Answer:
the force remains constant if the charge does not change
Explanation:
In a capacitor the capacitance is given by
C = ε₀ A / d
Where ε₀ is the permissiveness of emptiness, A is about the plates and d the distance between them.
The charge on the capacitor is given by the ratio
Q = C ΔV
Let's apply these expressions to our problem, if the load remains constant
C = Q / ΔV = ε₀ A / d
ΔV / d = Q / ε₀ A
If the distance increases the capacitance should decrease, therefore if the charge is a constant the voltaje difference must increase
Now we can analyze the force on the test charge in the center of the capacitor
ΔV = E d
E= ΔV/d
F = q E
F = q ΔV / d
Let's replace
F = q Q /ε₀ A
From this expression we see that the force is constant since the voltage increase is compensated by increasing the distance, therefore the correct answer is that the force remains constant if the charge does not change
Answer:
0.0545 m/s2
Explanation:
19.2 cm = 0.192 m
We can convert rpm (revolution per minute) to angular velocity rad/s knowing that each revolution is 2π rad and each minute is 60 seconds.
57 rpm = 57 * 2π / 60 = 6 rad/s
86 rpm = 86 * 2π / 60 = 9 rad/s
The angular acceleration of the sprocket is the change in angular velocity per unit of time
The tangential acceleration of the pedal is the product of its angular acceleration and the radius of rotation, aka the pedal arm length L = 0.192 m
The amount of gravitational pull an object experiences is its mass
<h3>
What is Weight ?</h3>
Weight can be define as gravitational pull an object. It is a product of mass and acceleration due to gravity. That is, W = mg. It is measured in Newton (N)
The amount of gravitational pull an object experiences is its mass and not density because the weight of an object depend on its mass and acceleration due to gravity.
W = mg
where
- g = acceleration due to gravity
Therefore, the amount of gravitational pull an object experiences is its mass
