Answer:

Explanation:

Voltaje, tensión, corriente, resistencia, etc. son términos por diferentes investigadores (Danusso y Dupré 1987,

de un lenguaje común con el que todos estamos familia- Buchweitz y Moreira 1987, Dupin y Johsua 1987, Gauld

rizados al utilizarlos para referirnos al funcionamiento 1988, Varela, Manrique y Favieres 1988, Acevedo 1989,

de una gran cantidad de aparatos eléctricos y electróni- Andrés 1990, Licht y Thijs 1990). Las principales caraccos de nuestro entorno cotidiano. terísticas de las interpretaciones de los estudiantes sobre

los circuitos eléctricos que han destacado los investigadores

Las ideas básicas de electricidad son presentadas a los son:

estudiantes en los cursos de física del bachillerato, frecuentemente acompañadas de experimentos sencillos a) La idea de que la bombilla consume o atenúa la

con baterías y bombillas. Como consecuencia, muchos comente que circula por ella. Cuando se colocan varias

estudiantes de bachillerato, y todavía más los de universidad, bombillas en serie, los estudiantes predicen que la bombilla

son capaces, a veces, de resolver complicados circuitos más cercana al punto de donde «sale» la corriente brillará

con mallas eléctricas y de realizar montajes eléctricos con mayor intensidad que las otras, ya que la corriente se

relativamente sofisticados.

A lamp draws a current of 0.50 A when it is connected to a 120 V source? What is the resistance of the lamp?
emmainna [20.7K]
Given,
Current (I) = 0.50A
Voltage (V) = 120 volts
Resistance (R) =?
We know that:-
Voltage (V) = Current (I) x Resistance (R)
→Resistance (R) = Voltage (V) / Current (I)
= 120/0.50
= 24Ω
∴ Resistance (R) = 24Ω

A particle is moving along a circular path of 2-m radius such that its position as a function of time is given by u = (5t 2) rad
OverLord2011 [107]

Answer:

Explanation:

Given

radius of  path r=2\ m

Velocity of Particle \theta =5t^2 rad

where t=time in seconds

angular velocity of particle is given by

\omega =\frac{\mathrm{d} \theta }{\mathrm{d} t}

\omega =2\times 5t=10\cdot t

And angular acceleration is given by

\alpha =\frac{\mathrm{d} \omega }{\mathrm{d} t}

\alpha =10 rad/s^2

tangential acceleration is a_t=\alpha \times r

a_t=10\times 2=20\ m/s^2

Centripetal acceleration a_c=\omega ^2\times r

a_c=(10t)^2\times 2=200t^2

net acceleration is sum of tangential and centripetal force at any time t is given by

a_{net}=\sqrt{(a_c)^2+(a_t)^2}

a_{net}=\sqrt{(200t)^2+(20)^2}

a_{net}=20\sqrt{(10t)^2+1}\ m/s
