Answer:
the angle must decrease to maintain balance and that the system remains motionless
Explanation:
In a system of a block in an inclined plane, using Newton's second law
X Axis Wₓ-fr = 0
Y Axis N - = 0
The equation for the force of friction is
fr = μ N
And using trigonometry for weight components
sin θ = Wₓ / W
cos θ = W_{y}/ W
Wₓ = W sin θ
W_{y} = W cos θ
We replace
Wₓ = fr
W sin θ = μ Wcos θ
tan θ = μ
If the coefficient of friction decreases the force of static friction decreases, ₓso the value of the tangent must decrease so the angle must decrease to maintain balance and that the system remains motionless or with constant speed
Electric field is defined as force per unit charge.
So it is given by
now we can find electric field by
So field strength is 0.75 N/C.
Answer:
three light sources at different directions, maybe of different sizes and intensity
The maximum current in the resistor is determined by dividing root mean square current by 0.7071.
<h3>
Maximum current in the resistor </h3>
The maximum current in the resistor is calculated as follows;
I₀ = I(rms)/0.7071
where;
- I₀ is the peak current or maximum current in the resistor
- I(rms) is the root mean - square current
Thus, the maximum current in the resistor is determined by dividing root mean square current by 0.7071.
