A small dense centre that has a positive charge and is surrounded by moving electrons is called an Atomic Nucleus.
Explanation:
Echo method formula for speed of sound : 2 x distance / time taken
2 x distance / 58 = 1540 m/s
2 x distance = 1540 m/s / 58 s
= 26.55172414 m
Distance = 26.55172414 / 2
= 13.27586207
= 13 m
Answer:
Explanation:
A fuse is an electrical safety device built around a conductive strip that is designed to melt and separate in the event of excessive current. Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s). A fuse connected in one branch of a parallel circuit, of course, would not affect current through any of the other branches.
Total Resistance=100+50=150
Power=V^2/R=(120)^2/150
=96W
