Why do we need controls? Controls allow the experimenter to minimize the effects of factors other than the one being tested. It’s how we know an experiment is testing the thing it claims to be testing. This goes beyond science — controls are necessary for any sort of experimental testing, no matter the subject area. […]
What is responsible for holding a car in a curve?
What is responsible for holding a car in a curve? Answer and Explanation: The force responsible for holding a car in an unbanked curve is (c) the force of friction because this is the only force acting on the radial direction. The car’s weight, the reaction force to the car’s weight (normal force) only acts […]

Why is the strong force so strong?
Why is the strong force so strong? The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei. As such it is responsible for the underlying stability of matter. What is most powerful force in […]
What happens when frequency of a sound increases?
What happens when frequency of a sound increases? When you increase the frequency of a sound wave, the sound waves get compressed and we hear the sound at a faster rate. The pitch of the sound increases. What would happen if you increased the frequency of a sound? So if you increase the frequency, on […]
