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 is the most common ion of sodium?
What is the most common ion of sodium? The most important and familiar sodium compound is sodium chloride, or common salt, NaCl. Most other sodium compounds are prepared either directly or indirectly from sodium chloride, which occurs in seawater, in natural brines, and as rock salt. What happens to a sodium atom when it becomes […]
What are the developmental domains represented in the micro teaching objectives Infant Toddler foundations?
What are the developmental domains represented in the micro teaching objectives Infant Toddler foundations? Learning and Development Foundations provides an overview of development and a description of key competencies, or “Foundations,” for the following developmental domains: social-emotional development, language development, cognitive development, and perceptual and motor development. Which of these are domains in the Infant […]
Why protein is not a genetic material?
Why protein is not a genetic material? For a material to be genetic material, it has to replicate, it must be stable both structurally and chemically stable. Furthermore, it must be able to provide a scope for mutations eventually, key for evolution. Where are proteins made? Ribosomes Are proteins made in cytoplasm? Proteins all begin […]
What happens to the energy when you place a liquid in the freezer?
What happens to the energy when you place a liquid in the freezer? When water freezes it gives up some of the water’s energy. This energy that is given up is the latent heat of freezing. When the water was freezing latent heat of freezing energy was being released. Energy is being transferred even through […]
How do you test an overloaded circuit?
How do you test an overloaded circuit? How to Check for an Electrical Circuit Overload Turn off all appliances and wall switches and unplug all lamps and appliances plugged into the circuit. Locate the circuit panel, often found in the basement or garage of most homes. Power on the wall switches one at a time […]
What is the SI unit of time?
What is the SI unit of time? second. The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, […]
