Answer:
V = 6.55*10^{-6} v
Explanation:
The number density can be determined by using below formula:

where,
B is uniform magnetic field 0.74
i is current 18 A
V is hall potential difference
l is thickness 150 MICRO METER
e is electron charge 1.6 *10^{-19} C
therefore V can be determined as


V = 6.55*10^{-6} v
Here is the answer. The external cause code for a passenger that is involved in a MVA that lost control on the highway and hits a guardrail is E815. Your fifth digit is a 1 for a motor vehicle
passenger. You would use an additional E code when a place of occurrence (example, home or parking lot) is
documented. In this case, the location is documented as the highway. Hope this helps.

The correct choice is ❝ A ❞

It's False. Because it's electromagnet NOT circuit. I'd go with False if I were youSorry if you get it wrong. Hope this helps.
