Answer:
a wave with a time period of 2 seconds has a frequency of 1 ÷ 2 = 0.5 Hz. A sound wave has a time period of 0.0001 seconds.
Explanation:
As we know, resistance is the ratio of voltage used and current flowing through the circuit. So,
<h3>R = V/I</h3>
By error calculation
<h3>∆R/R = [(∆V/V)100] + [(∆I/I)100]</h3>
V = 100 ± 6% V
I = 10 ± 0.2% A
∆R/R= (5/100)×100 + (0.2/10)×100
∆R/R=5+2=7%
<h2>So, percentage error in resistance (R) = ± 7%.</h2>
4.8 km because if u add the other bonus if speed and multiply you check the 48 taking off a decimal point
The voltage released because the charges in the current dropped electric potential energy; this energy loss occured due to the resistance of the metal strips.
<u>Explanation:</u>
- Current flows from huge voltage (high potential) to base voltage (low potential).
- So the end of the strip wherever the current goes at a higher voltage than the end of the strip where the current leaves.
- The voltage released because the charges in the current dropped electric potential energy; this energy loss occured due to the resistance of the metal strips.
- The electric potential energy converted into thermal energy, heating the strips.
