A. Reduced greenhouse gas emissions.
It expands due to heat and makes it easier to open the jar.<span />
Gravitational potential energy can be described as m*g*h (mass times gravity times height).
Originally,
15kg * 9.8m/s^2 *0.3 m = 44.1 kg*m^2/s^2 = 44.1 Joules.
After it is moved to a 1m shelf:
15kg * 9.8m/s * 1 = 147 kg*m^2/s^2= 147 Joules.
To find how much energy was added, we subtract final energy from initial energy:
147 J - 44.1 J = 102.9 Joules.
Answer:
Atoms are composed of electrons (charge -1), protons (charge +1), and neutrons (no charge). So in a neutral atom the correct answer is "D".
Given:
L = 1 mH =
H
total Resistance, R = 11 ![\Omega](https://tex.z-dn.net/?f=%5COmega)
current at t = 0 s,
= 2.8 A
Formula used:
![I = I_{o}\times e^-{\frac{R}{L}t}](https://tex.z-dn.net/?f=I%20%3D%20I_%7Bo%7D%5Ctimes%20e%5E-%7B%5Cfrac%7BR%7D%7BL%7Dt%7D)
Solution:
Using the given formula:
current after t = 0.5 ms = ![0.5\times 10^{-3} s](https://tex.z-dn.net/?f=0.5%5Ctimes%2010%5E%7B-3%7D%20s)
for the inductive circuit:
![I = 2.8\times e^-{\frac{11}{1\times 10^{-3}}\times 0.5\times 10^{-3}}](https://tex.z-dn.net/?f=I%20%3D%202.8%5Ctimes%20e%5E-%7B%5Cfrac%7B11%7D%7B1%5Ctimes%2010%5E%7B-3%7D%7D%5Ctimes%200.5%5Ctimes%2010%5E%7B-3%7D%7D)
![I = 2.8\times e^-5.5](https://tex.z-dn.net/?f=I%20%3D%20%20%202.8%5Ctimes%20e%5E-5.5)
I =0.011 A
