Answer:
Y = 4.775 x 10⁹ Pa = 4.775 GPa
Explanation:
First, we calculate the stress on the rod:

Now, we calculate the strain:

Now, we will calculate the Young's Modulus (Y):

<u>Y = 4.775 x 10⁹ Pa = 4.775 GPa</u>
Answer:
515.22 m/s
Explanation:
Formula for root mean square velocity is SQRT (3RT/M)
Where,
R = Rydberg's constant = 8.314 Kg. m²/ s². K. mol
T = Temperature in Kelvin
M = Molar mass in Kg/mol
First calculate molar mass,
As nitrogen is diatomic molecule,
Its molar mass is
M = 2(14) = 28 g/mol
Convert unit into Kg/mol
28 g/mol x 1 Kg/1000g = 2.8x10¯² Kg/mol
Convert temperature into kelvin
T = 25 + 273 = 298K
Put all values in formula
Vrms = SQRT (3RT/M)
Vrms = SQRT (3x8.314x298/2.8x10¯²)
Vrms = SQRT (265454. 14)
Vrms = 515.22 m/s
Answer:
I don't really know much about the whole stars thing, but I've written a lot of paragraphs in science
Explanation:
Remember:
- A paragraph should be in CER formation: Claim (hypothesis/discovery), Evidence, and Reasoning
- Your reasoning should never start with I believe or I think, your reasoning and evidence are 100% fact based
- The actual hypothesis should only be 1-2 sentences and be straight to the point
Include:
- for your hypothesis, keywords relating to your subject, I'm assuming for your topic you should include things like marking, telescope, stars, etc.
- why you believe your hypothesis is true
- so use prior knowledge to justify your hypothesis
Answer:
A charged battery that is NOT part of a circuit is an example of potential energy.
