Answer:
A
Explanation:
because she wants to practice science and A is the practical option.
Answer:
4.399 Nm
Explanation:
The maximum Torque on a coil is given as,
τ = BNIA...................... Equation 1
Where τ = Maximum torque exerted on the coil, B = Magnetic Field, N = Number of turns, I = Current, A = Area.
Given: N = 45.5 Turns, B = 0.49 T, I = 26.7 mA = 0.0267 A,
A = πr², Where r = radius of the coil, r= 4.85 cm = 0.0485 m
A = 3.14(0.0485)²
A = 7.39×10⁻³ m².
Substitute into equation 1
τ = 45.5×0.49×26.7×7.39×10⁻³
τ = 4.399 Nm
Answer:
Los movimientos verticales o circulación convectiva consisten en un intercambio de lugar entre el aire caliente de las capas bajas y el aire frío de las superiores. Este movimiento se debe a la diferencia de densidades de las distintas masas de aire. Los movimientos horizontales se basan en las diferencias de presión.
Yes. If an object would be vertical, it would most likely have potential energy due to gravity.
Answer:
0.144 J
Explanation:
From the question above,
Total elastic energy of the spring = Kinetic energy of the spring + potential energy of the spring
E' = E.k+Ep...................... Equation 1
Ek = E'-Ep......................... Equation 2
Where E' = total elastic energy, E.k = kinetic energy, E.p = potential energy.
E' = 1/2ke² = 1/2(26.6)(0.12²) = 0.19152 J.
Ep = 1/2ke² = 1/2(26.6)(0.06²)
Ep = 0.04788 J
Therefore,
Ek = 0.19152-0.04788
Ek = 0.144 J
