It is tornado that is formed over a water body, usually an ocean or sea.They are similar to the mesocyclonic thunderstorm tornadoes but are formed over a water body. A waterspout is not a destructive tornado as it spans itself over less than 2 km. Tornadoes of these type cause damage that tends to be EF2 or less.
The impulse of force is commonly used to calculate forces in collisions. Active formula Impulse = Average force x time = mass x change in velocity. Enter data below and then click on the desired quantity in the active formula above.
That's what Ohm's law describes. Ohm's law is often written as V=IR, but it is probably more intuitively understandable if you write it V/R = I. Voltage and Resistance are the independent variables, the current is the dependent variable. If you increase the voltage, the current increases proportionally.
