Answer:
A) Climate
Hope this helps !
The average weather condition of a region is known as Climate. Thus, the correct option for this question is A.
What are the factors that affect climate?The five main factors which affect the climate of a region are Latitude, Altitude, relief, currents and winds, and distance from the sea. Apart from this, some other natural factors like the shape of the land, distance from the equator, and the El Niño phenomenon, are also responsible for determining the climate of a particular region.
Climate is the long-term pattern of weather in a particular area. Weather can change from hour-to-hour, day-to-day, month-to-month, or even year-to-year. Climate may also be characterized as the average course or condition of the weather at a place usually over a period of years as exhibited by temperature, wind velocity, and precipitation.
Therefore, the average weather condition of a region is known as Climate. Thus, the correct option for this question is A.

Answer:
Law of conservation of mass
Ernest Rutherford
Explanation:
The basic law of behavior of matter that states that "mass is neither created nor destroyed in a chemical reaction or physical change".
This is the law of conservation of mass. It is very essential in understanding most chemical reaction. Also, in quantitative analysis, this law is pivotal.
Ernest Rutherford was the scientist that stated that the nucleus is made up of positive charge. It was not until James Chadwick in 1932 discovered the neutron that we had an understanding of this nuclear component.
Rutherford surmised from his experiment that because most the alpha particles passed through the thin Gold foil and just a tiny fraction was deflected back, the atom is made is made up of small nucleus that is positively charged.

What makes a metal and a non metal most
reactive? Where in the PT will you find the most
reactive metal and the most reactive non metal.?
Answer:
Explanation:
The reactivity of elements in the periodic table is based on the number of electrons in there outermost shell. Elements (metals) that have few electrons in there outermost shell are highly reactive because it is easier to lose fewer number of electrons (in the outermost shell during a reaction) than to lose more electrons in the outermost shell - thus metals that have one electron in there outermost shell are most reactive and are more reactive than those that have two electrons in there outermost shell. Hence, metals in group 1 are the most reactive metals because they all have one electron in there outermost shell.
Non-metals that have fewer electrons to complete there octet configuration are highly reactive because it is easier to gain fewer number of electrons (in the outermost shell during a reaction) than to gain more number of electrons - thus nonmetals that have seven electrons in there outermost shell are more reactive than nonmetals that have six electrons in there outermost shell. Hence, nonmetals in group 17 are the most reactive nonmetals because they contain seven electrons and have just one electron left to complete there octet configuration.
Why does the flow rate of a fluid with large particles increase?
NEED ANSWER ASAP!!!
Answer:
The viscosity of intestinal contents should define the mixing, diffusion and flow of nutrients and other materials in digesta (1–4). The viscosity of intestinal contents has been measured only after the removal of solid particles by centrifugation (5,6), under the assumption that particles or insoluble fibers in the diet do not affect the viscosity of gut contents (7). However, the complete removal of solid particles considerably reduced the coefficient of viscosity of pig cecal contents and changed the contents from a non-Newtonian to a Newtonian fluid in our recent study

When discussing distances between objects in the solar system, which term do you use? (2 points)
Group of answer choices
Actual distance
Apparent brightness
Relative brightness
Relative distanc
When discussing distance in the solar system,you use Relative Distance.This tells you the space between two objects with location.
D. Relative distance
The relative distance is the distance that you are felt to cover up, taking the time used to obtain there. Distance relative to a particular reference point, typically one in motion.
Relative distance is calculated measuring distance, using metrics such as time, effort, or cost.
In space, Relative distance means how far apart the planets are when compared to each other and the sun.
Thus, the correct option is D.

To launch a rocket, liquid oxygen and liquid hydrogen are combined inside the rocket engine to react explosively. How do you think scientists take into account the law of conservation of mass when they calculate the amount of fuel needed for a rocket launch?
Answer:
Explanation:
In this chemistry lab, students investigate how to build and launch a simple rocket that uses hydrogen and oxygen gases that will be mixed to propel the rocket (large bulb plastic pipette). Students will understand the principles of combustion reactions, kinetics, stoichiometry of reactions, activation energy, explosive mixtures, rocketry, and different types of chemical reactions. Students will explore and determine the proportions of hydrogen and oxygen mixture that will achieve the best launch results. Students will compare the balanced chemical reaction of hydrogen and oxygen with their lab results; students should discover that the optimal distance occurs when the mixture of hydrogen and oxygen is two to one hydrogen, oxygen mixture ratio and this can be determined theoretically from the balanced chemical reaction equation. Students will perform the lab, collect data, and discuss, compare, and contrast their lab findings with the balanced chemical reaction equation. Students will present their structured inquiry investigations using a power-point presentation. Other groups along with the teacher will assess each group by using a provided rubric. Group assessments will be the deciding assessment for the final lab score. A follow up activity could investigate how NASA scientists launch real rockets into space and propose a procedure to investigate and collect data on a launching a heavier object at the school football field.
