Answer:
The answer is b.) and d.)
Explanation:
The options to reduce the background noise in magneto-medicine are given as follows:
a.) Orienting the heart parallel to the Earth's field
- This will have no significant effect on the measurements.
b.) Taking the difference of two nearby sensor measurements (gradiometer).
-This answer is TRUE.
c.) Placing the heart in a perpendicular fashion to the Earth's magnetic field.
_ This answer also will not have any significant effect on measurements.
d.) Using physical means to shield environmental fields.
- This answer is TRUE.
Answer:
Resistance is the opposing of the flow of current through a conductor.
Answer:
Explanation:
Since there's no external force beside gravity acting on the rod, we can use the law of energy conservation to calculate for the speed of rod center of gravity before hitting the surface.
Also as the rod is uniform and this, its center of gravity is at distance h/2 from the surface.
