Does electricity flow through the wire around the core? An electromagnet is made by sending electric current through an insulated wire wrapped around the iron core. How does the number of winds or wire around a core affect the strength of the magnetism? Electricity gets in more, because the more winds equals more magnetism. Which […]
What is total internal reflection simple definition?
What is total internal reflection simple definition? Total internal reflection, in physics, complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle. What […]
What is the impact of food chain in our daily life?
What is the impact of food chain in our daily life? Food chains are important because they show the intricate relationships in ecosystems. They can reveal how each organism depends on someone else for survival. Food chains also display what happens when a problem occurs and a producer or consumer is lost. Entire communities can […]
Why is Ocean important for food?
Is the angle of incidence is 30 What is the value of the angle of reflection?
How do you force acceleration times?
How do you force acceleration times? Newton’s second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration. Created by Sal Khan. What are the 3 forms of acceleration? In physics, the three types of acceleration are changes in speed, direction […]
What did Harry Harlow find when he gave monkeys raised in isolation the choice of cloth covered or wire substitute mothers?
What did Harry Harlow find when he gave monkeys raised in isolation the choice of cloth covered or wire substitute mothers? In both conditions, Harlow found that the infant monkeys spent significantly more time with the terry cloth mother than they did with the wire mother. When only the wire mother had food, the babies […]
Are tube radios dangerous?
Are tube radios dangerous? AFAIK, these are all voltage regulator tubes and have the standard radiation symbol printed on them (unless it has worn off). 3) CRTs. These are dangerous because of their size and that they contain a vacuum. They can implode (not explode) violently if broken. Are old tube radios safe? An antique […]
What is the true bond angle of H2O?
What is the true bond angle of H2O? In lecture, Lavelle had mentioned that the bond angle for H2O is (104.5) less than 109.5. What is the bond angle between the oxygen atoms in the carbon dioxide molecule? 180 degrees What shape is SiS2? A.P. Chem Chapter 10 and 11 (Bonding) Review Concentration A B […]
