What happens to the surface of the water when the rate of evaporation is greater? A substance that has a larger surface area will evaporate faster, as there are more surface molecules per unit of volume that are potentially able to escape. the higher the temperature of the substance the greater the kinetic energy of […]
What should you not do feedback?
What should you not do feedback? Here are some simple do’s and don’ts to remember when giving feedback. Do’s. Do make sure to be specific. Do give the recipient a chance to respond. Do consider the recipient’s needs. Do only give negative feedback in private. Don’ts. Don’t wait. Don’t sandwich negative feedback between positive messages. […]
At which points does destructive interference occur?
At which points does destructive interference occur? Destructive interference occurs when the maxima of two waves are 180 degrees out of phase: a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave. The amplitude of the resulting wave is zero. What are the two main kinds of interference? […]
Will heating a bolt loosen it?
Will heating a bolt loosen it? Applying heat with a propane torch can expand a nut (or threaded opening) and loosen it. If you’ve tried everything and still can’t free a bolt or nut, try heat. Once you’ve established that it’s safe, aim the flame at the bolt head or nut, not the surrounding metal. […]
Why do magnetic stripes on the ocean floor form a symmetrical pattern on either side of mid ocean ridges?
Why do magnetic stripes on the ocean floor form a symmetrical pattern on either side of mid ocean ridges? When lava gets erupted at the mid-ocean ridge axis it cools and turns into hard rock. As it cools it becomes permanently magnetized in the direction of the Earth’s magnetic field. This creates a symmetrical pattern […]
Why is AAA not a congruence test?
Why is AAA not a congruence test? Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. When you’re trying to determine if two triangles are congruent, there are 4 shortcuts that will work. Because there are 6 corresponding parts 3 angles and 3 sides, you don’t need to […]
Can you walk normal in space?
Can plants grow under normal light bulb?
Can plants grow under normal light bulb? People often assume you need expensive grow lights to make up for the lack of natural light, but they’re wrong. You can actually use regular light bulbs to grow plants indoors. Can you grow snake plants in water? Learning how to propagate snake plants is easy. It’s true […]
Why are carbon brushes used in AC generators?
Why are carbon brushes used in AC generators? A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part in a motor or generator, and, as regards DC machines, ensuring a spark-free commutation. Why brushes are used in motor? They can either be graphite or precious metal […]
