Answer:
When a switch is closed, electrons move through a circuit from the negative side of a battery to the positive side
Explanation:
Note that current is marked to flow from positive to negative on circuit diagrams, but that's for historical reasons only. Benjamin Franklin did a fabulous job of understanding what was going on, but no one yet knew about protons & electrons, so he assumed current was flowing from positive to negative.
However, what really happens is electrons flow from negative (where they repel each other) to positive (where they are attracted).
As electrons flow through a circuit, they need 'something to do'. In many cases, that something is to light a bulb or heat an element, such as an element on a stove. So, the energy of an electron can be converted to heat or light.
I hope I'm understanding your question correctly
What is the magnitude of the electric field at the dot in the figure? (E=? V/m) What is the direction of the electric field at the dot in the figure? 1. to the left 2. to the right 3. upward 4. downward Thanks!
Sounds but not solids
hoped this helped
The rock that is formed by metamorphosing shale is slate.
Answer:
Explanation:
Using Pascal laws, which states that pressure are the input equals the pressure at the output.
Pressure is given as force/area
P1=P2
Then,
F1/A1=F2/A2
Cross multiply
F1A2=F2A1
Given that
Ae=0.5m² area of effort
Al=5m² area of load
Fl=? Force if load
Fe= 100N. Force of effort
Then applying pascal
Fl/Al=Fe/Ae
Fl/5=100/0.5
FL/5=200
Fl=200×5
Fl=1000N
The first safety load is 1000N
