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 […]
What products increase friction?
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 […]
Why does the speedometer of a car read instantaneous speed?
Why does the speedometer of a car read instantaneous speed? The speedometer of a car read the instantaneous speed not the average speed. We know that average speed is the ratio of total distance to the total time.It changes during when the car is moving . What does the speedometer of the car measure? Speedometer, […]
What best compares radiation and conduction?
What best compares radiation and conduction? The statements that best compares radiation and conduction are the following: both transfer thermal energy from warm objects to cooler objects and both can transfer energy through matter. The difference is that conduction is through direct heat transfer; whereas, radiation transfers heat through waves. What describes how radiation moves? […]
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 […]
How many circles do you need to balance the scale?
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 […]
How do environmental scientists use technology to track gray wolves?
How do environmental scientists use technology to track gray wolves? How do environmental scientists use technology to track gray wolves? A. They use gel electrophoresis to analyze wolf DNA. They use acoustics to identify wolves by their howls. What could we change about the way we use land to reduce deforestation? By consuming less, avoiding […]
What is the major source of energy for living organisms?
What is the major source of energy for living organisms? The Sun What is importance of classification? Three importance of classification are: It helps in the identification of living organisms as well as in understanding the diversity of living organisms. To understand and study the features, similarities and differences between different living organisms and how […]
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 […]
