This magnet attracts the compass and the magnetized needle without having to come in contact with them. This is an example of a force acting at a distance.
Which of the following is another example of a force that acts at a distance without actual contact?
-
Wind turning a windmill.
No. The moving air is pushing against the blades of the windmill. Because a physical object (moving air) is pushing on the windmill, this is a contact force. -
Sound causing you to hear something.
No. For you to hear a sound, the vibrations of the object make the air vibrate. That is a contact force because there is direct contact between the vibrating object and the air. The vibrating air is in contact with your ear drum, causing it to vibrate too. That lets you hear the sound. Because a physical object (vibrating air) is moving your ear drum, this is a contact force. -
Gravity causing a rock to fall.
Yes. The gravitational attraction between the Earth and the rock does not need physical contact. The rock would fall, even if it was in a total vacuum, with no physical object to push or pull on it. This is a force acting at a distance. -
Throwing a ball to knock over a target
No. To throw the ball, your arm pushes against it. Your arm moving the ball is a contact force. The moving ball hits the target to knock it over. The ball is touching the target to knock it over, so this is also a contact force.

This is the mineral galena. What type of luster does it have?
-
Vitreous
No. A vitreous luster means that the mineral looks glassy. Galena does not look like it is made of glass. -
Shiny
No. Shiny is not a type of luster. -
Metallic
Yes! A metallic luster means that the mineral looks like it is made of metal. Galena reflects light in the same way that a piece of metal does. If a mineral looks like it is made of metal, it has a metallic luster. -
Silver
No. Silver is a color, not a type of luster. Luster is the way that a mineral reflects light, not is color.

None of these layers have been turned upside down. Based on the Law of Superposition, which layer is the oldest?
-
A
No. Layer A is on top of layer B, so it is younger than layer B. That means that it is not the oldest. -
B
No. If you look at layer B, it is on top of layer C, which means that it is younger than layer C. B is not the oldest. -
C
No. Look closely at the top part of layer C. The top part of layer C is on top of part of layer D. That tells us that layer C is younger than layer D. -
D
Yes! This one is a bit tricky, because of the way the rocks were formed. Layer D formed first, as a flat, horizontal layer. Erosion weathered the left part of D away, forming a sloping hillside. Image the photo with layers A, B, and C erased, and it looks like a sloping hillside.Next, a nearby volcano erupted, spewing out lots of volcanic ash. The ash covered the hillside, forming layer C.
Next, lava from the volcano flowed down over the ash, forming layer B.
Later, the volcano erupted again, depositing another layer of volcanic ash to form layer A. After that, layer A was covered by another layer of lava, and then another layer of volcanic ash.
So A is the youngest, followed by B, then C, and D is the oldest.

I want to test a new fertilizer, to find the best concentration for my garden. To do this, I plan to divide my garden into four sections.
Section A. I will use 5 grams of fertilizer per gallon each time I fertilize.
Section B. I will use 10 grams of fertilizer per gallon each time I fertilize.
Section C. I will use 15 grams of fertilizer per gallon each time I fertilize.
For section D, how much fertilizer per gallon should I use?
-
20 grams of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
30 grams of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
1 gram of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
No fertilizer at all.
Yes. For this type of experiment, you need to have a control group. That is a group of test subjects that you do not do anything to. If the control group with no fertilizer grows just as well as the other groups, then I would know that the fertilizer was not working.

When water freezes into ice, its volume increases. What happens to its mass?
-
It increases.
No. When water freezes, it takes up more space, but the mass stays the same. -
It stays the same.
Yes. When water freezes, it expands to take up more space, but its mass stays the same. Mass is the measure of how much "stuff" is there. Freezing water does not create new water or add more "stuff". It just makes the water take up more space. -
It decreases.
No. The mass stays the same, even when the water freezes. -
Water does not have mass.
No. Everything that is made out of matter has mass.
