An example of conductors of heat would be iron pans. a example of electric insulators would be copper, gold and silver. to contrast conductors and insulators, insulators let electricity pass through them while conductors restricts electricity. both conductors and insulators can work with lithium and sodium.
Answer:The Doppler effect is a change in the frequency of sound waves that occurs when the source of the sound waves is moving relative to a stationary listener.
As the source of sound waves approaches a listener, the sound waves get closer together, increasing their frequency and the pitch of the sound. The opposite happens when the source of sound waves moves away from the listener.
Explanation:
Melting freezing and boiling are molecular changes
Answer:
the answer is d
Explanation:
from F=Q1Q2
r².
then wen both charges are doubled
F=2Q1 ×2Q2
r²
F=4Q1Q2
r²
then 4 has to be the factor multiplied by the other part of the equation for it to balance
4F=4Q1Q2
r²
so theoretically the 4 on the LHS can cancel the 4 on the RHS
