Meg and Rachel each have bowling balls with the same mass. They both roll them as hard as they can and then measure the speed of the balls. Meg's ball and Rachel's ball were measured to have the exact same speed. What do you know about the forces applied by the girls?
A) Meg applied more force than Rachel.
B) Rachel applied more force than Meg
.
C) They applied an equal amount of force.
D) They applied a almost the same amount of force.
Meg and Rachel applied the same force because the speed was the same amount of the force. Thus, option D is correct.
What is force?
In general language we can say that push or pull is called force.
According to newton second law of motion force is rate change of momentum it means
F= d/dt×(mxv)
Where m is mass and v is velocity
But in general case mass is constant.
So ,Force
F= mxd/dt×(v)
Since we know that rate change of velocity is acceleration.
Then we can say that
F= mass x acceleration
S.I unit of force is Newton
1 Newton = 1kg×m/sec^2.
Force and acceleration is a physical quantity which have both i.e magnitude and direct it means both are vector quantity. According to newton second law of motion force is rate change of momentum it means
F= d/dt×(mxv)
Therefore, Meg and Rachel applied the same force because the speed was the same amount of the force. Thus, option D is correct.

Under which of the following conditions would a fossil most likely form?
A. a living thing dies and sediment is very slowly deposited on top of its body.
B. a living thing dies and sediment quickly covers its body.
C. a living thing dies and its skeleton is left exposed to the elements.
D. a living thing dies and radioactive element breaks down its body.
Please help I am so confused!!
Answer:
The answer is A) a living thing dies and sediment is very slowly deposited on top of its body.
Explanation:
The formation of a fossil depends a lot on the chemical composition of the organism that has died. Generally, the hard materials of an organism such as bones tend to have a greater amount of minerals within their composition, which facilitates the formation of a fossil. In order for a fossil to form, it is necessary that all the soft tissues of the organism have disappeared and sedimentation of the organism occurs, which prevents decomposition. This fossilization process occurs in thousands of years.

What is the common name of this gas, N2, the most prevalent in our atmosphere? A) sodium B) nickel C) nitrogen D) oxygen
Answer: The correct option is C) Nitrogen.
Nitrogen ( N₂) is the most prevalent gas in the atmosphere. It contributes 80% in the atmosphere. It is a highly stable gas because it contains three bonds between the two nitrogen atoms. So, it requires high energy to break these chemical bonds.
Nitrogen is the basic nutrient for the survival of all life forms. It is present in bio-molecules like proteins and DNA.
Nitrogen gas can not be used as such by the plants and animals. Therefore, it is converted into other forms so that plants and animals can utilize it. The process of conversion of N₂ into other biologically available form is termed as Nitrogen fixation.
The leaves of a plant are dotted with openings known as stomata. When open, stomata allow the plant to exchange gases and allow moisture to evaporate, helping to draw water from the roots up into the plant. These activities help the plant to
maintain homeostasis
synthesize minerals
produce light energy
decompose organic matter
Answer:
The correct answer is "maintain homeostasis".
Explanation:
Homeostasis is a concept used in science to refer to the propensity to have a constant internal environment within an organism. The plants maintain its water homeostasis in the along the whole plant by the dotted opening in its leaves known as stomata. By allowing the exchange of gases through stomata, the plant regulate how much water is presented in the roots and in the plant's body, maintaining an internal environment within the whole organism.

What is the Sun's apparent path through the sky in the northern hemisphere
The Sun's apparent path through the sky in the northern hemisphere forms an arc that changes with the seasons, with longer, higher paths in summer and shorter, lower paths in winter, affecting daylight hours.
The Sun's apparent path through the sky in the northern hemisphere changes with the seasons due to Earth's 23.5° tilt on its axis and its orbit around the Sun. During summer in the northern hemisphere, the path is long, and the Sun rises north of east, culminating at a high point in the sky around noon before setting north of west, resulting in longer days. In contrast, during winter, the Sun takes a shorter path, rises south of east, and sets south of west, spending less time above the horizon and leading to shorter days. On equinoxes, approximately March 21 and September 21, the Sun rises directly east and sets directly west, spending equal amounts of time above and below the horizon.
At noon, the Sun reaches the highest point in its daily journey across the sky, crossing the north-south direction, usually to the south of the observer in the northern hemisphere. This height above the horizon at noon varies with the seasons, reaching its maximum during the summer solstice around June 21 and its minimum during the winter solstice around December 21.

Scientists looked for organic compounds, microfossils, and potential microorganisms in the lunar samples, using thorough laboratory analyses. No signs of life were found on the Moon. The samples still provide valuable information for scientific research about lunar history.
Explanation:
When the Apollo astronauts brought back samples of the Moon's surface, scientists searched for evidence of life by examining these samples for organic compounds, microfossils, and any possible living microorganisms. They used various types of analyses, such as microscopy, chemical analysis, and culturing techniques. Despite the detailed examination of nearly 400 kilograms of lunar material, no signs of life were found on the Moon. The studies did provide invaluable insight into the Moon's composition and history, including its formation about 4.5 billion years ago. Since then, the samples returned from the Apollo missions have continued to be of scientific value, enhancing our understanding of lunar geology and the early Solar System.
The comprehensive study of lunar soil and regolith also confirmed that it had been pulverized by impacts, as suggested by the Surveyor missions, and was firm enough to support the Apollo Lunar Surface Experiment Package (ALSEP) which operated for years after deployment. Such detailed analysis has been crucial to expanding our knowledge of the Moon and has left a lasting legacy, with the lunar material collected still providing data for current scientific research.
