A thin metal film of length 1.20 cm, width of 0.300 cm, and thickness of 21.0 micrometers is used to measure the Hall effect. A current of 1.20 A is maintained along the length of the sample. The Hall voltage of 21.8 microVolts is detected across its width, when a magnetic field of 1.20 Tesla is applied normal to the film. Calculate the drift velocity of the charge carriers.

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea

explanation:

98.4 m

explanation:

let s = distance up the plane  

then by conservation of energy  

1/2m(18.3)^2 = mg s sin(10)  

(18.3)^2 = 2g s sin(10)  

s = (18.3)^2/2gsin(10)  

= 98.39564526  

= 98.4 m
