If a distance versus time graph is flat, what does that say about the velocity at that time?

Answers

Answer 1

Answer:

In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity). Applying the principle of slope to the graph on the left, one would conclude that the object depicted by the graph is moving with a negative velocity (since the slope is negative ).

Just conversion of units

Explanation:

Mnemonic Device: Kings Hate Dragons Because Dragons Can’t Make Money

(Kilo, Hecto, Deca, Base, Deci, Centi, Milli, Micro)

First one is decaliter which is 10 liters so I convert to liters first 0.0007 liters and then add another 0 to make it in daL so 0.00007

Second is converting from meters to millimeters so 1000mm go into one meter so 3100mm

Same thing for the mass one 0.3kg to ____g well there is 1000g/1kg and then the kg cancel out (this is the safest way to do this) and you get 300 grams

The last one is cm to decimeters not deca and there are 10 centimeters in each decimeters or you could convert to meters and then back again. I would just take the easy out and go with 25.4cm (I think of this one like mm to cm as it is the same ratio and how many times have you used a ruler with both units on it. A 30 cm ruler would be 3 decimeters for the whole 30 cm.

What is the difference between a measurement and an observation?A. Measurements are made with tools; observations are not.B. Observations are biased, while measurements are always unbiased.C. Measurements are compared to a standard; observations are not.D. Observations are only indirect ways of gathering data.

Answers

Answer:

A. Measurements are made with tools; observations are not

Explanation:

Measurement: the assignment of numbers or codes according to prior-set rules.

Observation: data from an individual study subject or sampled unit.

Measurement error: differences between "true" answers and what appears on data collection instruments

Jimmy can travel 550 miles South in 10 hours. Jimmy's velocity is____

Answers

Answer:

The answer is

55 miles/hr

Explanation:

The velocity or speed of an object can be found by using the formula

[tex]velocity \: = \frac{distance}{time} [/tex]

From the question

time taken to travel = 10 hours

distance covered = 550 miles

Substitute the values into the above formula and solve for the velocity

That's

[tex]velocity = \frac{550}{10} [/tex]

We have the final answer as

55 miles/hr

Is it possible to have positive velocity and positive acceleration?

Answers

Explanation:

Yes. For example, when you press the gas pedal in a car, you accelerate in the same direction that you are moving in. So the velocity and acceleration have the same sign.

PLEASE HELP THIS IS DUE TODAY If an element's atomic mass and atomic number are known, what else can be determined? Give an example to demonstrate your understanding.

Answers

If you know an element’s atomic number, you will learn the number of protons and electrons. The atomic number is equal to the number or protons and electrons. You can also find the number of neutrons, by subtracting the atomic mass from the atomic number.

For example, Fluorine’s atomic number is 9, and its atomic mass is 19. So, the number of electrons and protons in fluorine is 9. The number of neutrons the is equal to 19-9. Thus, Fluorine has 10 neutrons.
