Answer:
Output voltage is 1.507 mV
Solution:
As per the question:
Nominal resistance, R = 
Fixed resistance, R = 
Gauge Factor, G.F = 2.01
Supply Voltage, 
Strain, 
Now,
To calculate the output voltage,
:
WE know that strain is given by:

Thus

Now, substituting the suitable values in the above eqn:


Answer:
you can't see your back because your neck can only move in fixed direction
Answer:
Magnetic flux, 
Explanation:
It is given that,
Magnitude of the magnetic field, B = 0.078 T
Radius of circular loop, r = 0.1 m
The field is oriented at an angle of θ = 25° with respect to the normal to the surface. The magnetic flux through the surface is given by :



or

So, the magnitude of magnetic flux through the surface is
. Hence, this is the required solution.
Answer:
length of a quarter wavelength antenna for transmitter elf waves are zero
Explanation:
Find the length of a quarter wavelength antenna for transmitter elf waves
Given information
frequency (ELF waves) → 77Hz
Speed of light → 3
m/s

where
→ wavelength of the antenna
f → frequency of the ELF waves
→ speed of light
so rewrite the equation in
from

Substitute
= 
Substitute 75Hz = f

m
since we get this value,but this size of antenna mount on submarine is not possible.
so
is zero
