Answer:
C
Explanation:
From the question we are told that a vector on the x and y plane face their negative axis
Generally in the x and y plane thr negative y axis is made to face down opposite the positive y axis
Whilst the negative x axis faces the left which is also alternate to the positive x axis
Generally A vector pointing towards the x and y negative axis fro the origin (0) will definitely be in the third quadrant
Answer:we can calculate the answer by following steps;
Explanation:
A)
The magnitude of the capacitive reactance is given by
where
is the angular frequency
C is the capacitance
While the magnitude of the inductive capacitance is given by
where L is the inductance.
Since we want the two reactances to be equal, we have
So we find
B) 7449 rad/s
In this case, we have
is the inductance
is the capacitance
Therefore, substituting in the formula for the angular frequency, we find
C)
Now we can us the formulas of the reactances written in part A). We have:
- Capacitive reactance:
- Inductive reactance:
Answer:
The forces that do non-zero work on the block are gravity and normal reaction force
Explanation:
In this question we have given,
mass of the wooden block,
angle between ramp and horizontal surface,
in this case ramp is friction less so friction force will be zero and hence work done due to friction force will be zero.
As wooden block is sliding down due to gravity(gravity is pulling the block in downward direction).
so two forces will act on wooden block as it slides down the ramp that are gravity and normal reaction force.
Therefore, the forces that do non-zero work on the block are gravity and normal reaction force.
