Answer:
The electrical flow through the borehole is 353 Nm²/C.
(e) is correct option.
Explanation:
Given that,
Radius = 8.00 cm
Charge = 20.00 μC
radius of drill = 2.00 mm
We need to calculate the electrical flow through the borehole
Using formula of electric flow
Where, q = charge
R = radius of sphere
r = radius of drill
Put the value into the formula
Hence, The electrical flow through the borehole is 353 Nm²/C.
Answer:
147.456077993 Hz
Explanation:
= Frequency of the sonar = 22 kHz
= Velocity of the whale = 4.95 m/s
v = Speed of sound in water = 1482 m/s
The difference in frequency is given by
The difference in frequency is 147.456077993 Hz
Answer:

Explanation:
The density of a substance is an intrinsic property. Intrinsic properties are properties that are characteristic of a material. It does not depend on the amount of substance present.
Since density is an intrinsic or intensive property, If you cut a piece of gold in half, the density of each piece will still be 19.32 g/cm 3 because density does not depend on the size of the gold piece.
