Angelina wants to observe what will happen when two rocks with different masses are pushed down a slide. Angelina puts the two rocks at the top of the slide and pushes each rock with an equal force. Below the slide, Angelina's friend Mary stands to catch the sliding rocks. Based on Newton's law of force and acceleration, what happens to the rocks as they are traveling down the slide?
A) The acceleration of each rock is equal to zero.
B) The rock with the smaller mass has less acceleration than the larger rock.
C) The two rocks have the same acceleration.
D) The rock with the larger mass has less acceleration than the smaller rock.
Answer:
I believe it is D
Explanation:
I think it's D because if something has more mass, it carries more weight, weight slows stuff down. I might be wrong and I am sorry if I am.
Explain how plate tectonics are responsible for where we find some of our natural resources.
Most of our natural resources are embedded beneath the subsurface at different depth. These resources could find their way to depths and positions where that can be mined or to surface at divergent plate boundaries.
Divergent plate boundaries marks the positions where the earth's plates move apart and causing uplift. At this boundary, several resources beneath the subsurface may rise as pressure is eased.
Therefore, the presence of certain natural resources could be due to the occurence of plate tectonics.

What is the relationship between a front and cloud formation?
Here's a little more info
When conditions are right, two air masses can come together and make a tornado. A humid and warm air mass from the south meets a cold and dry air mass from the north, and the cold air moves under the warm air. This creates a low pressure area, drawing air up and in. The air rotates as it rises, gathering speed and forming a funnel.
Answer:
Cold air is more dense than warm air, so when a warm air mass meets a cold air mass, the cold air ends up below the warm air. Once the air has risen, it cools and clouds can form. Weather fronts can cause clouds to form.
Answer:
Weather fronts can cause clouds to form. Fronts occur when two large masses of air collide at the Earth's surface. Warm fronts produce clouds when warm air replaces cold air by sliding above it.

Extension Activity: The Coca-Cola Company has been getting angry letters from drinkers of Diet Coke. Because their soda weighs less they feel like they’re getting ripped off. If they pay the same amount for a diet coke it should have the same amount of soda in it. It is your job as manager of customer relations to answer these angry letters.
For homework, write a sample letter to be approved by the company president that contains the following: A scientific explanation of why the Diet coke weighs less and a sentence or two addressing the customer’s concerns that they are getting less soda than in a regular can or bottle. Remember – your next promotion depends on how well you solve problems for the company!
Your sample letter should contain at least five good sentences: at least three for the scientific explanation plus two more addressing the customer’s concerns. Explain the formula for density and how it is measured.
Some numbers that might help you are:
Coke
