F=ma. So if you have the Force and the Acceleration you can find the mass. m=F/a. So the mass is 25kg
We use the voltage division problem between the load resistance, amplifier output resistance as
.
Here, is the output voltage, is the amplifier voltage, is the load resistance and is the amplifier output resistance.
Therefore,
.
Thus, the amplifier output resistance is .
The battery will be full still a 8v bc of no time comparison
Answer:
Her average speed is 5 miles per hour.
Explanation:
Average speed is the ratio of total distance travelled in particular time.
The park's pond is 0.5 miles around.
She can swim 20 laps, it means she can swim total = 20 × 0.5
= 10 miles.
Time taken by her to complete the track = 2 hour
Now, Average speed =
=
= 5 miles/hour.
the answer is C the wave is moving horizontally as the particles of the rope move up and down.
