Answer:
a
Explanation:
its the heaviest and its putting out the same force as the lighter ones
Magnetic field is produced by the magnet which will flow through any attractive item or even substance such as ferrofluid. Happy I could help:)
Answer:
28 N
Explanation:
According to Newton's second law of motion
The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
in another form,
Force = mass * acceleration
assuming mass is a constant since considering the same object , we can say
Force ∝ acceleration
Frequency is indirectly proportional to the wavelength, in other words, when frequency increases wavelength decreases and vice-versa
c = ∧f
Hope this helps!
