1 Kilojoule [kJ] = 737.562 149 277 27 Foot pound force [ftlbf]
Answer:
When the resistances are connected in the parallel the equivalent resistance will be always less than the value of the lowest resistance in the parallel circuit.
The equivalent resistance in the parallel circuit can be calculated using the following formula.
1/R=1/R1+1/R2+1/R3
1/R= 1/10+1/20+1/30
1/R=(6+3+2)/60
1/R=11/60
R=60/11
R=5.45 Ohms
Gravitational Potential Energy = weight x height
for 1 meter:
GPE = 5 x 1
= <u>5N</u>
for 1.5 metres:
GPE = 5 x 1.5
= <u>7.5N</u>
for 2 metres:
GPE = 5 x 2
= <u>10N</u>
