Answer:
d = V/E
Explanation:
From the definition, we can say that the electric field strength between the plates of a parallel plate capacitor is
E = v/d
where
E = electric field strength
V = potential difference
d = distance between the plates
On rearranging the equation and making d subject of the formula, we have
d = V/E
From the question, we're given that
V = 112 V
E = 1.12 kV/cm converting to V/m, we have 110000 V/cm
d = 112 / 110000
d = 0.00102 m
d = 1.02*10^-3 m
50 strands is the standard procedure
Answer:



Explanation:
By analyzing the torque on the wheel we get:
Solving for T: 
On the object:
Replacing our previous value for T:

The relation between angular and linear acceleration is:

So,

Solving for α:

The linear acceleration will be:

And finally, the tension will be:

These are the values of all the variables: α, a, T
Answer:
2.7 s
Explanation:
The period of the motion of a massless loaded spring is given by

where m is the mass of the load and k is the force or spring constant.
Using values in the question and converting to appropriate units,

The distance covered by the object between t =4 s and t = 6 s is 4 m
Explanation:
In a velocity-time graph, the distance covered by the object represented can be found by calculating the area under the curve.
Therefore, the distance covered by the object between t = 4 s and t = 6 s is the area under the curve between 4 s and 6 s.
We see that we have to calculate the area of a triangle, with:
Base:

And height:

Therefore, the area is

So, the distance covered by the object is 4 m.
