Respuesta:
2 × 10⁴ V
Explicación:
Paso 1: Información provista
- Carga transportada (q): 4 nC
- Trabajo realizado (W): 7 × 10⁻⁵ J
Paso 2: Convertir q a Coulomb
Usaremos el factor de conversión 1 C = 10⁹ nC.
4 nC × 1 C/10⁹ nC = 4 × 10⁻⁹ C
Paso 3: Calcular el potencial eléctrico (V) de la esfera
Usaremos la siguiente fórmula.
V = W/q
V = 7 × 10⁻⁵ J/4 × 10⁻⁹ C = 2 × 10⁴ V
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
Answer:
Total time spend = 48.18 hours (Approx)
Explanation:
Given:
Total distance = 5,300 km
Average speed = 110 km / h
Find:
Total time spend
Computation:
Time = Distance / speed
Total time spend = Total distance / Average speed
Total time spend = 5,300 / 110
Total time spend = 48.18 hours (Approx)
DNA of two species is one of the best evidence to tell us how closely related the two species are.
