Is a piece of information that is used to support a main idea? Evidence. Evidence is any piece of information used to support an idea or argument. Although evidence is not necessarily based in quantifiable fact, it is used to reinforce the idea of an argument, topic sentence, or main idea. When you look for […]
Why do they say feels like temperature?
Why do they say feels like temperature? The “feels like” temperature is a measurement of how hot or cold it really feels like outside. For example, skin that is exposed to wind and cold temperatures will make a person feel that it is colder outside than it really is because heat is drawn away from […]
How do you know if a gas is produced in a chemical reaction?
What happens if you triple the distance between two objects?
What happens if you triple the distance between two objects? If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power). What is the formula of gravitational force? The mathematical formula […]
What is the change in internal energy of the system when no heat is absorbed by the system from the surroundings but work is done by the system what type of wall does the system have?
What is the change in internal energy of the system when no heat is absorbed by the system from the surroundings but work is done by the system what type of wall does the system have? adiabatic What is thermally conducting walls? Consider two systems A and B which are separated by a conducting wall. […]
What are the different types of reflections?
What are the different types of reflections? Types of reflection Reflection-in-action and Reflection-on-action. Two main types of reflection are often referred to – reflection-in-action and reflection-on-action. Reflection-in-action. This is the reflection that takes place whilst you are involved in the situation, often a patient interaction. Reflection-on-action. How do you write a good personal reflection? How […]
Does energy have momentum?
Does energy have momentum? Light indeed carries energy via its momentum despite having no mass. Public Domain Image, source: Christopher S. Baird. In the above equation, E is the total energy of the particle, p is the momentum of the particle (which is related to its motion), c is the speed of light, and m […]
Can atoms be broken down into smaller pieces?
Can atoms be broken down into smaller pieces? Under normal circumstances an atom can be broken down into any smaller particles, but we humans, have devised ways to break the atom apart. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. How many atoms are […]
Are combustion engines more efficient?
Are combustion engines more efficient? How efficient are engines? Combustion engines are stupefyingly inefficient. Most diesel engines do not even have a thermal efficiency of 50%. Of every gallon of diesel burned by a combustion engine, less than half of the energy generated becomes mechanical energy. How long will internal combustion engines be around? The […]
