Answer:12.8°c
Explanation:
specific heat capacity of copper(c)=0.39J*g°c
Mass(m)=20grams
Quantity of heat(Q)=100joules
Temperature rise(@)=?
@=Q/(mxc)
@=100/(20x0.39)
@=100/7.8
@=12.8°c

Answer:
decibel gain is 10 db
Explanation:
given data
voltage v1 = 5 volts
voltage v2 = 15 volts
to find out
decibel gain
solution
we have given that 5 volt voltage that is increase to 15 volts
so
we know here decibel gain formula that is
decibel gain = 20 log(v2/v1) ....................1
put here value of v1 and v2 in equation 1
decibel gain = 20 log(15/5)
decibel gain = 20 log3
decibel gain = 20 × 0.4771
decibel gain = 9.54 db = approx 10 db
so decibel gain is 10 db
Answer:
Explanation:
Let the incident intensity of light on the polariser is Io.
Let the angle of transmission is θ.
According to the law of Malus,
The intensity of light coming out form the polariser is given by
I = IoCos²θ
The mean or the average value of Cos²θ is 1/2
So, the intensity of light coming out from the polariser is
I = Io/2
Thus, the 50% of light is transmitted by the polariser.
