Answer: The magnitude of the force is 5.4N
Explanation:
Answer:
1.6 s
Explanation:
To find the time in which the potential difference of the inductor reaches 24V you use the following formula:
V_o: initial voltage = 60V
R: resistance = 24-Ω
L: inductance = 42H
V_L: final voltage = 24 V
You first use properties of the logarithms to get time t, next, replace the values of the parameter:
hence, after 1.6s the inductor will have a potential difference of 24V
Answer:
El coeficiente de roce estático entre las dos superficies es 0.131.
Explanation:
El coeficiente de roce estático entre dos superficies (), sin unidad, es igual a la fuerza de resistencia (), en newtons, dividida por el peso del cuerpo a mover (), en newtons.
(1)
Donde:
- Masa, en kilogramos.
- Aceleración gravitacional, en metros por segundo al cuadrado.
Si sabemos que , y , entonces el coeficiente de roce estático es:
El coeficiente de roce estático entre las dos superficies es 0.131.
Answer:
F = 0.114 N
Explanation:
a) The magnetic force is given by the equations
F = q v x B = I Lx B
the bold incate vector. This equation can be used in the form of magnitude and find the direction separately with the rule of the right hand
F = i L B sin θ
Where θ is the angle between the direction (L) and the magnetic field, if the two are perpendicular sin 90 = 1
Let's calculate
F = 3.30 0.127 0.272
F = 0.114 N
b) to know the direction of the magnetized field we must know the direction of B and L, but in the problem they tell us that they are perpendicular, but not the direction of each
