Answer:
-6C
Explanation:
We are given that
Charge on an object,Q=-8C
Charge on one piece of object=
We have to find the exact charge of the other piece.
Let q be the charge of second piece of object.
By conservation of charge
Initial charge=Final charge
Substitute the values then we get
Hence, the exact charge of the other piece=-6C
The frequency that the submarine detects a frequency f' as described by Equation 17.19.
Explanation :
(a) Using the Doppler Shift formula, we can determine the frequency of the sonar signal that the crewman in submarine B heard:
Hence, the frequecy of that the submarine detects a frequency f' as described by Equation 17.19.
<h3>
What do you mean by Frequency?</h3>
A frequency is the quantity of waves produced each second.
A measure of frequency is the number of times in a second that an alternating current (AC) changes from positive to negative. Direct currents do not experience this switching (DC). Hertz is used to measure frequency (Hz) The period is the length of time it takes for an AC current to start at zero, change from positive to negative, and then return to zero (i.e., the length of time it takes to complete one cycle), while the frequency is the reciprocal of the period. In contrast to low frequency, which has fewer waves per second but a longer period, high frequency refers to the number of waves per second and the length of the period.

Answer:
It's C because if you were trying to put it at rest that means you would put it on a Balanced surfest
The correct answer to the question is: A) Parallel circuits.
EXPLANATION:
There are normally two types connection of circuit elements which are preferred for connection of electrical appliances.
Most of the circuits in home are connected to each other in a parallel way.
We know that the potential remains constant at every circuit elements for parallel connection. The potential drop across each circuit element will be different for series connection.
Due to the parallel connection, each circuit elements can be switched on or off separately.
Hence, most of the electrical circuits in home are connected in parallel way.
