How much mass of ice at 0℃ must melt when ∆Q=948000 J of heat energy is added to it?

butalik [34]

<h2>The ice melted is nearly 2.8 kg </h2>

Explanation:

The quantity of heat required to melt the ice can be found by the relation .

ΔQ = m x L

here L is used for the latent heat of fusion .

Its value is 334 J per gram for ice .

Thus m = $\frac{\Delta Q}{L}$ = $\frac{948000}{334}$ = 2836 gram

or = 2.8 kg approx

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:

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

$V_{o} = 1.507\ mV$
