We don't have enough information in the picture to answer that question.
The disembodied right hand could just as well grab the wire in the other direction, with the thumb pointing to the right.
Maybe if we knew WHY the hand is holding the wire in this direction, and what other electrical phenomenon may be involved, we might be able to say something about the current in the wire.
(Actually, we don't even know if it's a wire. It might be a soda straw, a coat hanger, or a pool cue.)
Answer:
λ = 3.4 × 10^18m
Explanation:using Rydberg equation:
1/λ = RH •Z^2[ (1/n1) - (1/n2) ]
RH = Rydberg constant = 2.18x 10^-18j)
n1 and n2 = energy levels (n2 >n1)
Z = atomic number = 4
Substitute
1/λ = 2.18x 10^-18• [ (1/3) - (1/5) }
λ = 3.4 × 10^18m
Answer:
0.05 V/m
Explanation:
V = Potential difference that is possible for the dolphin to detect = 0.5 mV
d = Distance between electrodes = 1 cm
Electric field strength is given by
The corresponding electric field strength is 0.05 V/m
A concave mirror is curved inward in the middle, more
like a cave. Because the mirror is curved inward, the angle of the light
surface can be focused similar to that of the camera. They can form real images
that are projected out in front of the mirror at the place where light focuses.
When the object is located at the center of the curvature the image formed will
also be at the curvature. The image will be inverted and the magnification
value is equal to 1 which will become a real image because the ray of light
converges at the location of the formed image.
Answer:
The total energy is 
Explanation:
From the question we are told that
The Poynting vector (energy flux ) is 
The length of the rectangle is 
The width of the rectangle is 
The time taken is 
The total electromagnetic energy falls on the area is mathematically represented as
Where A is the area of the rectangle which is mathematically represented as
substituting values
