Answer:
An open circuit does not go on for an infinite time, but the closed circuit does.
Explanation:
Answer:
v = 315 m/s
Explanation:
given,
length of the string = 64.3 cm
frequency at fundamental mode = 245 Hz
speed of sound = 345 m/s
speed of the transverse waves = ?
here
wavelength = twice length of string
λ = 2 L
λ = 2 × 64.3
λ = 128.6 cm = 1.286 m
using formula
v = ν λ
v = 245 × 1.286
v = 315.07 m/s
Hence, the speed of the transverse wave on the string will be equal to v = 315 m/s
Answer: 3 meters
Explanation:
If you were to use a 3 line answer then it would look like this:
d = W/F
d = 3000/1000
d = 3 meters
Answer:
The poles of the magnetic field generated around the armature are attracted to the opposite poles of the permanent magnet. As the opposite poles align, the commutator reverses the current direction so like poles are aligned and the armature continues to spin.
Explanation:
Explanation:
PRIMERO HACES EL RECUENTO DEL TIEMPO Y LO CONVIERTES EN
SEGUNDOS Y ENTONCES
<em>t</em> = 227 s 
= 227 S - 38 s = 189 s
= 38 s
LUEGO USANDO LA ECUACIÓN DE GALILEO GALILEI SSUPONIENDO
QUE EL MOVIL VIAJA A VELOCIDAD CONSTANTE
<em>v</em> = 3.50 m/189 s = 0.0185 m/s
PARA LA DISTANCIA NTRE B Y C
= 0.0185 m/S( 38 s) = 0.703 m
LA HORA EN QUE EL MOVIL PASA POR A ES
11:43:15 - 38 s - 189 s = 11:39:29
