what can be found if the apparent magnitude and the distance to a star are known?
A.
velocity
B.
age
C.
absolute magnitude
D.
color

Answers

Answer 1

Answer:

C.  absolute magnitude  

Explanation:

absolute magnitude = apparent magnitude - 5log(distance)  

Thus, if you know the apparent magnitude and the distance, you can calculate the absolute magnitude.

Answer 2

If the apparent magnitude and the distance to a star are known the Absolute magnitude can be found.

Answer: Option C

Explanation:

The scale of the relative brightness of the star and other astronomical object that is viewed by the observer is commonly called as Apparent magnitude. The apparent size of the object depends on the internal brightness, distance and decay of light from the object by interstellar dust along the viewer.  

It is a measure of the brightness of the star. Astronomers estimate the size of a star on a scale where the number of bright stars is smaller and the number of dark stars is greater by the Apparent magnitude. In the night sky, Syria is known for the brightest star.

What allows us to apply normal calculations to non-normal distributions?

Answers

Answer:

Explanation:

Many data sets naturally fit a non normal model. For example, the number of accidents tends to fit a Poisson distribution and lifetimes of products usually fit a Weibull distribution. However, there may be times when your data is supposed to fit a normal distribution, but doesn’t. If this is a case, it’s time to take a close look at your data

The central limit theorem allows us to apply normal calculations to non-normal distributions

The central limit theorem states that if you have a population with mean μ and standard deviation σ and take sufficiently large random samples from the population with replacement , then the distribution of the sample means will be approximately normally distributed.

What is central limit theorem formula?

Central limit theorem is applicable for a sufficiently large sample sizes (n ≥ 30). The formula for central limit theorem can be stated as follows: μ x ― = μ a n d. σ x ― = σ n.

What are the three rules of central limits theorem?

It must be sampled randomly. Samples should be independent of each other. One sample should not influence the other samples. Sample size should be not more than 10% of the population when sampling is done without replacement.

Name at least three eco-driving techniques you can use to increase your gas mileage and extend the life of your vehicle.

Answers

How to drive Eco-Driving:

First, increase vehicle speed slowly or not in a hurry. Second, keep a stable speed and safe distance with other vehicles. Third, slow down the speed by releasing the accelerator, not by stepping on the brake and accelerator simultaneously. Fourth, use air conditioning as needed. Fifth, do not heat the engine or leave the engine running when the car is not in use. Sixth, prepare travel plans well and avoid crowded routes. Seventh, check tire pressure regularly and carry luggage as necessary and not excessive. Eighth, obey parking rules and traffic signs and lastly, always check and read the fuel-saving indicator.

Further explanation

Eco-Driving is one of the developments that is considered as a pioneer of environmentally-friendly driving. In its application, many benefits are obtained by the driver, especially four-wheeled vehicles.

Eco-Driving is a way of driving that aims to optimize fuel consumption efficiently and play a role in reducing the risk of accidents on the highway. Besides being efficient, the application of the Eco Driving technique also contributes to the environmental preservation program by reducing the contribution of CO2 gas which has been the third-largest source of carbon emissions.

The following are important points in applying the Eco Driving technique:

Press the accelerator slowly. Starts with high acceleration will only cause excessive fuel consumption. Doesn't overload the engine with excessive RPM rotation. Limit shifts to 2000 RPM so that fuel usage remains optimal. Keep a safe distance from the car in front, 2-3 meters is the recommended distance. Smooth pressure on the gas pedal when stuck. Rarely do the legs half clutch position. Utilization of engine breaks for braking. Avoiding the engine running too long when idling. It's good to turn off when stopped for more than 10 minutes. AC temperature in an ideal position, not at maximum temperature. Close the window at high speed. Not aggressive when driving.

Using social media to support activities such as producing maps and incident visualizations is an example of which communication standard

Answers

Answer:

The correct answer would be Technology Use and Procedures communication standards.

Explanation:

Communication standards are the standards that are used to communicate, used to send and receive data and information from one point to another. Standards consists of predefined syntax, semantics and synchronization of all communication that is done digitally. This could be hardware, software or both. So when social media is used to support activities such as producing maps and incident visualizations, the communication standard that is running behind this transfer is Technology Use and Procedures. This standard is actually a tool to increase situational awareness for the public and the incident management.

The answer is option C. Using social media to support activities is an example of technology use and procedures.

Technology Use and Procedures involves the implementation and utilization of various technological tools and processes to enhance communication, data sharing, and operational effectiveness during incidents. Using social media for producing maps and incident visualizations falls under this category because:

Technology Integration: Social media platforms are being used as a technological tool to collect, analyze, and disseminate information.Enhanced Communication: This practice improves communication by providing real-time updates and visual representations of incidents, which can be crucial for effective decision-making and coordination.Operational Support: The use of social media aids in operational tasks by offering a dynamic and interactive way to visualize incidents, track developments, and share information with the public and response teams.

By leveraging these technologies, organizations can improve their response strategies and situational awareness, making Technology Use and Procedures the most appropriate communications standard in this context.

The question is:

Using social media to support activities such as producing maps and incident visualizations is an example of which communications standard?

A. Common Terminology, Plain Language, and Compatibility

B. None of the Above

C. Technology Use and Procedures

D. Information Security/Operational Security

Explanation:

Once a teacher has established the subject he/she is approaching, it is possible to delineate some definit goals for the course, to transform those goals into objectives afterwards.

A goal and an objective are different in that a goal serves as a guide, but an objective can be measured. Objectives work as tools to evaluate the progress of the students. They also set up how much the goal will approach. Once the teacher realizes that class has learned the material, he/she can confidently advance to other teaching goals or curricular domains.
