Answer:
Electric and magnetic field waves are oriented at 90 degree angles relative to each other.
Explanation:
Answer:
false
Explanation:
the answer is false bc for a non-polar bond to form the electrons are shared equally...
<h2>
Mercury, Neptune, and Jupiter </h2>
Explanation:
- Mercury has the largest semimajor axis that is 5.791 x 107 in km.
- Mercury is the planet with the fastest speed, which has an average orbital speed around the sun for about 47.87 km/s.
- Neptune has the longest orbital speed around the sun of any planet in the Solar System which is equivalent to 164.8 years (or 60,182 Earth days)
- Jupiter has the largest eccentricity.
Hence, the answer is Mercury, Neptune, and Jupiter respectively.
Answer:
a) 4.9*10^-6
b) 5.71*10^-15
Explanation:
Given
current, I = 3.8*10^-10A
Diameter, D = 2.5mm
n = 8.49*10^28
The equation for current density and speed drift is
J = I/A = (ne) Vd
A = πD²/4
A = π*0.0025²/4
A = π*6.25*10^-6/4
A = 4.9*10^-6
Now,
J = I/A
J = 3.8*10^-10/4.9*10^-6
J = 7.76*10^-5
Electron drift speed is
J = (ne) Vd
Vd = J/(ne)
Vd = 7.76*10^-5/(8.49*10^28)*(1.60*10^-19)
Vd = 7.76*10^-5/1.3584*10^10
Vd = 5.71*10^-15
Therefore, the current density and speed drift are 4.9*10^-6
And 5.71*10^-15 respectively
