Box 4: Making things move Explain the relationship between the python code
force = -G*sun. M*earth. M*R/magR**3
and the equation
F⃗ = −GmSmE Rˆ . R2
Hint: starting with the vector R⃗ how can we find the unit vector Rˆ which points in the direction of R⃗? Remember that we use in python we use ** for exponentiation so that magR**3 means (magR)3.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
