Explanation:
According to the figure,
![\vec{p} = q\vec{d}](https://tex.z-dn.net/?f=%5Cvec%7Bp%7D%20%3D%20q%5Cvec%7Bd%7D)
Formula to calculate net dipole moment is as follows.
![\vec{p_{net}} = 2P Cos 52^{o}\hat{i} + (0)\hat{j}](https://tex.z-dn.net/?f=%5Cvec%7Bp_%7Bnet%7D%7D%20%3D%202P%20Cos%2052%5E%7Bo%7D%5Chat%7Bi%7D%20%2B%20%280%29%5Chat%7Bj%7D)
![\vec{p_{net}} = 2qd Cos 52^{o}\hat{i}](https://tex.z-dn.net/?f=%5Cvec%7Bp_%7Bnet%7D%7D%20%3D%202qd%20Cos%2052%5E%7Bo%7D%5Chat%7Bi%7D)
= ![2 \times 1.6 \times 10^{-19} \times 0.958 \times 10^{-10} \times Cos 52^{o}\hat{i}](https://tex.z-dn.net/?f=2%20%5Ctimes%201.6%20%5Ctimes%2010%5E%7B-19%7D%20%5Ctimes%200.958%20%5Ctimes%2010%5E%7B-10%7D%20%5Ctimes%20Cos%2052%5E%7Bo%7D%5Chat%7Bi%7D)
=
C-m
Therefore, we can conclude that the net dipole moment for given water molecule is
C-m.
Answer:
Total displacement will be 1120 meters.
Explanation:
To calculate displacement from the velocity, need to take integral of velocity for a one time period.
![x=\int\limits^7_{-1} {t^3-15*t^2} \, dt\\x=\int\limits^7_{-1} {t^3} \, dt-\int\limits^7_{-1} {15*t^2} \, dt\\x=600-1720\\x=-1120](https://tex.z-dn.net/?f=x%3D%5Cint%5Climits%5E7_%7B-1%7D%20%7Bt%5E3-15%2At%5E2%7D%20%5C%2C%20dt%5C%5Cx%3D%5Cint%5Climits%5E7_%7B-1%7D%20%7Bt%5E3%7D%20%5C%2C%20dt-%5Cint%5Climits%5E7_%7B-1%7D%20%7B15%2At%5E2%7D%20%5C%2C%20dt%5C%5Cx%3D600-1720%5C%5Cx%3D-1120)
The total displacement is 1120 meter in negative way.
Answer:
D,E,F
Explanation:
d. Earth's geographic north pole is actually a magnetic south pole.
e. The south poles of two bar magnets will repel each other.
f. The north pole of a bar magnet will attract the south pole of another bar magnet.
In a magnetic field like poles repel and unlike poles attract each other. The like poles which is south to south or north to north repel each other and the unlike poles which is north to south or south to north attract each other which makes E and F correct.
A is correct because compasses points to the North Pole when places in the Southern Hemisphere.
Answer:
E = 10t^2e^-10t Joules
Explanation:
Given that the current through a 0.2-H inductor is i(t) = 10te–5t A.
The energy E stored in the inductor can be expressed as
E = 1/2Ll^2
Substitutes the inductor L and the current I into the formula
E = 1/2 × 0.2 × ( 10te^-5t )^2
E = 0.1 × 100t^2e^-10t
E = 10t^2e^-10t Joules
Therefore, the energy stored in the inductor is 10t^2e^-10t Joules
