Answer:
0.0360531138247 V/m
Explanation:
= Resistivity of gold =
(General value)
I = Current = 940 mA
d = Diameter = 0.9 mm
A = Area = 
E = Electric field
Resistivity is given by

The electric field in the wire is 0.0360531138247 V/m
To solve this exercise we need the concept of Kinetic Energy and its respective change: Initial and final kinetic energy.
Let's start considering that the angular velocity is given by,

Where,
V = linear speed
R = the radius
In the case of the initial kinetic energy:

Where I is the moment of inertia previously defined.

In the case of the final kinetic energy, we have to,


For conservation of Energy we have, that
, then (canceling the mass and the radius)





The answer would be A, since at that position the Earth is fully/partially being engulfed in a shadow cast by the moon from the sun’s rays.
Hope this helps!
Answer:
The distance from harvest mouse to the leaf is 4.74 m.
Explanation:
Given that,
Intensity = -10 dB
Distance = 1.5 m
We need to calculate the power of intensity
Using formula of power of intensity


Put the value into the formula


We need to calculate the minimum intensity level
Using formula of minimum intensity





We need to calculate the area
Using formula of intensity


Put the value into the formula


We need to calculate the distance
Using formula of area

Put the value into the formula




Hence, The distance from harvest mouse to the leaf is 4.74 m.
