Answer:
Explanation:
Not really sure what you're trying to do. You propagate uncertainties for indirect measurements, as in when you calculate a value from other values.
What you have here is a series of values of direct measurements it seems.
Anyway, for error bars will have a width of 2 times the uncertainty reported.
For example on the first one
373.67 +/- 15.444
You would have an error bar with a width of 2 * 15.444 = 30.888. This bar would be centered at 373.677. The lowest point of the error bar would be at 358.233 and the highest point at 389.121.
You also mentioned a scatter plot, but scatter plots are 2D at least. Are these measurements associated to something else like time? You need 2 coordinates for each point in a scatter plot.
Answer:
4
Explanation:
you have to divide the velocity by time so 40 divided by 10 and the answer should be 4
Answer: c) the sun is the most massive object; gravitational attraction is related to mass.
Explanation:
Gravitational pull exists between any two objects having mass.
where symbols have their usual meaning.
All the planets including Earth revolve around the Sun because its the most massive object in the neighborhood and thus has high gravitational pull. This gravitational pull of Sun keeps the Earth in its orbit around it.
Hence, the correct answer is earth orbit the sun rather than any other body in the solar system because c) the sun is the most massive object; gravitational attraction is related to mass.
Energy transformations is a process of an energy form transforming into a new form of energy. Like thermal energy, mechanical, etc. An example; when we eat; it turns from chemical energy to mechanical or electrical to heat. Like a plug and to activate a toaster.
