Explanation:
It is given that,
Diameter of the circular loop, d = 1.5 cm
Radius of the circular loop, r = 0.0075 m
Magnetic field,
(A) We need to find the current in the loop. The magnetic field in a circular loop is given by :
I = 32.22 A
(b) The magnetic field on a current carrying wire is given by :
r = 0.00238 m
Hence, this is the required solution.
The first P1 power connector to the motherboard have that
was used with the original ATX contained a 20-pin P1 connector.
The 20-pin ATX style connector or the Molex 39-29-9202 is
the industry standard ATX power-supply–to–motherboard main connector. It is utilized
in the SFX form factor or any other ATX-based variations and was first used in
the ATX form factor power supply.
The ATX standard recommends the colors for the wires that
are listed in Table 3.3, however, they could vary from manufacturer to
manufacturer since they are not required for compliance to the specification. The
pins are arranged looking at the back of the connector (from the wire and not
terminal side) as shown in the table since it shows that its orientation if the
connector plugged in was back-probed.
Answer:
Explanation:
In this case we shall calculate rate of change of flux in the coli to calculate induced emf .
Flux through the coil = no of turns x area x magnetic field perpendicular to it
=34 x 2.25 x (3.95 )²x 10⁻⁴ Weber
= 1193.4 x 10⁻⁴Weber
Final flux through the coil after turn by 90°
= 1193.4 x 10⁻⁴ cos 90 ° =0
Change of flux
= 1193.4 x 10⁻⁴ weber.
Time taken = 0.335 s .
Average emf= Rate of change of flux
= change in flux / time
=1193.4 x 10⁻⁴ / .335
= 3562.4 x 10⁻⁴
356.24 x 10⁻³
=356.24 mV.
Current induced = emf induced / resistance
= 356.24/.780
= 456.71 mA.
Answer:
The impulse experienced by the object equals the change in momentum of the object. In equation form, F.t = m. Δv. In a collision, objects experience an impulse; the impulse causes and is equal to the change in momentum.
