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
Equation
KE. + PE. = KE<em>f </em>+ PE<em>f</em>
<em>By the time the Rocket reaches an infinete distance the </em><em>KE</em><em>f and </em><em>PE</em><em>f power would be down to zero so then the equation will become </em><em>KE. + PE. = 0 </em>
<em>Cant explain much because dont know if this anserw recwires any speical things to solve it</em>
Answer:
Explanation:
La aceleración es directamente proporcional a la magnitud de la fuerza resultante. Así, si se duplica la fuerza, la aceleración se duplica; si se triplica la fuerza, se triplica la aceleración. Por otro lado, la aceleración es inversamente proporcional a la masa del cuerpo que se acelera.
Answer:
The maximum electric field strength is
Explanation:
Substitute 4.0 cm for D
r = D / 2
r = 4 / 2 = 2cm
= 2 × 10⁻²m
Now, according to the question, the expression for the magnetic field is as follows:
B = 10T + 2T sin(2π(10Hz) t )
Now, calculate
Therefore, the electric field expression is as follows:
Substitute 0 for t in the above equation
Now substitute 1.5 cm for r in the above equation
The maximum electric field strength is
