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 = […]
What is the 2nd harmonic also referred to?
What is the 2nd harmonic also referred to? Second Harmonic Such positions are referred to as nodal positions or nodes. The lowest possible frequency at which a string could vibrate to form a standing wave pattern is known as the fundamental frequency or the first harmonic. Which generators have the lowest THD rating? The A-iPower […]
How do you know if an image is real or virtual?
What would happen to pressure in the tire if some of the air were removed?
What would happen to pressure in the tire if some of the air were removed? The pressure inside the tire will keep on decreasing as more air leaks out of the tire because the number of air particles inside the tire decreases resulting in less collisions than before and due to the less frequent collisions […]
What are three non-sampling errors?
What are three non-sampling errors? Non-sampling errors include non-response errors, coverage errors, interview errors, and processing errors. A coverage error would occur, for example, if a person were counted twice in a survey, or their answers were duplicated on the survey. What are examples of non-sampling errors? Any error or inaccuracies caused by factors other […]
Which are characteristics of a ray when it hits a boundary and refracts but not?
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 […]
How do you calculate area with pressure and force?
How do you calculate area with pressure and force? Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. How is area related […]
Does masturbation affect immunity?
Does masturbation affect immunity? An orgasm may benefit your immune system Though the study was very small, the researchers found that masturbation increased the number of inflammatory mediators called leukocytes (white blood cells) and natural killer cells. Both of these fight infection as a part of the body’s immune response. How can you tell if […]
What is the point of neutrons?
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 […]
