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 […]

Is Pioneer 10 still transmitting? After more than 30 years, it appears the venerable Pioneer 10 spacecraft has sent its last signal to Earth. Pioneer’s last, very weak signal was received on Jan. 22, 2003. The last time a Pioneer 10 contact returned telemetry data was April 27, 2002. Is Voyager 1 dead? Voyager 1, […]

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 […]

Can u have a rainbow without rain? The rainbow without rain is possible, and means that there is a little moisture in the air or the sun is shining through the edge of a cloud. These sorts of clouds are caused by especially tiny ice crystals or water droplets in the air. What happens if […]

Where do unused calories go? When you eat more calories than you need, your body stores the extra calories as body fat. Even a fat-free food can have a lot of calories. Excess calories in any form can be stored as body fat. How many excess calories must you burn to lose one pound? You […]

Does anything have 100 efficiency? A system can never be 100% efficient. The reason behind this is because of heat and sound energy are lost in some amount in every system. No matter they are waste or not. So a system doesn’t exist, with 100% efficiency. Is human body energy efficient? Alas, our bodies are […]

Is it possible for mineral to have a prismatic habit without having any cleavage? Answer Expert Verified Yes, this is possible for prismatic crystal habit to have no cleavage such as in the case of quartz. Quartz usually has well developed hexagonal prismatic crystals but at the same time has no cleavage. What is mineral […]

How are potential and distance related? Moving towards and away from the charge results in change of potential; the relationship between distance and potential is inverse. For one point charge, potential will be constant for all points a certain radial distance away. Multiple points of the same potential are known as equipotential. How do you […]
