Answer:
I think it is O only nonliving
Kinetic Energy = 1/2mv^2
The solution is attached below.
Answer:
1) A time-varying magnetic field will produce an electric field.
4) A time-varying electric field will produce a magnetic field.
Explanation:
1) A time-varying magnetic field will produce an electric field.
TRUE
time varying magnetic field will produce electric field which is given as
2) Time-varying electric and magnetic fields can propagate through space only if there is no matter in their path.
FALSE
Time varying electric field and magnetic field will induce each other and it can travel through any medium as well as it can travel without any medium also
3) Electric and magnetic fields can be treated independently only if they vary in time.
FALSE
electric field can be due to stationary charge and magnetic field due to current carrying elements so it is not compulsory to have time varying
4) A time-varying electric field will produce a magnetic field.
TRUE
Time varying electric field will produce magnetic field given as
Answer and Explanation:
1. Evaluate the function x(t) at t=0.5
2. The period of motion T can be calculated as:
Where:
So:
3. The angular frequency can be expressed as:
Solving for k:
4. Find the derivate of x(t):
Now, the sine function reach its maximum value at π/2 so:
Solving for t:
Evaluating v(t) for 0.6603981634:
So the maximum speed of the block is:
In the negative direction of x-axis
5. The force is given by:
The cosine function reach its maximum value at 2π so:
Solving for t:
Evaluating x(t) for 3.016592654:
Therefore the the maximum force on the block is:
