Answer:
the inductive reactance of the coil is 1335.35 Ω
Explanation:
Given;
inductance of the coil, L = 250 mH = 0.25 H
effective current through the coil, I = 5 mA
frequency of the coil, f = 850 Hz
The inductive reactance of the coil is calculated as;

Therefore, the inductive reactance of the coil is 1335.35 Ω
The centripetal force, Fc, is calculated through the equation,
Fc = mv²/r
where m is the mass,v is the velocity, and r is the radius.
Substituting the known values,
Fc = (112 kg)(8.9 m/s)² / (15.5 m)
= 572.36 N
Therefore, the centripetal force of the bicyclist is approximately 572.36 N.
Answer:
(A) v = 14.8m/s
Explanation:
(A) V = sqrt(k/m) × A = sqrt(22/0.1) × 0.29 =14.8m/s.
Answer:
Explanation:
Let t be the final temp
temp. drop of nickel=147.4-t
temp. gain by water=t-29.9
in equilibrium
Heat lost=Heat gained
58.7×0.443×(147.4-t)=184×4.18×(t-29.9)
58.7×0.443×147.4-58.7×0.443×t=184×4.18×t-184×4.18×29.9
3833.00434 -26.0041 t=769.12t-22996.688
(769.12 +26.0041)t= ?
find t
