Answer:
Explanation:
k = Boltzmann constant =
r = Radius of gas molecule =
t = Temperature = 300 K
P = Pressure
Volume of gas per molecule is given by
From the ideal gas law we have
The pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior is
t = total time taken by sound to go down the well and then come back = 2 sec
d = depth of the well
D = total distance traveled by the sound
total distance traveled by sound is given as
total distance traveled = distance traveled going down + distance traveled going up
D = d + d
D = 2 d eq-1
v = speed of sound = 343 m/s
we know that distance traveled is given as
total distance traveled = speed of sound x total time
D = v t
using eq-1
2 d = v t
2 d = (343) (2)
dividing both side by 2
d = 343 x 2/2
d = 343 m
hence surface of water is 343 m deep
When attempting to measure current flow, the ammeter should be inserted directly into the circuit so as to force each and every charge through the meter itself. This statement is False.
<h3>What is ammeter?</h3>
An ammeter is a device used to measure the current.
Ammeter is the necessary component must be inserted to the circuit. An ammeter is placed in series in the circuit in order to add its resistance. Ammeter doesn't force any charge to pass through it. It just measure the amount of charge passing through it.
Thus, the statement when attempting to measure current flow, the ammeter should be inserted directly into the circuit so as to force each and every charge through the meter itself is False.
