Can something have more than one type of energy? Energy comes in many different types, which can be categorised into two basic forms – kinetic and potential. Energy can never be created or destroyed, but it can be transformed from one type of energy to another. What happens if you drop the skater onto the […]
What do you know about a substance it you know its temperature?
What do you know about a substance it you know its temperature? In chemistry, we define the temperature of a substance as the average kinetic energy of all the atoms or molecules of that substance. Not all of the particles of a substance have the same kinetic energy. At any given time, the kinetic energy […]
Does speed of sound depend on humidity?
Does speed of sound depend on humidity? The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. Dry air absorbs far more acoustical energy than does moist air. This is because moist air is less dense than dry […]
What is the chemical symbol of atom?
What is the chemical symbol of atom? List of chemical symbols Chemical symbol Name of Element Atomic No Ni Nickel 28 No Nobelium 102 Np Neptunium 93 O Oxygen 8 What are the smallest particles of an element? An atom is the smallest particle of an element that still has the properties of that element. […]
What does it mean if two objects have the same mass?
Do heavier objects fall faster?
Do heavier objects fall faster? Galileo discovered that objects that are more dense, or have more mass, fall at a faster rate than less dense objects, due to this air resistance. How do you find velocity with time and height? An object is thrown straight up from the top of a building h feet tall […]
Can you be in a relationship and still be single?
What is the difference between real and virtual image?
What is the difference between real and virtual image? The main difference between real and virtual images lies in the way in which they are produced. A real image is formed when rays converge, whereas a virtual image occurs where rays only appear to diverge. Can real image be seen without a screen? Well actually […]
What is the purpose of drawing in one point perspective?
What is the purpose of drawing in one point perspective? One point perspective is a drawing method that shows how things appear to get smaller as they get further away, converging towards a single ‘vanishing point’ on the horizon line. It is a way of drawing objects upon a flat piece of paper (or other […]
What is beef stock made of?
What is beef stock made of? What Is Stock? Stock is made by simmering a combination of animal bones (which typically contain some scraps of meat), mirepoix (a mixture of onions, carrots, and celery), and aromatics in water. Stock always involves bones, although not necessarily meat. What are the main ingredients in stock? Stocks contain […]
