Answer:
Explanation:
= 14 km
= 49 km
Intensity of a wave is inversely proportional to distance
So,
The ratio of the intensities is
Answer:
a) emf = 0.01804 V
b) I = 0.03 A
Explanation:
a) The emf is calculated by using the following formula:
A: area of the loop = 0.0820m^2
B: magnitude of the magnetic field
dB/dt: change of the magnetic field, in time: 0.220 T/s
Where ФB is the magnetic flux, the surface vector and magnetic vector are perpendicular between them, and the area A is constant.
You replace the values of A and dB/dt in the equation (1):
b) The current in the loop is:
R: resistance of the loop = 0.600Ω
Answer:
P(abs) = 48 KPa
Explanation:
Given that
Vacuum gauge pressure = 44 KPa
We know that Vacuum gauge pressure is also known as negative gauge pressure .
P(gauge) = - 44 KPa
Atmospheric pressure = 92 KPa
P(atm) = 92 KPa
We know that absolute pressure given as
Absolute pressure = Atmospheric pressure + Gauge pressure
Now by putting the values in the above equation
P(abs) = 92 - 44 KPa
P(abs) = 48 KPa
Therefore the absolute pressure in the chamber will be 48 kPa
