If a display has a dynamic range of 20 dB and the smallest voltage it can handle is 200 mV, then the largest voltage it can hand
DedPeter [7]

Answer:

The largest voltage is 0.02 V.

(d) is correct option.

Explanation:

Given that,

Range = 20 dB

Smallest voltage = 200 mV

We need to calculate the largest voltage

Using formula of voltage gain

G_{dB}=10 log_{10}(\dfrac{V_{out}^2}{V_{in}^{2}})

20 =10 log_{10}(\dfrac{V_{out}^2}{V_{in}^{2}})

2=log_{10}(\dfrac{V_{out}^2}{V_{in}^{2}})

10^2=\dfrac{V_{out}^2}{V_{in}^{2}}

\dfrac{V_{out}}{V_{in}^}=10

V_{in}=\dfrac{V_{out}}{10}

V_{in}=\dfrac{200}{10}

V_{in}=20\ mV

V_{in}=0.02\ V

Hence, The largest voltage is 0.02 V.

Ice of mass 5 g at 0 °C melts to water at 0 °C.
amid [387]

Answer:

Q=1670J

Explanation:

Mass of ice: m=5g=0.005kg

Latent heat: lambda=3.34×10⁵J/kg

Heat received by ice: Q=m×lambda

Q=0.005×3.34×10⁵=5×334=1670J
