Answer:
Acceleration = 1.33m/s² East
Explanation:
Given the following data;
Initial velocity = 10m/s
Final velocity = 50m/s
Time = 30secs
To find the acceleration;
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
Where,
a is acceleration measured in
v and u is final and initial velocity respectively, measured in
t is time measured in seconds.
Substituting into the equation, we have;
Acceleration = 1.33m/s² East
Answer:
The value is
Explanation:
From the question we are told that
The radius of the inner conductor is
The radius of the outer conductor is
The potential at the outer conductor is
Generally the capacitance per length of the capacitor like set up of the two conductors is
Here is the permitivity of free space with value
=>
=>
Generally given that the potential of the outer conductor with respect to the inner conductor is positive it then mean that the outer conductor is positively charge
Generally the line charge density of the outer conductor is mathematically represented as
=>
=>
Generally the surface charge density is mathematically represented as
here
=>
