Q.1. What kind of waves are present during an earthquake?
Ans . There are four main types of earthquake waves: P-waves and S-waves (which are body waves), and Rayleigh waves and Love waves (which are surface waves).
Q.2 What kind of energy does an unlit match have? ...
Ans . potential energy
Q3. Which of these is another way to write Newton's second law of motion?
Ans . In equation form, Newton's second law of motion is a=Fnetm a = F net m .
Q.4 What is it called when light changes direction after leaving a lens? ...
Ans. Light doesn’t change direction after leaving a lens in a camera. it does change direction in the lens and this is called refraction i believe. of course reflection is also light changing direction and this happens to light in a slr while one is looking through the viewfinder before the mirror flips up to take the picture.
Q.5 How do you calculate density?
Ans . To find the density of any object, you need to know the Mass (grams) of the object, and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get an object's Density.
