If each lightbulb is identical they should have approximately the same resistance therefore the voltage would be split equally so the Voltage over each light bulb would be 3V.

Question 5 (1 point)
Andre45 [30]

The symbol most often used to represent electric current is ' <em>I</em> '.

That's a "capital eye", not a "one".

The unit of measurement of electric current is the Ampere, ' <em>A</em> '.

[Please help :^)]
Serhud [2]

Answer:

the potentail of kinetic and potential energy

Explanation:

first explain the concept of kinetic energy (what it is and what its used for) and give examples (cars, a basketball thrown across a hall, and airplane), and do the same with potential energy (the energy an object stores, example: a streched rubber band)

Determine the minimum angle at which a roadbedshould be banked
poizon [28]

To solve this problem, apply the concepts related to the relationship given between the centripetal Force and the Weight.

The horizontal force component is equivalent to the weight of the car, while the vertical component is linked to the centripetal force exerted on the car, therefore,

T cos\theta = mg \rightarrow T = \frac{mg}{cos\theta}

Tsin\theta = \frac{mv^2}{r} \rightarrow T = \frac{mv^2/r}{sin\theta}

Equating both equation we have that,

\frac{mv^2}{r} = mgtan\theta

tan\theta = \frac{v^2}{rg}

Rearranging to find the angle we have that,

\theta = tan^{-1} (\frac{v^2}{rg})

Our values are given as,

r = 2.00*10^2m

v = 20m/s

\theta = tan^{-1}(\frac{20^2}{(2*10^{2})(9.8)})

\theta = 11.53 \°

Therefore the minimum angle will be 11.53°

4 newtons, 4 amps, 4 joules, 4 watts, 4 ohms, 4 volts<br> what does I=
Ganezh [65]

Answer:

I = 4 amperes

Explanation:

Newton is the unit of force. Hence  4 newton is not the current “I”

Joules is the unit of  energy and hence it do not signify current I

Watt is the unit of power i.e the rate of transfer of energy.  

Ohm is the unit of resistance produces thereby obstructing the flow of current

And Volts is the unit of voltage or potential difference between two ends of an electric circuit. Thus, it is also does not signifies current.

Thus, I = 4 amperes
