Answer:
Explanation:
Time for one dot = 1 /50 = .02 s
Distance between 3 rd and fourth dot is 3 cm and time taken to travel this distance is .02 s
velocity = 3 cm / .02 = 150 cm /s
Distance between 4 th and 5 th dot is 4 cm and time taken to travel this distance is .02 s
velocity = 4 cm / .02 = 200 cm /s
change in velocity = 200 cm/s - 150cm/s = 50 cm /s
Time taken = .02 s
Acceleration = 50 / .02 cm/s²
= 2500 cm/s²
Answer:
The electron dot diagram for magnesium oxide consists of magnesium in Mg2+form, and oxygen showed with 8 valence electrons (dots) with a negative charge of 2.
Answer:
Cost to leave this circuit connected for 24 hours is $ 3.12.
Explanation:
We know that,

f = frequency (60 Hz)
c= capacitor (10 µF =
)

Substitute the given values



Given that, R = 200 Ω





X = 332.31 Ω


Current (I) = 0.361 amps
“Real power” is only consumed in the resistor,



In one hour 26 watt hours are used.
Energy used in 54 hours = 26 × 24 = 624 watt hours
E = 0.624 kilowatt hours
Cost = (5)(0.624) = 3.12
