Answer:
4.38 × 10⁻³ A
0.395mΩ
452 µΩ
Explanation:
(a)the current in each strand is = the total current/ number of strand
0.876/ 200 = 4.38 × 10⁻³ A
(b) potential difference = IR
the total resistance = 2.26 µΩ × 0.876
= 0.395mΩ
c) resistance of the cable = 2.26 µΩ × 200
=452 µΩ
Answer:
D. The acceleration is downward at all points in the motion
Explanation:
:D
I believe is A) Inner core
<span>where u is in radians.
The linear velocity of the point is tangent to the circle; the
point’s linear speed v is given by
v vr (radian measure), (10-18)
wherev is the angular speed (in radians per second) of the body.
The linear acceleration of the point has both tangential and
radial components.The tangential component is
at ar (radian measure), (10-22)
where a is the magnitude of the angular acceleration (in radians
per second-squared) of the body.The radial component of is
(radian measure). (10-23)
If the point moves in uniform circular motion, the period T of
the motion for the point and the body is
(radian measure).</span>
