What is the effective resistance between A and D? D=5Ω+10Ω+5Ω=20Ω What is the effective resistance in the given circuit? The effective resistance of a circuit containing resistances in parallel is smaller than any of the individual resistances. For example : R1=2Ω and R2=3Ω ∴ Effective resistance Rp1=R11+R21. Maximum effective resistance will be when all the […]
Do microwaves have radiation?
Do microwaves have radiation? Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays. But the most common consumer use of microwave energy is in microwave ovens. What […]
Why am I burning through coils so fast?
How can I get points off my license in Florida?
How can I get points off my license in Florida? The fastest and easiest way to reduce points is to take an online Basic Driver Improvement course. In Florida, you have the option to take this course once in a 12-month period, but no more than 5 times during your lifetime. All courses, whether in […]
What is the direction of acceleration of a particle in a uniform circular motion?
What is the direction of acceleration of a particle in a uniform circular motion? An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards. The animation at the right depicts this by means of a vector […]
What is the half-life of AU 198?
What is the half-life of AU 198? 2.697 days How do you calculate the half-life of sodium 24? Notice that the time period between each of the yellow crosses is 15 hours. This tells us that the count rate of Sodium-24 halves every 15 hours. In other words, the activity of Sodium-24 is halved every […]
What happens when Aluminium is burnt in the presence of oxygen?
What happens when Aluminium is burnt in the presence of oxygen? Reaction of aluminium with air So, normally, aulumium metal does not react with air. If the oxide layer is damaged, the aluminium metal is exposed to attack. Aluminium will burn in oxygen with a brilliant white flame to form the trioxide alumnium(III) oxide, Al2O3. […]
What is a good water quality index?
What is a good water quality index? The index ranges from 1 to 100; a higher number indicates better water quality. The WQI graphs show lavender for low concern, light yellow for moderate concern, and red for high concern or poor water quality. What is Bangladesh standard for drinking water quality? Advocate for a review […]
What is the direction of magnetic field at a point?
What is the direction of magnetic field at a point? Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north […]
