A single strain gage has a nominal resistance of 120 ohm. For a quarter bridge with 120 ohm fixed resistors, strain gauge factor

natita [175]

Answer:

Output voltage is 1.507 mV

Solution:

As per the question:

Nominal resistance, R = $120\Omega$

Fixed resistance, R = $120\Omega$

Gauge Factor, G.F = 2.01

Supply Voltage, $V_{s} = 3\ V$

Strain, $\epsilon = 1000\times 10^{-6}\ strain$

Now,

To calculate the output voltage, $V_{o}$ :

WE know that strain is given by:

$\epsilon = \frac{(R + R')^{2}V_{o}}{RR'V_{s}\times G.F}$

Thus

$V_{o} = \frac{RR'V_{s}\epsilon \times G.F}{(R + R')^{2}}$

Now, substituting the suitable values in the above eqn:

$V_{o} = \frac{120\times 120\times 3\times 1000\times 10^{-6}\times 2.01}{(120 + 120)^{2}}$

$V_{o} = 1.507\ mV$

A car traveling at 40 m/s starts to decelerate steadily. It comes to a complete stop in 5 seconds. What is its acceleration? m/s

SCORPION-xisa [38]

Acceleration =

   (change of speed) / (time for the change).

Change of speed = (speed at the end) - (speed at the beginning)

      =    ( zero ) - (40 m/s)

   = -40 m/s .

Acceleration = (-40 m/s) / (5 seconds)

   = -8 m/s² .

Which statement best describes why electrons are typically not included when determining the mass of an atom?

Ede4ka [16]

<span>The protons and neutrons are much more massive than the electrons.
</span>
The electrons are simply too small to really change the mass, so they aren't counted.
