Answer:
magnitude of the resultant of forces is 11.45 N
Explanation:
given data
force F1 = 6N
force F2 = 8N
angle = 240°
solution
we get here resultant force that is express as
F(r) = ..............1
put here value and we get
F(r) =
F(r) = 11.45 N
so magnitude of the resultant of forces is 11.45 N
Answer:
por el Principio de Homogeneidad Dimensional y el uso de operaciones de adición y sustracción.
Explanation:
Por el Principio de Homogeneidad Dimensional, A, B, C y D deben tener las mismas magnitudes físicas para la realización de operaciones de adición y sustracción. Es decir:
, donde
The question is incomplete. The complete question is :
In a certain underdamped RLC circuit, the voltage across the capacitor decreases in one cycle from 5.0 V to 3.8 V. The period of the oscillations is 1.2 microseconds (1.2*10^-6). What is Q?
Solution :
The underdamped RLC circuit
We know in one time period, v = 2v, at t = T,
so,
Now, Q value
∴
= 11.45
