Answer:
54.17volts
Explanation:
Induced emf in a coil placed in a magnetic field can be expressed as E = N¶/t where
N is the number of turns = 150turns
¶ is the magnetic flux = magnetic field strength (B) × area(A)
¶ = BA
B = 0.65T
A = 1.0m²
t is the time =1.8s
Substituting this value in the formula
E = NBA/t
E = 150×0.65×1.0/1.8
E = 54.17Volts
The induced emf in the coil is 54.17Volts
The three parts of the Earth are Atmosphere, Hydrosphere and Lithosphere.
Atmosphere is the blanket of air that surrounds the earth. It is densest close to the surface and thins out as one moves higher. Atmosphere of Earth contains mainly Nitrogen, followed by Oxygen and small amounts of water vapor, Carbondioxide and other gases.
Lithosphere is the outer most part of the earth's surface. The Earth's crust and the mantle form Lithosphere.
Hydrosphere is the part of the Earth that has water. The Oceans, seas, rivers, lakes and other water bodies constitute the Hydrosphere.
Stratosphere, Mesosphere and Ionosphere are different layers of atmosphere.
Hence, for the study of the Earth, one needs to consider earth to be made of three parts- atmosphere, Lithosphere and Hydrosphere.
Answer:
If the wheelchair is up 7.1 ft. In hight the time of flight should be 0.664 seconds and the distance should be 12.108 ft.
Explanation: I divided the displacement by the time and I used the equation Vx = 20 km/m
I'm not from that school but I can help you.
