What is the normal to a line? The normal line to a curve at a particular point is the line through that point and perpendicular to the tangent. A person might remember from analytic geometry that the slope of any line perpendicular to a line with slope m is the negative reciprocal −1/m. How do […]
What is the direction of a friction force?
What is the direction of a friction force? The frictional force is the other component; it is in a direction parallel to the plane of the interface between objects. Friction always acts to oppose any relative motion between surfaces. Do we walk due to friction? When you are walking, static friction pushes in the direction […]
Why is the Ph of ethanol 7?
Why is the Ph of ethanol 7? Ethanol’s hydroxyl group causes the molecule to be slightly basic. It is almost neutral like water. The pH of 100% ethanol is 7.33, compared to 7.00 for pure water. This reaction is not possible in an aqueous solution, as water is more acidic, so that hydroxide is preferred […]
How do you know what type of function it is?
How do you know what type of function it is? One method for identifying functions is to look at the difference or the ratio of different values of the dependent variable. For example, if the difference between values of the dependent variable is the same each time we change the independent variable by the same […]
Will clogged ear go away by itself?
Will clogged ear go away by itself? A clogged ear is usually temporary, with many people successfully self-treating with home remedies and OTC medications. Contact your doctor if your ears remain blocked after experimenting with different home remedies, especially if you have hearing loss, ringing in the ears, or pain. How long does a blocked […]
Can you refuse to have your bags searched?
What should be used to put out electrical fire sand?
What should be used to put out electrical fire sand? In the case of electrical fires, also known as energized electrical fires, a class C fire extinguisher is needed to put it out. Can you melt dry ice with fire? Fire needs oxygen to burn, in the presence of carbon dioxide, the flame will extinguish. […]
What is the fastest unit of time?
What is the fastest unit of time? This apparent limit on time interval is about 10-43 second and is called Planck time. The Planck distance–how far light travels in one unit of Planck time–is about 10-35 meters, or about 1020 times smaller than the size of the nucleus of an atom. What is the shortest […]
What are the three equations of uniformly accelerated motion?
What are the three equations of uniformly accelerated motion? s=ut+12at2. C. v2=u2+2as. Hint: All the three equations for the uniformly accelerated motion can be derived by using the expressions for velocity, displacement, and acceleration and integrating them. What is the uniform accelerated motion? In general, a uniformly accelerated motion is the one in which the […]
