2.                                 What
is the main difference between Engineering notation and Scientific notation ?
Give examples. Enginering notation oly allows three digits to the left of the
decimal, it has to be written in multiple of three.

3.                                 What
is the difference between AC and DC voltages? Give examples.

AC is alternating current that can
shange directions. DC only flows in one direction.

6.            A mass of 1000kg is dropped through
a height of 16m in 22s. What is

(a)          The work done 160000 J    =160KJ Power*work/time    =160000/22
= 7272.73J/s =7.272KJ/s

(b)          The power developed?

10x60x6=3600Wh = 36
kWh

(c)           100×4= 4 = 400W= 0.4 Wh

(d)          1000x3x3=9000=9 WH Work=Power X Time =
3600×90+400×90+9000×30=630000J = 630kJ

Results Comment;

There was a small
variation between the recistans results.. This variation could have been caused
by the rounding off numbers. This method might not lso not work for those who
are colorblind.

Conclusion;

Band, You have to know the Color-Code which we used during the experiment.

There
might have been bad connections used in the experiment. Temperature can also
affect the results.

The sum of voltages across loop
BCDB  is equivalent to 0. This equation
proves Kirchhoff’s voltage law.

The sum of voltages across loop
ABCDA is equivalent to 0. This equation also satisfies Kirchhoff’s voltage law.

The sum of voltages across loop
ADCA is equivalent to 0. This equation also satisfies Kirchhoff’s voltage law.

The sum of voltages across loop
ABCA is equivalent to 0. This equation also satisfies Kirchhoff’s voltage law.

From our experiment, it is clear
that the sum of  the currents going into
a junction is equl to the sum of currents leaving that junction.

Conclusion;

Kirchhoff’s Law shows the total
current or charge going into a junction has the same value as  the charge leaving the node because it has no
were else to go. ”The sum of all current going in and out of a node equals
zero. This I shown in our experiment.
