5 of the biggest unsolved mysteries in physics The mysteries of the universe are as vast and wide as existence itself. Throughout history‚ mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker’s Guide to the Galaxy‚ "I think the problem‚ to be quite honest with you‚ is that you’ve never actually known what the question is." True‚ we have yet to come up with the answers to life‚ the universe

Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

ARCELIA ARRATIA MEASUREMENT OF LENGTH‚ MASS‚ VOLUME‚ AND DENSITY PHYSICS LAB REPORT Physics is the scientific study of matter and energy and how they interact with each other. Physics utilizes the scientific formula to test hypothesis and calculate matter such as density. Tools were created to measure material in a laboratory and have been perfected to reduce error. In this experiment measurement of length‚ mass‚ volume and density will be obtained through instruments of measuring

Physics Preliminary 8.2 The World Communicates 1. The wave model can be used to explain how current technologies transfer information 1. Describe the energy transformations required in one of the following: – Mobile telephone – Fax/modem – Radio and television A. An energy transformation is a change in the type of energy‚ for example a change from sound energy to electromagnetic waves. Relating this to the mobile telephone‚ it undergoes basic energy transformations of‚ sound wave

Prediction I think that the speed of the cart will decrease as more weight is added on top of the cart. This is because the more weight that is placed on the moving vehicle/object‚ the more downward force is produced. This would increase the friction between the wheels of the cart and the ramp’s surface. The increase in friction would slow down the moving object (cart). Apparatus Trolley/cart- this is essentially a wooden block with wheels and a rubber end‚ to provide the collision with a
