Answer: its B
Explanation:
Metal abrasive disks are used as a water coolant. These are used mostly to slice stones and metals. Grit discs have several advantages over various kinds of discs. They have such a relatively fast cutting speed. The grit disc sander is not a hefty instrument that can be easily held when operating on a scaffold.
Steel cutting fluids are abrasive or peening mediums composed of iron particles. They are typically offered in two sizes (shot and grit) that suit various industrial applications. Since these grains are made from smashed steel shot, they have sharp edges and broken parts.Therefore, the answer is "Option B".

A meteor falls toward Earth's surface. Given that the acceleration due to
gravity is 9.8 m/s^2, what is the meteor's potential energy if it has a mass of 10
kg at an altitude of 400 m?
O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

Why does a nucleus always have a positive charge?
Answer:
Explanation:
The nucleus is positive because only protons live in the nucleus. Electrons (which have a minus charge ) orbit around the nucleus, but only the nucleus has positive charges.
A carrot has a volume of 180 cubic centimeters and a mass of 81 grams . Calculate its destiny
Answer:
0.45 grams per cu centimeter
Explanation:
When you drop something, first of all it accelerates.
The faster it falls, the bigger the force of ______ that acts on it.
choose from the list to complete the sentence:
friction gravity air pressure
note: apparently the answer is friction but it doesn't make sense to me so please explain.
The faster an object is going, the more resistance there will be. An example of this would be if you're running the faster you run, the more air is going against you.
I hope this helps!
What is an ecosystem? Group of answer choices An ecosystem is all different populations of animals in an area. An ecosystem is a community of plants and animals and their physical surroundings. An ecosystem is a single example of a particular species of plant or animal. An ecosystem is all the organisms of a particular kind of species and their surroundings.
Answer: An ecosystem is a community of plants and animals and their physical surroundings
Explanation: An ecosystem is a geographic area where plants, animals, and other organisms as well as weather and landscape work together to form a bubble of life. Ecosystems contain biotic and abiotic factors both. Biotic factors include plants, animals, and other organism
Answer: An ecosystem is a community of plants and animals and their physical surroundings.
Explanation: Ecosystem plays an essential role for the existence of living organisms in the planet Earth. A balanced ecosystem is attained as a result of various reasons it includes the live ratio of diverse varieties of organisms in a particular ecosystem, necessary physical, biological, and chemical conditions that promotes the living of organisms, and the balanced atmosphere attained as the result of temperature, wind, and humidity.
As all the above mentioned properties are necessary for maintaining a sustainable ecosystem, it is clearly understood that an ecosystem is a community of plants and animals and their physical surroundings.

newtons second law states that fotce is equal to mass time acceleration. How does this experiment demonstrate newton's second law?
Answer:
Image result for what's newton's second law
Newton's second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a (acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation.
Motions need an unbalanced net force to maintain.

How does the agricultural activity most likely affect the surface water of the area?
Answer:
Agriculture has been the cause of significant modification of landscapes throughout the world. Tillage of land changes the infiltration and runoff characteristics of the land surface, which affects recharge to ground water, delivery of water and sediment to surface-water bodies, and evapotranspiration.

HELP ASAP!!! ( it’s science not physics) Allen, Chloe, Jaycee, and Kim are all biking at the same speed. At one point, Chloe speeds up and pedals at a new speed for several minutes. She slows down slightly as she rides up a hill. Finally, she slows way down to allow her friends to catch up with her.
The tables show the mass of each bicyclist, the kinetic energy (KE) of each bicyclist at the original speed, and the kinetic energy of Chloe at four different speeds.
Answer:
Answer: The chart for the bikers would start at (925,37) and end at (1250,50). The chart for Chloe would start at (200,2) and end at (4050,9). To also summarize the relationship shown in each graph you would want to put something like,
1. The graph that shows the bikers mass and kinetic energy is linear. As the mass increases the kinetic energy also increases. The line on the graph is straight going up towards the right corner. The graph has about 64 squares making the line look smaller.
2. The graph shown shows Chloe’s speed and kinetic energy. The line on the graph is line. As the mass increases the kinetic energy also increases. The line on the graph is straight going up towards the right corner. The graph has about 25 squares making the line look bigger than the line shown on the first graph.

5. a.An orienteering map is a map specially prepared for use in orienteering events. These maps are much more detailed than general-purpose topographic maps, and incorporate a standard symbology that is designed to be useful to anyone, regardless of native language.
b.
The reason for this choice is that orienteers use a magnetic compass to navigate with, so it makes sense for both map and compass to be utilising the same system.

How does Dr. Hayes' and Dr. Malaska’s research differ? Why are both research projects important?
Answer:
Their research differs because they were both talking about different things, Hayes was talking about how many lakes there were, while Malaska's was doing more hands on stuff like experiments. Both are important because we need to learn how the lakes formed, but we also need to do hands on experiments.
The reason why the research that was conducted by both researchers differed ws due to the fact that Hayes was concerned about the number of lakes while Malaska was experimenting on the lakes.
What was Dr Hayes research:Dr Hayes was an American scientist that was experimenting on the Frog species that are found in lakes.
What was Dr Malaska's research?This researcher was more interested in finding out the components that are found in lakes.
