It's the 1st one im so serious
Answer:
Human Impacts on the Environment. Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Explanation:
Answer: The answer is both conduction and convection. Convection moves warmer water away from you towards cooler water and conduction transfers heat from your body to the cooler water.
Explanation: Water is a much better conductor of heat than air. So when you are surrounded by water, energy can flow from your body (conduction of heat) much more quickly than it would if you were surrounded by air at the same temperature. In fact, even if the water is warmer than the air, you might feel cold when getting into it.

So the acceleration has actually slowed down the ball because it was going in the direction opposite the velocity. Now see what happens as the ball falls back down to Earth. The ball has zero velocity, but the acceleration due to gravity accelerates the ball downward at a rate of –9.8 m/s2.
hope it helps
The answer is: HNO3(aq)+H2O(l) ==> H3O+(aq)+NO3-(aq)
It donates a proton to water, making it into a hydronium ion and turning HNO3 into NO3
