Is work done when you lift an object? The force you are exerting is equal in magnitude and opposite in direction to the force of gravity. As you are lifting the object you are doing work on the object. The work W done on an object by a constant force is defined as W = […]

Is Q A joule or kilojoule? You want your q to be in units of Joules or kJ. If you used the q=mC(delta T) with your given C, your q would be in units of (grams)(kJ). In the problem, you were given the heat capacity, not the specific heat capacity. Therefore, you don’t need mass […]

What is an example of Kinesthesia? Through your sense of kinesthesis, you can tell where different parts of your body are located even if your eyes are closed or you are standing in a dark room. For example, when you are riding a bicycle, receptors in your arms and legs send information to the brain […]

Does a real diamond sparkle blue? A fake diamond will have rainbow colors that you can see inside the diamond. “People have a misconception that diamonds sparkle like a rainbow, but they don’t,” Hirsch said. “They do sparkle, but it’s more of a gray color. What color do real diamonds shine? The way that diamonds […]

What are the advantages and disadvantages of Mendeleev classification? When noble gases were discovered can be kept in a separate group without disturbing the existing order. Disadvantages: He couldn’t allocate a correct position to hydrogen. Atomic masses didn’t increase in a regular manner, so it was impossible to predict how many elements could be discovered […]

Which are characteristics of a ray when it hits a boundary and refracts but not? F. Only these two options are characteristics of a ray when it is refracted, but not when it is reflected. In fact: Reflection occurs when a ray hits the interface between two mediums and bounces off back. When it is […]

What is the DC voltage symbol? Direct Current Voltage (DCV): Sometimes it will be denoted with a V– instead. This setting is used to measure direct current (DC) voltage in things like batteries. Alternating Current Voltage (ACV): Sometimes it will be denoted with a V~ instead. How do I measure DC voltage without a multimeter? […]

What is the point of neutrons? Neutrons bind with protons and one another in the nucleus via the nuclear force, effectively moderating the repulsive forces between the protons and stabilizing the nucleus. How quickly does a neutron bomb kill? two days Is there a doomsday bomb? In a 2-part episode of the TV show The […]

What are different types of polarization? Following are the three types of polarization depending on the transverse and longitudinal wave motion: Linear polarization. Circular polarization. Elliptical polarization. What are the 4 types of polarization? polarization Electronic polarization. Ionic polarization. Orientational polarization. Space charge polarization. What is meant by dielectric Polarisation? Dielectric polarization is the term […]

Can 2 remote control cars same frequency? If you don’t plan to run your RC cars, trucks, boats, or aircraft alongside other radio controlled vehicles, it doesn’t really matter which frequency they use. However, running two 27MHz or two 49MHz RC cars near each other will usually result in interference—crosstalk. The radio signals get mixed […]
