Answer is D..by applying formula W=Fs ..10×2 = 20
For the chart, for the chart, melting would be it goes from a solid to a liquid and heat would be removed.
Hi there!
The equation for the electric field of a point charge is given by:
E = Electric Field (N/C)
k = Coulomb's Constant
r = distance (m)
We can rearrange to solve for 'q':'
Plug in the values and solve:
Answer:
Storing it at a temperature greater than its Curie temperature will demagnetize it. The Curie temperature--named after the French scientist Pierre Curie--is the temperature at which magnets lose their permanent magnetism. ... Samarium cobalt, neodymium, and ceramic/ferrite magnets are brittle.
