Measure length, width, and height and multiply. 4. How would you calculate the volume of an irregular sized object like a rock? […]
Why does a white shirt look blue?
When two or more systems are in thermal equilibrium with each other they will have the same temperature?
When two or more systems are in thermal equilibrium with each other they will have the same temperature? In other words, if two objects are in thermal equilibrium, they have the same temperature. If thermometer A is in thermal equilibrium with object B, and B is in thermal equilibrium with C, then A is in […]

What is true for electromagnetic waves?
What is true for electromagnetic waves? Definition: Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields. They are also perpendicular to the direction of the EM wave. How […]
Which property of water makes it more useful as a coolant in sweating?
Which property of water makes it more useful as a coolant in sweating? Water’s thermal properties, its high specific heat, means that it can cool us Evaporating sweat (water changing phase from liquid to gas) takes heat away from the body Water is also the main component of blood plasma. It transfers heat from the […]
What heart rate should I aim for when running?
What heart rate should I aim for when running? You can determine your target heart rate for running using a formula based on your age and maximum heart rate. When running, you should train at 50 to 85 percent of your maximum heart rate. To calculate the maximum rate, subtract your age from 220. What […]
Does amplitude equal loudness?
Does amplitude equal loudness? The amplitude of a sound wave determines its loudness or volume. A larger amplitude means a louder sound, and a smaller amplitude means a softer sound. The volume we receive thus depends on both the amplitude of a sound wave and whether its frequency lies in a region where the ear […]
