The Sun provides the light that illuminates our planet. Why does the space between Earth and the Sun look so dark?
which material in the pictures above reflects the most light
A mirror, which has a smooth surface, reflects the most light in the pictures.
Explanation:The material in the pictures that reflects the most light is a mirror. A mirror has a smooth surface, which allows for specular reflection of light at specific angles. Specular reflection occurs when light rays strike a smooth surface and bounce off in a regular, predictable manner.
On the other hand, rough surfaces reflect light in many different directions, which is known as diffuse reflection. This is why objects with rough surfaces, like people, clothing, and walls, can be seen from different angles.

When finding the ideal mechanical advantage (IMA), the negative force not being included is ___.
Answer:
When finding the ideal mechanical advantage (IMA), the negative force not being included is friction.
Explanation:
Mechanical Advantage is the ratio between the force exerted by a mechanism and the force applied to it. The simplest example is the lever, where the ratio of forces is equal to the ratio between the lengths of the lever arms. Another example is the system formed by rope and pulley. If the rope passes twice between the upper and lower pulleys, then the mechanical advantage is four to one.
In situations where the ideal mechanical advantage is found, there is a negative force not included, that force is friction.

Dr. Arenas is a scientist who has been trying to determine if increasing pressure will increase the sound that occurs when two chemicals explode. She measures the volume of the sound that occurs at the minimum pressure at which the explosion will occur. She then increases the pressure and measures the volume of the explosions that occur. What kind of investigation is the scientist conducting?
Dr. Arenas is performing a chemistry experiment to test Boyle's Law by investigating the relationship between pressure and the volume of sound from exploding chemicals.
Dr. Arenas is conducting an experimental investigation in the field of chemistry. Her work involves measuring the effect of pressure on the volume of sound produced by the explosion of chemicals. This type of experiment is
linked to Boyle's Law, which describes the inverse relationship between the pressure and volume of a gas when the temperature and amount of gas are held constant. By increasing the pressure on a system, Dr. Arenas is observing whether there is a corresponding increase in the amplitude of sound, implying more energy being released or a change in how the sound propagates under higher pressures.
A historical context to this investigation can be found in the experiments of the Irish chemist Robert Boyle, who was one of the first scientists to establish the quantitative relationship between the pressure and volume of a gas. Boyle's Law is foundational in understanding gas behaviors and is a key concept in chemistry and physics education.
Dr. Arenas' investigation may have practical implications in understanding the dynamics of explosions, which could extend to fields such as engineering and safety science. The results of such an experiment could provide insights into the effectiveness of containment strategies for explosions and may also have relevance in acoustic engineering, where understanding how sound intensity varies with pressure is important.

The distance between Jupiter and the Sun is 5.2 AU. What is the distance in millions of kilometers?
Answer:
777.9 Mkm
Explanation:
(M = Mega = [tex]10^{6}[/tex])
AU is the Astronomical Unit for distance (1AU=149,597,870.691 km)
The total distance in km then is:
[tex]5.2 * 149,597,870.691 km = 777908927.593 km[/tex]
To give the result in millions, we use the prefix Mega:
[tex](\frac{1M}{10^{6} } ) * 777908927.593 km = 777.9 Mkm[/tex]
If four wave crests pass a pole each second:
1. What is the speed of the wave?
2. What is it's period?
The speed of the wave is 4 m/s, and its period is 0.25 s.
Explanation:The speed of a wave can be calculated by dividing the distance traveled by the time taken. In this case, if four wave crests pass a pole each second, and the distance between two successive crests is 4 m, then the speed of the wave can be calculated as follows:
Speed = Distance / Time = 4m / 1s = 4 m/s
The period of a wave is the time taken for one complete wave cycle. Since four wave crests pass a pole each second, the period can be calculated as the inverse of the frequency:
Period = 1 / Frequency = 1 / 4 Hz = 0.25 s
1. The speed of the wave is 4 times the wavelength.2. The period of the wave is 0.25 seconds.
1. To determine the speed of the wave, we need to know the wavelength, which is the distance between two consecutive crests.
[tex]\[ v = \lambda f \][/tex]
where f is the frequency, which is the number of wave crests passing a point per unit time. In this case, four wave crests pass the pole each second, so the frequency f is 4 Hz (hertz). Therefore, the speed of the wave is:
[tex]\[ v = \lambda \times 4 \][/tex]
This means the wave speed is 4 times the wavelength.
2. The period (T) of a wave is the time it takes for one complete cycle of the wave to pass a point. It is the reciprocal of the frequency. The frequency is given as 4 Hz, which means 4 cycles per second. To find the period, we take the reciprocal of the frequency:
[tex]\[ T = \frac{1}{f} \] \[ T = \frac{1}{4} \] \[ T = 0.25 \text{ seconds} \][/tex]
So, the period of the wave is 0.25 seconds. This is the time it takes for one wave crest to pass the pole."

This question refers to the hiker's average velocity during part B of the hike. The accurate answer requires the undisclosed specifics of the hiker's movement during that part. Possible solutions vary in direction (north, south, southeast) and speed (0.6, 0.17, 10, 6 km/h), critical components of velocity.
Explanation:The question is asking for the average velocity of the hiker during part B of the hike. Velocity is a measure of displacement over time in a particular direction, in this case, given as kilometers per hour in a specific cardinal direction. Without the context of the hiker's actual movement or a diagram, we cannot definitively determine the correct answer. The potential answers provided vary in magnitude and direction, both components of velocity. If, for instance, during part B the hiker traveled 1.2 kilometers to the north in 2 hours, his average velocity would be 0.6 km/h north. However, this interpretation is dependent on the specifics of the hiker's journey.

what's one benefit and one limitation of comparative investigations
Answer:
I will go with the obvious answers, but those are really impactful in some situations:
Benefit: You have much completer results, this is because you have, at least, two sets of data (that you know that are reliable because is most likely that you collected them)
This gives a wider range of application of the model or the results obtained of the investigation, and it allows to notice some anomalous behaviors in some cases (for example if you are studying how metal conducts electricity at different temperatures, you may found the point where it turns into a superconductor, and this gives a lot of information when investigating)
Limitation: You need to collect more than one set of data. This not only needs more time to acquire the data, but this also may need more equipment, more money, and more time to analyze the data.

How big is the image produced by the periscope compared to the size of the object
The size of the image produced by a standard periscope without additional magnifying lenses is the same as the size of the object. If the periscope includes magnifying lenses, the image could be larger due to the magnification effect caused by the lens focal lengths.
The size of the image produced by a periscope is generally the same as the size of the object being viewed. Periscopes use a set of mirrors or prisms to reflect light from the object to the viewer's eye without altering the size of the image. Since a periscope is primarily used to redirect the line of sight rather than to magnify, unless specifically designed with magnifying lenses, the image maintains the same proportions as the actual object.
In the case where a periscope might include magnifying lenses, like those sometimes found in submarines, the size of the image could be larger than the object. However, this would be due to the magnification provided by the lenses, much like with telescopes detailed in the given references. In optics, the magnification of an image is a function of the focal lengths of the lenses involved. If we think of common telescopic systems, the angular magnification is the ratio of the angle subtended by the image to the angle subtended by the real object. When translated to periscopes with added lenses, a similar principle of magnification determining the size of the image compared to the object applies.
