How do you solve Vo? To find the voltage at Vo, start at either end and add or subtract the voltage drop across the resistor. If we start at the 10V end: Vo = 10 – 3.58 = 6.42 V. If we start at the -2V end: Vo = -2 + 8.42 = 6.42 V. […]

What is the direction of the induced current in the circular loop of radius r?
What is the direction of the induced current in the circular loop of radius r? The direction of induced current in the circular loop will be clockwise or anti-clockwise depending upon the direction of current in the straight wire. The amount of induced current will be decided by the velocity with which the loop is […]
Is 1500 watts a lot of electricity?
Is 1500 watts a lot of electricity? Most electric heaters use 1,500 watts, but some are slightly less or slightly more. Since 1,000 watts equals 1 kilowatt, that means your heater uses 1.5 kilowatts of power. However, your electric bill is measured in kilowatt hours, which is the amount of energy used while running a […]
What muffles sound the best?
What muffles sound the best? The best types of surfaces for absorbing sounds are ones with jagged surfaces and hollow recesses within (much like a sponge or cardboard). The proper object captures the sound waves and bounces them around within the object until the vibrations dwindle. Does Styrofoam deaden sound? Polystyrene foams such as Styrofoam […]
What causes resistance in a wire?
What causes resistance in a wire? The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow, and causes resistance. The resistance of a long wire is greater than the resistance of a short wire because electrons collide with more ions as they pass through. […]
What do we call a ramp and ladder combined?
What do we call a ramp and ladder combined? A wedge is a simple machine that is made of two inclined planes together. Inclined planes don’t move, but wedges do. An axe is an example of a wedge. Inclined planes are simple machines used to make work easier. Ramps, ladders, and staircases are all inclined […]
What happens when an atom gains or loses an electron quizlet?
What happens when an atom gains or loses an electron quizlet? When an atom loses an electron, it loses a negative charge and becomes a positive ion. When an atom gains an electron it gains a negative charge and becomes a negative ion. What kind of bond is formed when two atoms share an electron? […]
Why did US not join League of Nations?
Why did US not join League of Nations? The League of Nations was established at the end of World War I as an international peacekeeping organization. Although US President Woodrow Wilson was an enthusiastic proponent of the League, the United States did not officially join the League of Nations due to opposition from isolationists in […]
How is food transported in plants explain Class 10?
How is food transported in plants explain Class 10? The phloem tissue in plants transports food materials from the leaves to different parts of the plant. As a result, the osmotic pressure in the tissue increases forcing the water to move through it. This pressure moves the materials in phloem to the tissues which have […]
