Answer:32 m/s/s
Explanation: since F=M*A, F=16N, M=0.5kg, A= F/M
A=16/0.5
A=32 m/s/s
D) convection! here is the reason why :the definition of convection is <span>the concerted, collective movement of groups or aggregates of molecules within fluids (e.g., liquids, gases) and rheids, through advection or through diffusion or as a combination of both of them. So becuase the medal is more convective, this causes it to be heated faster!
Note; this is why we use glass heating plate, so they dont get hot and burn people</span>
Answer:1) Via heat: ferromagnet materials will lose their magnetism if heated above a point known as the Curie temperature. ... With a strong enough magnetic field of opposite polarity, it is therefore possible to demagnetize the magnet [whether this comes from another permanent magnet, or a solenoid].
Explanation:Unlike permanent magnets, temporary magnets cannot remain magnetized on their own. Soft magnetic materials like iron and nickel will not attract paper clips after a strong external magnetic field has been removed.To restore a permanent magnet, you need to cool the metal (if heated) and expose it to a magnetic field. Coil your copper wire tightly around the piece of metal you would like to restore as a permanent magnet.
Answer:
review or print them later.
Using the combined gas law of P1V1=P2V2 and plug it in you get (4)V1 for you don't have initial volume = (0.2)(500) --> 4V1=100, divide by the coefficient on both sides and you get V1=25
