Most earthquakes occur in areas close to where tectonic plates meet. There are earthquakes in San Francisco. What can be concluded from this information?
A) San Francisco is far away from an area where tectonic plates meet.
B) San Francisco is close to an area where tectonic plates meet.
C) San Francisco is close to Luzon, an island in the Philippines.
D) San Francisco is likely to experience a volcanic eruption in the near future.
Answer:
B) San Francisco is close to an area where tectonic plates meet.
Explanation:
According to the question most earthquakes occur in areas close to where tectonic plates meet. The best option that can be concluded from the earthquakes occurring in Francisco is that San Francisco is close to an area where tectonic plates meet. The close proximity of San Francisco to where tectonic plates meets will likely cause earthquake in that region.
Generally, the earth is divided into different plates. These tectonic plates might be oceanic crust or continental crust. The plates are constantly moving. The plates might be moving away from each other(divergence) , colliding with each other(convergence) or moving past each other (transform).
The area where these plates meets are usually area of potential earthquakes. This boundary are area of minor or major earth quake. Usually , aesthenospheric material are introduce to the surface through this boundary.

how is a pure substance different from a mixture? A. mixtures can be separated by physical means B. Pure substances are made up of mixtures C. A pure substance is heterogeneous D. A mixture is made of one substance
Mixtures can be separated by physical means is the statement that describes how a pure substance different from a mixture.
A pure substance is a form of matter that has a definite (constant) composition and distinctive properties.
On the other hand, a mixture is a combination of two or more substances in which they retain their properties.
Any mixture can be formed and then separated by physical means into its pure components without changing the identity of those components.
That is, there are different methods to separate a mixture into its different components, these methods are physical since they do not alter the properties of the components.
These physical methods are: Filtration, decantation, distillation among others, and are based on the physical state, characteristics and properties of the components of the mixture, to use the most appropriate technique.
Therefore, we can conclude that mixtures can be separated by physical means is the statement that describes how a pure substance different from a mixture.

If I spacecraft seems to be Motionless in deep space is given some type of quick push what will happen
Answer:
Will remain in motion until an external force is applied.
Explanation:
According to Newton's first law of motion, a body continues to be in state of rest or motion, until and unless an unbalanced, external force acts on it.
In deep space, there is no external force. If a motionless spacecraft uses thrusters to give a push, the spacecraft will continue to be in motion until an unbalance external force acts on it again to stop it or increase its speed or change direction.
If the labor force of 155 million people is growing by 1.2 percent per year, how many new jobs have to be created each month to keep unemployment from increasing?
Answer:0.155 million jobs have to be created each month to keep unemployment from increasing.
Explanation:
Population of the labor force = 155 million
Percentage increase of labor force in an year = 1.2 % of 155 million
Percentage increase in labor force in a month = [tex]\frac{1.2 \%}{12}=0.1 \%[/tex] of 155 million
Jobs required to be created each month = population increase each month
[tex]=155 million\times \frac{0.1}{100}=0.155 million[/tex]
0.155 million jobs have to be created each month to keep unemployment from increasing.
Final answer:
To maintain the current unemployment rate with a labor force of 155 million growing at 1.2% annually, 155,000 new jobs need to be created each month.
Explanation:
To determine how many new jobs have to be created each month to keep unemployment from increasing, given a labor force of 155 million people growing at 1.2 percent per year, first, calculate the annual growth of the labor force. Multiply the current labor force by the growth rate:
155 million * 0.012 = 1.86 million new entrants into the labor force per year.
To find the monthly job creation requirement, divide this annual number by 12:
1.86 million / 12 = 155,000 jobs per month.
Therefore, 155,000 new jobs need to be created each month to keep unemployment from increasing as the labor force grows.

How can the rate of a reaction be increased?
lowering the temperature
decreasing the amount of reactants
having more surface area
diluting a solution
Answer:
C. Having more surface area
When the reaction involves solids, an increased surface area of it will result in an increased reaction rate. The higher the temperature, the faster the reaction rate will be too. Lowering the temperature, decreasing the amount of reactions, and diluting a solution will decrease the reaction rate
Answer:
having more surface area
