What products increase friction? There are two methods of increasing friction: one is by making the surfaces rough and the other by increasing the mass of the object that is moving. For example, the tyres of vehicles have treads (these are the ‘designs’ that you can see on the tyre surface), which increase the friction […]
What is the dimension of radiation intensity?
What is the dimension of radiation intensity? Hence, the unit of intensity will be kgm2s−2m2s=kgm0s−3. Mass has the unit of kg, length has the unit of m and time has the unit of s. Therefore, the dimensional formula of intensity is [ML0T−3]. What is the dimension of radiation? In this work it is shown that […]

Can you drive without airbags?
Can you drive without airbags? It’s not illegal to drive without airbags, if your vehicle was manufactured before 1989. So the question then arises: What happens if you have no airbags and get into a crash? Airbags help slow down the change in momentum and help reduce the forces in a crash. How unsafe is […]

What are the 3 right hand rules?
What are the 3 right hand rules? These are for (1) long, straight wires, (2) free moving charges in magnetic fields, and (3) the solenoid rule – which are loops of current. Calling these “rules” is the right name. What is the application of right hand thumb rule? The right-hand thumb rules can be used […]

How can you tell if two rectangles are similar?
How can you tell if two rectangles are similar? For two rectangles to be similar, their sides have to be proportional (form equal ratios). The ratio of the two longer sides should equal the ratio of the two shorter sides. How do you know if two parallelograms are similar? Find a pair of possible adjacent […]
What is the proton symbol?
What is the proton symbol? p+ How are nucleons kept together? The strong nuclear force. At extremely short range, it is stronger than electrostatic repulsion, and allows protons to stick together in a nucleus even though their charges repel each other. Remember that the size of the nucleus is really small compared to the size […]
