Answer:
58.8 W
Explanation:
Power = work / time
P = W / t
P = mgh / t
P = (5.00 kg) (9.8 m/s²) (3.00 m) / (2.50 s)
P = 58.8 W
Answer:
Since this is old, im just gonna get these points, don't wan't them to go to waste lm.ao
Explanation:
Answer:
A capacitor
Explanation:
Because it can store electric energy when disconnected from its charging circuit. Commonly used in electronic devices to maintain power supply while batteries change.
Hope this helps! :)
Answer:
"2Ω" is the net resistance in the circuit.
Explanation:
The given resistors are:
R1 = 3Ω
R2 = 6Ω
The net resistance will be:
⇒ ![\frac{1}{R_{net}} =\frac{1}{R_1} +\frac{1}{R_2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Bnet%7D%7D%20%3D%5Cfrac%7B1%7D%7BR_1%7D%20%2B%5Cfrac%7B1%7D%7BR_2%7D)
On substituting the values, we get
⇒ ![\frac{1}{R_{net}} =\frac{1}{3} +\frac{1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Bnet%7D%7D%20%3D%5Cfrac%7B1%7D%7B3%7D%20%2B%5Cfrac%7B1%7D%7B6%7D)
On taking L.C.M, we get
⇒ ![\frac{1}{R_{net}} =\frac{2+1}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Bnet%7D%7D%20%3D%5Cfrac%7B2%2B1%7D%7B6%7D)
⇒ ![\frac{1}{R_{net}} =\frac{3}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Bnet%7D%7D%20%3D%5Cfrac%7B3%7D%7B6%7D)
⇒ ![\frac{1}{R_{net}} =\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7BR_%7Bnet%7D%7D%20%3D%5Cfrac%7B1%7D%7B2%7D)
On applying cross-multiplication, we get
⇒ ![R_{net}=2 \Omega](https://tex.z-dn.net/?f=R_%7Bnet%7D%3D2%20%5COmega)
