What causes it to form: <span>Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain. Human activities, power plants, and exhaust from vehicles all are causes.</span>
Affects on living things-
Acid rain can kill trees
It can affect plant growth patterns
Toxins can kill animals
Nonliving things-
It can decay building materials and paints
it breaks down rocks

If an object whose mass is growing keeps the same, unchanged
kinetic energy, then its motion must slow down, because
Kinetic Energy = (1/2) (mass) (speed)² .
Answer:
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.
Explanation:
Assuming the machine is a simple machine, such as a lever or pulley, the machine will not do any more work than is put into it. However, it can change the magnitude or direction (or both) of the input force required to achieve a particular output force.
Because the machine does not increase the work done, if the output force is greater, the output distance must be less.
The applicable observations are ...
- It can put out more force than the input force by decreasing the distance through which force is applied.
- It can apply a force to an object in a different direction than the force applied to the machine.

The polaris is a star which appear to stand still while the rest of the stars move due to the rotation of the earth.If u are standing at the north pole the polaris would be directly above you.To find the polaris u must first find the big dipper which is like a bowl with handle and the move like 5 time to find the polaris
