What is the difference between a pelican and a puffin crossing? Puffin. Crossings differ from Pelican crossings, as they do not have a flashing green man/flashing amber signal. This layout encourages pedestrians waiting at the crossing to look at the approaching traffic at the same time as looking at the red man/green man signal. Who […]
What is the process of an electromagnet?
What is the process of an electromagnet? An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole, denoting the center of the coil. […]
Can the resultant of 3 vectors be zero?
Can the resultant of 3 vectors be zero? Answer. Three vectors are coplanar which means all three vectors are in the same plane. If direction of resultant of those two vectors is exactly opposite to the direction of the third vector. If all above conditions are satisfied, then the resultant of three vectors will be […]
How do you write 78000 in scientific notation?
How do you write 78000 in scientific notation? To write 78,000 in scientific notation: 70, 000 = 7×10. 7.8×104 (Note that 78,000 is a whole number, so we dropped the zeros) How do you write 0.002 in scientific notation? Therefore, the decimal number 0.002 written in scientific notation is 2 × 10-3 and it has […]
How do I make my bestie miss me?
How do I make my bestie miss me? Understand the squabbles and disputes among groups of young people are common. Stop talking so much when you are with your friends. Don’t be too touchy-feely. Don’t appear uninvited. Keep yourself busy. Don’t be the one to start the chat in social networking sites. Disappear now and […]
What is the formula for acceleration using distance and time?
What is the formula for acceleration using distance and time? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes […]
What planets have humans landed on?
What planets have humans landed on? All three of those stages have been carried out for the Moon, Venus, Mars, Jupiter, Saturn, a comet, and several asteroids. Several Soviet and U.S. robotic spacecraft have landed on Venus and the Moon, and the United States has landed spacecraft on the surface of Mars. Does moon affect […]
Can u have a rainbow without rain?
Can voltage drop be greater than source?
Can voltage drop be greater than source? The source voltage is only 10 Volts, but the individual voltage drop across resistor and inductor are 6 Volts and 8 Volts respectively, which is greater than the source voltage. … Can voltage be higher than source? You can have a circuit where a component can have a […]
What is the relation between area and resistance?
What is the relation between area and resistance? Resistance depends on an object’s size, shape, and material. In Figure 3 below, the cylinder’s resistance is directly proportional to its length l. The longer the cylinder, the higher the resistance. Additionally, the resistance is inversely proportional to the cross sectional area A. What happens to the […]
