Class XI Exercise 4 – Motion in a Plane Physics Question 4.1: State‚ for each of the following physical quantities‚ if it is a scalar or a vector: volume‚ mass‚ speed‚ acceleration‚ density‚ number of moles‚ velocity‚ angular frequency‚ displacement‚ angular velocity. Answer: Scalar: Volume‚ mass‚ speed‚ density‚ number of moles‚ angular frequency Vector: Acceleration‚ velocity‚ displacement‚ angular velocity A scalar quantity is specified by its magnitude only. It does not have any

The Nobel Prize in Physics 1968 was awarded to Luis Alvarez "for his decisive contributions to elementary particle physics‚ in particular the discovery of a large number of resonance states‚ made possible through his development of the technique of using hydrogen bubble chamber and data analysis". Alvarez’s colleagues sometimes called him the "prize wild idea man" because of the huge range of his activities. He did all kinds of research into the atomic nucleus‚ light‚ electrons‚ radar‚ and so

factors can play into an accident. Road condition‚ mechanical failure‚ driver error‚ or simply an ’act of God’? Despite the countless reasons for a car accident‚ one factor is always present‚ no matter what the case: physics. Every accident that has ever occurred has involved physics. Using references found in the class text‚ in science journals‚ and on the Internet‚ I will prove this to you. Take‚ for example‚ two cars traveling in opposite directions at 100km/h. One of the drivers dozes off and

Aim: To find the mass in grams (m) of a paperclip. Apparatus: Procedure: 1. Using a piece of string‚ the external circumference(C) of the small test tube was found and was then used to find A ‚ the cross sectional area of the small test tube A=C24π . 2. The beaker was placed under the test tube after it was clamped on the retort stand to collect excess water. The large test tube was filled with water. After which‚ the small test tube which had a fitted scale was placed inside to float

The Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would

Chapter 19 Nuclear Energy 19.1 Energy in your life Almost everything around us uses electricity and in order to power these devices‚ we must generate it. To create electrical energy‚ we must create thermal energy. Several techniques include using coal‚ natural gas‚ or nuclear thermal to create heat. Once heat is created‚ it is used to vaporize water and use the steam to propel a piston which turns an electric generator. Alternative energy sources include wind‚ solar‚ and micro hydro. 19.2 Nuclear

Height of Ball Drop v/s The Depth of the Crater | By Tejas Shah‚ IBDP Year 1 | | | | | | | * Aim- To find the relationship between the depth of crater and the height from which it is dropped. * Research Question- Does the height from where the ball is released affect the depth of the crater. * Hypothesis- If we increase the height of the drop of the ball; the depth of the crater would increase. This is because as there is loss in potential energy subsequently there

HIGH-VELOCITY INJURIES Harland Hayes‚ University of Utah School of Medicine It should be no great surprise to find out that the most serious of injuries that occur in the back country are those that are associated when people are moving with speed. There are common sports that by their very nature require speed such as skiing where injuries don’t have to occur. However‚ there are other sports that demand deliberate even delicate moves‚ such as rock climbing‚ where speed gained from a fall
