What happens to a circuit's resistance (R), voltage (V), and current (1) when you decrease the length of the wire in the circuit?

O A. Rincreases.

V decreases.

I decreases.

B. R decreases.

Vis constant.

Zincreases

C. Ris constant.

Vincreases.

/ increases.

D. Rincreases.

Vis constant

I decreases

D.

R increases

V is constant

I decreases

Explanation:

The resistance of a wire is given by the following formula:

It is clear from this formula that resistance is directly proportional to the length of wire. So, when length of wire is increased, the resistance of circuit increases.

The voltage in the circuit will be constant as the voltage source remains same and it is not changed.

Now, we can use Ohm Law:

V = IR

at constant V:

I ∝ 1/R

it means that current is inversely proportional to resistance. Hence, the increase of resistance causes the current in circuit to decrease.

Therefore, the correct option will be:

D.

R increases

V is constant

I decreases

b would be the answer

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
