The correct answer would be D. "It's impressive to think about how space technologies can be used on Earth." This sentence accurately summarizes the main idea of the source while maintaining an objective tone. The article discusses how technology developed for managing lunar dust can be adapted for use in combating air pollution on Earth. It highlights the innovative approach of using space technologies for larger purposes to benefit humanity.
To address the research question, "How are substances found on the Moon different from those found on Earth?", the best quotation from the source is:
A. "Moon dust isn't like the stuff that collects on a bookshelf or on tables – it's ubiquitous and abrasive, and it clings to everything."
This quotation provides relevant information about the unique characteristics of moon dust, highlighting that it is different from common household dust. It emphasizes that moon dust is ubiquitous, abrasive, and clings to everything, indicating that its properties are distinct from substances found on Earth. This aligns with Jamie's research question, as it focuses on the differences between substances on the Moon and Earth.
The fact from paragraph 9 that is the best choice for meeting Marty's goal of developing his research with facts appropriate for 9th grade students is option C: "The Canary-S takes measurements that are sent off every minute."
This fact is the most relevant and understandable for a 9th grade audience as it explains a key feature of the Canary-S device. It highlights that the device constantly takes measurements of various pollutants and sends the data to a secure cloud every minute. This fact demonstrates how the technology is designed to monitor air quality in real-time, making it suitable for Marty's research on how Earth's technology can be used in outer space.
Option A, "Batteries can use cellular energy to transmit data," is not as relevant to Marty's research question and does not directly address the use of Earth's technology in outer space.
Option B, "The Canary-S is powered by cellular energy and solar power," is accurate but does not specifically address the fact of taking measurements every minute, which is important for Marty's research goal.
Option D, "Carbon monoxide, methane, and sulfur dioxide are all found on Earth," is a true statement but it does not directly relate to the technology of the Canary-S device or its use in outer space.
The meaning of the word "ubiquitous" as used in paragraph 1 is option C. "found everywhere at all times."
In the context of the paragraph, the author is describing moon dust and emphasizing that it is not like ordinary dust that collects on bookshelves or tables. The word "ubiquitous" suggests that moon dust is present everywhere on the moon's surface and not limited to specific areas. It indicates that moon dust is pervasive and can be found in abundance throughout the lunar environment. Additionally, the word "ubiquitous" implies that moon dust poses a significant challenge and inconvenience, as it clings to everything, even breaking the vacuum NASA designed to clean the moon dust off Apollo spacesuits.
The best textual evidence that supports the idea that moon dust is difficult to detect with the human eye is option B: "It’s so bad it even broke the vacuum NASA designed...". This evidence suggests that moon dust is not only challenging to clean, but it is also abrasive and clings to everything. The fact that it broke the vacuum designed specifically to clean the moon dust off Apollo spacesuits indicates the difficulty in detecting and managing its presence. Therefore, option B is the most suitable choice to support the idea that moon dust is difficult to detect with the human eye.
Answer and explanation: This is a Robinson map of the world. The Robinson projection was created in 1963 by the geographer Arthur Robinson. The projection seeks to balance different types of distortion. The projection isn't perfect, but it is considered more visually appealing than others. It balances small distortions of area, shape, distance, and direction.
Answer:
Their goal was not only to separate South Africa's white minority from its non-white majority, but also to separate non-whites from each other, and to divide black South Africans along tribal lines in order to decrease their political power.
Strategists in the National Party invented apartheid as a means to cement their control over the economic and social system. Initially, aim of the apartheid was to maintain white domination while extending racial separation. ... With the enactment of apartheid laws in 1948, racial discrimination was institutionalized.
Thus question lacks a picture or option, but nevertheless:
Answer:
There are 3 types of friction:1) Static friction - when you apply force and the object does not move.2) Sliding friction - when the surface if the object moves on other.3) Rolling friction - when any wheel or ball moves on any surface rolling friction is applied. it is very less than sliding friction.
