Answer:
The answer to your question is the letter D. 2.5 N
Explanation:
The electrostatic force is the same in both directions,
If the electrostatic force on B due to A is 2.5 N, the magnitude of the electrostatic force on A due to B must be 2.5N.
Maybe the direction is different but the magnitude is the same.
Answer:
Explanation:
The velocity is 340, but the distance is not. Here's how you do this:
You need to find out the velocity of the that sound in that temp which has a formula of
v = 331.5 + .606T where T is the temp in Celcius. Filling in and using the correct number of sig dig:
v = 331.5 + .606(20) and
v = 331.5 + 10 and
v = 340 m/s. Now we need to use that in d = vt:
d = 340(2.00) so
d = 680 m
This is because AC is easier to transform from a higher voltage to another, lower voltage, using transformers. High voltage means less <span>resistive losses in the power lines during transmission. This is why power is transmitted at many hundreds of thousands of volts and is only transformed into 110V or 220V near the consumers. </span>
