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.
b is true This is an impulse question: Impulse is measured by force x time applied It produces a change in momentum equal to that impulse So, a, c) A large force applied for a very short time might not change an objects momentum much d) Similarly, a small force produces a large change in velocity (or momentum) ONLY if it is applied for a long time.
