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.
Yes, that's correct. That's a big part of the reason why
the soap floats in water and the sponge sinks in it.
Carbon dioxide is a compound (CO2). The other are just considered molecules since they are bonded to themselves. Lithium (Li) is an element since it's on its own and hasn't formed a bond yet.
Answer:
Acceleration = 311.2 Km/hr²
Explanation:
Given: Radius of the Orbit r= 3.56 × 10⁶ km
Period of the orbit = 28 days = 672 hrs
Sol: We have Fc = MV²/r
⇒M ac = MV²/r
⇒ac = V²/r
First we have to Speed V so for this we have to find the circumference ( distance covered by the moon in one orbit)
⇒ Circumference= 2 π r
= 2 × 3.13149 × 3.56 × 10⁶ km
= 22,368,139.69 Km
Now Speed = Distance /time
Speed = 22,368,139.69 Km / 672 hrs
Speed V = 33,285.92 Km/Hr
Now
ac = V²/r = (33,285.92 Km/hrs)² / 3.56 × 10⁶ km
ac = 311.2 Km/hr²
When the magnet is placed on the glass, it is attracted to the iron filings. The pattern of the iron filings shows that the lines of force that make up the magnetic field of the magnet. Also, The lines of force of north and south poles attract each other whereas those of two north poles fend off each other.
