Answer:
0.159 Tesla per second
Explanation:
r = 2 m, e = 2 V,
Let the rate of magnetic field changing is dB / dt.
By use of Farady's law of electromagnetic induction
e = rate of change of magnetic flux
e = dФ /dt
e = A x dB / dt
2 = 3.14 x 2 x 2 x dB / dt
dB / dt = 0.159 Tesla per second
Explanation:
An Example of push as a force would be to push on a swing. The force moves the swing in a particular direction and the harder that you push the further the swing will go.
An example of pull as a force would be opening a door. ...
An example of pressure as a force is when you push down on a pile of grapes. is this what you mean
Answer:
7 m/s
Explanation:
Acceleration, 
Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.
Making v the subject then
v=at+u
Taking u as zero then
Substituting 3.5 for t, 2 as a then
v=3.5*2=7 m/s
