Answer:
Explanation:
The equation for the magnetic field at the center of a circular loop is:
If we name the smaller loop as 1 and the bigger loop as 2 and we impose the same magnitude of the magnetic field at their center, we have:
Which for our values means:
(Notice that we don't need to convert cm to m, we get our result in cm).
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
