The answer is 15 kilometers in 20 minutes.
Answer:
Explanation:
a )
current in the wire = potential diff / resistance
= 23 / (15 x 10⁻³ )
= 1.533 x 10³ A .
b )
For resistance of a wire , the formula is
R = ρ L / S where ρ is specific resistance , L is length and S is cross sectional area of wire
putting the given values
15 x 10⁻³ = 4ρ / π x .003²
ρ = 106 x 10⁻⁹ ohm. m
= 10.6 x 10⁻⁸ ohm m
The metal wire appears to be platinum .
Net force acting on mass = 20 - 15 = 5N. ( subtracted cuz friction always opposes the motion i.e it always acts in direction opposite to the motion of the object). According to Newton's 2nd law of motion, F(net) = ma. a =F (net) / m = 5/10 = 0.5 m/s^2. Hope it helps :)
Answer:
a. 475.14 Hz
b. 1959 Hz
c. 2341.53 Hz , 3053.34 Hz
Explanation:
a. smallest use the capacitive 4.2 uF + 6.0 uF = 10.2uF replacing:
b. second smallest use the capacitive 6 uF so:
c. second largest and largest oscillation first combination so:
Use 4.2 uF
And finally largest oscillation cap in serie so:
