Fernando is an engineer at an amusement park who is experimenting with changes to the setup for a magnetic roller coaster ride. In one ride, there are two identical roller coaster cars (red and yellow) that start on opposite sides of a large magnet located in the center of a station. He moves both cars, so each car ends up one space farther away from the large magnet.
How did the potential energy of the two cars change? Did the potential energy of one car change more than the other? Why do you think
Answers
I think that the potential energy of the cars will go down because the cars are moving farther away from the big magnet. Since the pols of the cars and big magnet are opposite and not the same they would want to attract if they got close to the big magnet, but since Fernando is pulling the carts away they loose that potential energy. I also think that the red cart changed more than the yellow cart because it is closer to the magnet which can have a lot of potential energy and he is now bringing the cart away from it. In conclusion, I think the red cart had a greater change in potential energy and the two cars changed in potential energy too.

Answers
No, a bright red coloration would not be the beneficial adaptation for insects that live in the grass.
What is adaptation?Adaptation is a process of change to adapt the body according to the environment to better the living.
In adaptation, any body feature or part changes to better function in the environment.
If a beetle will adapt to red color that live in the grass, it will be easily seen by predators.
It should be colored a color that mix with green color and cant be easily recognized.

A radio wave travels through space with a frequency of 2 x 104 Hz. If the speed of the radio wave is 3 x 108 m/s,
what is the wavelength of this wave?
O 6 x 10^12 m
O 1 x 10^4 m
O 6.7 x 10^-4 m
O 1.5 x 10^4 m
Answers
The wavelength of the radio wave is [tex]1.5 * 10^4[/tex] meters.
The wavelength of a wave is the distance between two adjacent points that are in phase, or in the same phase as their cycles on the wave. For example, the distance between two successive peaks or troughs of a sine wave is known as a wavelength.
A wave's speed, wavelength, and frequency can be calculated using the following formula:
Wavelength = speed / frequency
Substituting the given values:
Wavelength = [tex]3 * 10^8 m/s / 2 *10^4 Hz[/tex]
Wavelength = 15,000 meters or 1.5 x [tex]10^4[/tex]meters
So, the correct option is D.

Rosa drew a flow chart of the carbon cycle. Flow chart of the carbon cycle with 4 boxes connected by arrows. Box 1: carbon dioxide in the atmosphere. Box 2: X. Box 3: consumers eat producers. Box 4: Y. The arrow that follows box 4 connects to box 1. Which labels best complete the flow chart?
Answers
Answer:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
Explanation:
(a) X: Producers undergo photosynthesis. Y: Decomposers return carbon to the soil and release waste.
(b) X: Decomposers return carbon to the soil and release waste. Y: Producers undergo photosynthesis.
(c) X: Decomposers take in carbon dioxide. Y: Producers absorb carbon through their roots.
(d)X: Producers absorb carbon through their roots. Y: Decomposers take in carbon dioxide.
Box 2 (X) would be the process through which producers fix carbon dioxide to produce their own food, the carbohydrate. The process is otherwise known as photosynthesis and can be represented by the following equation:
[tex]6CO_2 + 6H_20 --> C_6H_1_2O_6 + 6O_2[/tex]
Box 4 (Y) would be the process of decomposition. Both producers and consumers eventually die and decompose in the soil. During this process, some of the carbon returns to the soil as organic matters while the process of microbial decomposition releases carbon dioxide into the atmosphere.
The correct option would be (a).

Mr. D asked four students to identify characteristics of organisms in the kingdom Eubacteria. Which student
correctly identified two characteristics of Eubacteria?
Student Cell Organization Nucleus Present
Glenda single-celled
Sam single-celled
yes
Tremica multicellular
no
Thurman multicellular
yes
no
Answers
Answer:
The student who correctly identified the two characteristics of Eubacteria was Glenda (option A).
Explanation:
Eubacteria are unicellular prokaryotic microorganisms, provided with membrane and cell wall.
One of the distinctive characteristics of Eubacteria is their inability to associate and form tissues, as eukaryotic bacteria do, so they are unicellular organisms. In addition, they lack a nucleus, their genetic information is dispersed in the cytosol and they do not possess most of the organelles.
Eubacteria can be found on any surface and some of them can be considered harmful to living beings.
Other options:
None of the other students were able to identify these two characteristics of the Eubacteria.
