We humans are on track to increase the amount of CO2 in the atmosphere so that the concentration in the future more than double
Lapatulllka [165]

Answer:

Rapid increase in the temperature of the earth.

Explanation:

CO2 is known as a greenhouse gas. It is able to trap and retain infrared radiation in the earths atmosphere thereby causing a gradual rise in the temperature of the earth. If this doubled concentration of CO2 is sustained over a long period of time, it will eventually lead to melting of polar ice caps and consequent flooding. Gradually, the earth would be destroyed due to the scorching heat and attendant flood.

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
