Answer:
Ethos, because she is using her own knowledge as a tool.
Explanation:
Harriet Tubman was an activist and served as a spy for Union Army. 'Harriet Tubman: Conductor on the Underground Railroad' is a book written by Ann Petry narrating the accounts of life of Harriet Tubman who helped free 300 slaves using the paths of Underground Railroad.
In the given excerpt, Tubman has used the rhetorical appeal of 'ethos' as she is using her own knowledge as a tool. While rescuing slaves using Underground Railroad, Tubman made up several stories to keep the slaves moving and encourage them in their paths of freedom. The path for freedom was dangerous, and Tubman knew that some may back up from this, so she kept telling them about people who chose to struggle for freedom, made up stories about them and used this knowledge as a tool to keep the slaves encouraged and motivated. And no one asked her even one question as they trusted her (credibility-- element of ethos).
Thus, the tool Tubman has used in the given excerpt is ethos.

The more gravity pulls down on an object the less the object weighs true or false
false
Explanation:
The more gravity pulls down on an object it gets heavier. Weight is just the amount of force gravity is putting on something. So if gravity is pulling it down more ut would get heavier.
Answer:
False
Explanation:
The move gravity there is pulling on something, the more it'll weigh. The less gravity something or someone has, the less they will weigh. For example, on the moon things weigh less because there is less gravity pulling on objects.

Tony ran at a constant speed of 10 m/s for a total of 60 seconds. How far did he run?
According to the speed formula, distance that Tony ran at a constant speed of 10 m/s for a total of 60 seconds is 600 meters.
What is speed?The speed (commonly referred to as v) of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity.The average speed of an object in an interval of time is the distance traveled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity.
Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used.

how do you convert L to mL
Answer:1 Liter (L) is equal to 1000 milliliters (mL). To convert liters to mL, multiply the liter value by 1000. For example, to convert 2 liters to mL, multiply 2 by 1000, that makes 2000 mL is 2 L.

I have a block of gold and the density is 13.54g/ml If I cut the block in half what is the density of the smaller pieces of gold
Answer:
Density is the same
Explanation:
The density remains the same because cutting the object in half will divide the mass & volume by the same amount. Also, the density of a substance remains the same no matter what size it is.

Explain why all models have limitations.
Explanation:
The limitations of model based on Experimental design and parameter
All models have limitations because they simplify complex real-world phenomena, omitting certain details or factors to make them manageable and understandable.
Limitations of modelsAll models have limitations because they are simplified representations of complex systems or phenomena. To make models more manageable and understandable, certain details, variables, or interactions must be excluded.
This simplification can lead to discrepancies between the model and reality, limiting its accuracy and applicability. Additionally, models are often based on existing knowledge, which may be incomplete or subject to change.
As a result, models serve as valuable tools for understanding and prediction but should be used with caution, acknowledging their inherent simplifications and potential shortcomings when applied to real-world scenarios.

Answer:
(b) numbers and (d) units
Explanation:
To measure any quantity, numbers and units are required. It can be understood with an example.
We measure a length of a piece of wood as 5 cm. In this case 5 is a number and centimeters or cm is a unit in which we measure its length. It means for any measurement, number and units are important elements that are required to make sense.

If a liquid has a volume of 5800 mL and you need the mass in Liters, will the number appear to
become smaller or larger?
Answer:
The number will appear to become smaller (from 5800 mL to 5.8 L).
Explanation:
The conversion of milliliters to liters is the following:
1 L = 1000 mL
Hence, the volume of 5800 mL to L is:
[tex] V = 5800 mL*\frac{1 L}{1000 mL} = 5.8 L [/tex]
Therefore, the number will appear to become smaller (from 5800 mL to 5.8 L).
