Answer:
Explanation:
change in flux = no of turns x area of loop x change in magnetic field
= 1 x π 65² x 10⁻⁶ x ( 650 - 350 ) x 10⁻³
= 3.9 x 10⁻³ weber .
rate of change of flux = change of flux / time
= 3.9 x 10⁻³ / .10
= 39 x 10⁻³ V
= 39 mV .
Since the magnetic flux is directed outside page and it is increasing , induced current will be clockwise so that magnetic field is produced in opposite direction to reduce it , as per Lenz's law.
The formula used to find potential energy is <em>P.E. = M * G * H</em> (P.E. is potential energy, M is mass, G is gravitational pull, and H is height). So the answer to your question is <em>5 * 9.8 * 2</em>, which equals 98.
Answer:
For cast iron we have
For copper
For Lead
For Zinc
Explanation:
As we know that final speed of the block is calculated by work energy theorem
now we have
now we have
For cast iron we have
For copper
For Lead
For Zinc
False because currents do not flow easily through insulators. If it only said conductors, then it would be true.
Changes. :) I think... Whats your question
?
