Answer:
Wave speed = Wavelength x Frequency
26 m/s = Wavelength x 49
Divide by 49 to find the wavelength:
The wavelength is approximately 0.53
Let me know if this helps!
The closer together they are the harder it is to hold on to because the magnetic field is stronger as it gets closer.
Answer:
D. The electromagnet's magnetic field is stronger close to it than far from it.
This is because planet weigh different amount and force of gravity is different from planet to planet for example if your weigh on earth is 100 pound than on mercury is only 78 pounds
