Answer:
Hurricanes and tropical storms gain their power from heated water evaporating from the ocean.
Explanation:
<h3>Brown Water Effect </h3>
- The brown ocean effect is an observed weather phenomenon involving some tropical cyclones after landfall. Normally, hurricanes and tropical storms lose strength when they make landfall, but when the brown ocean effect is in play, tropical cyclones maintain strength or even intensify over land surfaces.
The answer is 0.841 g AgCl
Q. Which object is accelerating?
A: A skateboarder speeding up as he skates down a ramp.
The car is not accelerating as it is travelling at constant velocity. Acceleration refers to the rate of change of velocity of an object over time. Thus, there is no acceleration for the car.
The bicycle is not accelerating as it is decelerating (slowing down). This is not to be confused with accelerating in the opposite direction. Deceleration refers to the rate at which an object slows down. Deceleration is a scalar quantity whereas acceleration is a vector quantity. Yeah.
The final one isn't right, well, because the first two options are wrong.
So through process of elimination, you can deduce that the skateboarder experiences acceleration.
Also, the skateboarder experiences acceleration as he is "speeding up", implying that his speed is not constant and in fact increasing, so there's acceleration.
Joseph Proust is the scientist who provided a foundation for John Dalton's work on the atomic structure.
