Answer:

How well a material conducts an electrical charge and is measured in ohms.

Explanation:

Resistance is the property of a conductor which opposes the flow of electric current. Its SI unit is ohms and represented by $\Omega$ . According to Ohm's law voltage is directly proportional to the current flowing through the circuit.

It depends directly on the length of the conductor and inversely on its area of cross section. It measure how well a material conducts an electrical charge. Hence, the correct option is (b).

An 80-kg bungee jumper jumps off a bridge. Rubber bungee cords act as a large spring attaching the jumper to the bridge. A bear

inysia [295]

Answer:

The force is $F_b = 216 \ N$

Explanation:

From the question we are told that

The mass of the bungee jumper is m = 80 kg

The spring constant is $k = 20 \ N/ m$

The extension of the rubber bungee cords is x = 50 m

Generally the weight of the jumper is

$W = m * g$

=> $W = 80 * 9.8$

=> tex]W = 784 \ N [/tex]

Generally the returning force of the rubber bungee cords is mathematically represented as

$F = k * x$

=> $F = 20 * 50$

=> $F = 1000 \ N$

The force to be applied by the bear is

$F_b = F - W$

=> $F_b = 100 - 784$

=> $F_b = 216 \ N$

Explain how water is controlled to generate electrical energy in hydro-electric dams. and show a diagram is help explain the ans

kirza4 [7]

Here is how I would I explain it. Water is channeled through tunnels in the dam. The energy of water flowing through the dam’s tunnels cause turbines to turn. The turbines make generators move. Generators are machines that produce electricity. Engineers control the amount of water let through the dam. The process used to control this flow of water is called the intake system.

Hope this helps can’t do the diagram part.
