. This could make Sara more relaxed and allow her to feel more comfortable answering questions, as we can see that her mother's presence is bothering her. Then it would be important to tell Sara that everything that was said in the room would be confidential and no one besides her and the interviewer would know about anything she said, for this reason, she could speak without fear of suffering any reprisal or having the content of the conversation disseminated.
2. Sara may be facing issues related to her teenage insecurities. She is 14 years old and it is common for teenagers at this age to become irritable, moody and anxious. She may also be facing problems related to substance ingestion, hormonal imbalance, among others.
3. To resolve concerns about Sara, it is important that the interviewer establish a relationship of complicity, so that Sara can inform what she is feeling, what is causing this behavior and what kind of situations she is involved. It is also important that she undergo medical tests that show the hormonal level and substances present in her body.

Explanation:
This would likely mean that the CPR is not being done correctly, and the other rescuer and you should remember to go at a steady pace.
Answer:
a. some of the calories contained in the rabbit are converted to free energy and some of the calories are converted to heat.
Explanation:
Energy can be defined as the ability (capacity) to do work.
Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.
This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.
Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.
When a wolf eats a rabbit, some of the calories contained in the rabbit are converted to free energy and some of the calories are converted to heat.
