The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes. The more acid that is introduced to the ecosystem, the more aluminum is released.
Some types of plants and animals are able to tolerate acidic waters and moderate amounts of aluminum. Others, however, are acid-sensitive and will be lost as the pH declines. Generally, the young of most species are more sensitive to environmental conditions than adults. At pH 5, most fish eggs cannot hatch. At lower pH levels, some adult fish die. Some acidic lakes have no fish. Even if a species of fish or animal can tolerate moderately acidic water, the animals or plants it eats might not. For example, frogs have a critical pH around 4, but the mayflies they eat are more sensitive and may not survive pH below 5.5.
Effects of Acid Rain on Plants and Trees:
Dead or dying trees are a common sight in areas effected by acid rain. Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow.
At high elevations, acidic fog and clouds might strip nutrients from trees’ foliage, leaving them with brown or dead leaves and needles. The trees are then less able to absorb sunlight, which makes them weak and less able to withstand freezing temperatures.

Answer:
See below
Explanation:
Each resistor has 6 v applied across it
rememeber
V = IR then V/R = I
f<u>or the 6 Ω 6 v /6Ω = 1 amp</u>
<u>for the 3 Ω 6v /3Ω = 2 amp</u>
Answer:
Using insulating materials is the best way to prevent heat transfer by conduction and convection. Insulating materials are poor conductors of thermal energy and also limit the movement of air in spaces, reducing convection. Insulation slows the rate at which unwanted energy enters the home in the summer.

Easy peasy.
Hi,
Have you ever been skydiving?
No I haven't.
Is this something that you would ever want to do?
No, I wouldn't want to do this.
What is the force that is acting against gravity when things fall to the ground from thousands of feet above sea level?
Either air friction or drag.
How do Swati and Banks adjust their body position during a skydiving jump so they can fall at the same rate?
You need to move your arms and legs in different positions for your body to turn and go faster or slower.
During a free fall Swati was accelerating at -9.8m/s2. After 120 seconds how far did she travel? Use the formula =1/2 * t2 to solve your answer. (Do not forget to keep units in your answer.)
58.8km.
