When three different resistances R1 R2 and R3 are connected in parallel where R1 R2 R3 the equivalent resistance of the combination will be?
When three different resistances R1 R2 and R3 are connected in parallel where R1 R2 R3 the equivalent resistance of the combination will be? it is clear from the equation that value of R is less than R1 orR2 or R3=1 , therefore equivalent resistance of this combination is less than 1 ohm . When […]
How does the earth tilt affect you?
How does the earth tilt affect you? But Earth’s distance from the sun doesn’t change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun’s light and warmth most […]
What is the most accepted theory of how the Moon formed?
What is the most accepted theory of how the Moon formed? What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form […]
What muscles are targeted when doing sit and reach?
What muscles are targeted when doing sit and reach? The sit and reach test is a common measure of flexibility, and specifically measures the flexibility of the lower back and hamstring muscles. This test is important as because tightness in this area is implicated in lumbar lordosis, forward pelvic tilt and lower back pain. How […]
How does chlorine oxidize?
How does chlorine oxidize? Chlorine kills bacteria though a fairly simple chemical reaction. Both kill microorganisms and bacteria by attacking the lipids in the cell walls and destroying the enzymes and structures inside the cell, rendering them oxidized and harmless. The difference between HOCl and OCl- is the speed at which they oxidize. What are […]
Why is AC power used instead of DC?
Why is AC power used instead of DC? Since high voltages are more efficient for sending electricity great distances, AC electricity has an advantage over DC. This is because the high voltages from the power station can be easily reduced to a safer voltage for use in the house. Changing voltages is done by the […]
When would you request a contact approach?
When would you request a contact approach? A contact approach will only be issued if the aircraft is operating clear of clouds with at least 1-mile of flight visibility, with a reasonable expectation of continuing to the destination airport under those conditions. Which is true regarding the use of an instrument departure procedure? Which is […]
What is apparent brightness measured in?
What is apparent brightness measured in? watts per square meter Which best describes the relationship between brightness B and distance d )? Inverse Square Law of Brightness The Apparent Brightness (B) of a source is inversely proportional to the square of its distance (d): Implications: It will appear 22=4 times brighter. What is apparent magnitude […]
What is controlled falling?
What is controlled falling? Falling Means Letting Go He would have to look down to see if his foot had made contact with the ground. He (understandably) had trouble relaxing. Walking is controlled falling because you need to let go in order to move forward. If you never let your foot fall, your movements would […]
