Answer:
The momentum principle tells us that impulse transfers momentum to an object. If an object has 2 kg m/s of momentum, a 1 kg m/s impulse delivered to the object increases its momentum to 3 kg m/s. That is, pfx = pix + Jx. Just as we did with energy, we can represent this “momentum accounting” with a momentum bar chart.
Answer:
Range of R is from 4.81MΩ to 36.54 MΩ
Explanation:
Capacitance(C) = 0.520 µF = 0.52 x 10^(-6) F
Time constant = from 2.5 to 19 seconds
In RC circuits, time constant is;
r = RC
Where R is the range (in MΩ)
And r is time constant
Thus,
R = r/c
So minimum range will be at 2.5seconds.
Thus; Rmin = 2.5/(0.52 x 10^(-6)) = 4.81 x 10^(6) Ω = 4.81MΩ
Rmax = 19/(0.52 x 10^(-6)) = 36.54 x 10^(6) Ω = 36.54 MΩ
Answer:
D. All of the above
Explanation:
Global warming may cause all of the given choices.
Global warming is the rise in surface temperature. This is due to the trapping of heat within the earth surface.
It is as a result of huge amount of greenhouse gases within our atmosphere. They typically permit short wave radiations to escape and they do not allow short wave radiation to pass through. This in turn produces heat.
- The heat can melt polar ices and glaciers.
- This in turn will cause sea levels to rise.
- Also, the ocean temperature will generally increase due to this.
Answer:
direction
Explanation:
because particles surround the bell, so when the bell vibrates, it causes particles surrounding it to vibrate back and forth vigorously. as these particles vibrate they collide with the neighbouring particles, passing on the energy.
hope this is what you are asking, if not please report it so that someone else gets to try it.
C) They are made of tiny droplets of water.
