Asmall boat is moving at a velocity of 1.93 m/s when it is accelerated by a river current perpendicular to the initial direction of motion. if the acceleration of the current is 0.750 m/s2, what will be the new velocity of the boat after 19.3 s?

v = 16.405 m/s  

Explanation:

The velocity v with a constant aceleration could be calculated by:

where the initial velocity, a the aceleration of the current and t the time.

replacing the data:

v = 16.405 m/s

So, the new velocity of the boat is 16.405m/s.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

b would be the answer
