Chlorine belongs to period 3.
A. Air, desk, water. sound travels the slowest through air and the fastest through liquids. solids are somewhere in the middle.
Answer:
ω= 2.095rad/sec
Explanation:
angular frequency(ω)=2πf
F is the frequency
Frequency of an oscillation is the number of cycles completed per second. One oscillation represents 1cycle. Thus for 13 oscillations, the glider completes 13 cycles.
F= 13/39 =
Hz
angular frequency(ω)=2πf
angular frequency(ω)=2π * ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
= 2*
*
rad/sec
ω= 2.095rad/sec
Distance in a minute=<span>0.5 times 30=15 meters
distance in a second</span><span>=15 divided by 60=0.25 meters per second
hope it helps</span>
Answer:
Both the Technician A and Technician B are correct
Explanation:
According to Technician A, an ammeter measures current flow which is correct.
An ammeter is a device which measures the rate of flow of electrons constituting electric current that flows in a circuit.
According to Technician B, Ammeter must be connected in series in an electric circuit which is also correct.
In a circuit with parallel connections, voltage across each branch is same and current is distributed and is different in each branch.
In a series connected circuit, the potential drop, i.e., voltage across each connected element is different while the current in series is the same.
So, in order to measure the correct value of current flowing in the circuit, ammeter must be connected in series in the circuit.
