Is it correct to say the impulse is equal to? Impulse is equal to the change in momentum. The correct option is B. Is it correct to say that if no net impulse is exerted on a system? No, never. Is it correct to say that, if no net impulse is exerted on a system, […]
Why does water get cold in clay jars?
What type of friction must you overcome to start an object moving?
What type of friction must you overcome to start an object moving? static friction Does kinetic friction speed up or slow down an object? Does friction always slow things down? ANSWER: No! Kinetic friction does oppose the relative motion of two surfaces. If the one of these surfaces is stationary, then it will tend to […]

What is the strongest element bond?
What is the strongest element bond? Covalent bond Is carbon tetrafluoride a hydrogen bond? Is ch2o a hydrogen bond? No Hydrogen bonding in CH2O because hydrogen bonding means it has to be attached more electronegative atoms like Oxygen or Fluorine but in the case of CH2O, hydrogen is attached with carbon atom so conclusion is […]
Why is exit wound bigger than entry?
Why is exit wound bigger than entry? Exit wounds – as we have already mentioned – are usually larger than the entrance wound and this is because as the round moves through the body of the victim it slows down and explodes within the tissue and surrounding muscle. How can firearms and bullets be used […]
What is a price demand function?
What is a price demand function? Price-Demand (p): is usually given as some P(x) = –ax + b. However, sometimes you have to create P(x) from price information. • P(x) can be calculated using point slope equation given: Price is $14 for 200 units sold. Which is the demand function? Demand function shows the functional […]
What is capacitance and dielectrics?
What is capacitance and dielectrics? capacitance: amount of charge stored per unit volt. dielectric: an insulating material. dielectric strength: the maximum electric field above which an insulating material begins to break down and conduct. What is resistance and capacitance? Resistance is the measure of the amount of energy dissipated by the resistor. While capacitance is […]
What is kVp vs mAs?
What is kVp vs mAs? * kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts. Understanding Technique. kVp stands for kilovoltage peak. What is source […]
