Answer:

increasing its thickness

Explanation:

there are four major factors that affect the resistance of a metal wire, they are;

1. the length of the wire: the longer the length of a wire the higher the resistance

recall R=ρL/A

the above equation shows a direct relation between resistance and length

2. the temperature of the wire: the higher the temperature of a wire when heated up, the higher the resistance of the wire

3. the thickness or width of the wire: the higher the thickness the lower the resistance.

from the equation in 1 above, there is an inverse relationship between resistance and area(diameter inclusive) of a wire

4. the material of the wire: different wires have different values of resistivity(ρ). steel  shows higher levels of resistivity than copper

therefore, increasing thickness reduces resistance

Compare the benefits of wildfires to grasslands, northern forests, and deciduous forests.
Dimas [21]
Wildfires benefit grasslands, northern forests, and deciduous forests. Grasslands are benefited by improved soil quality and control of tree cover. Invertebrate species diversity is maintained through wildfire as well. Northern forests, like grasslands, experience increased production and nutritional quality of food as a result of wildfires. Deciduous forests experience an increase in the nutritional quality of food as well, but the effects are more temporary. The amount of shrubs in deciduous forests is reduced as a result of wildfires, allowing more herbaceous plants such as mosses and lichens to grow.

The distance recorded for riding a motorcycle on its rear wheel without stopping is more than 320 km! Suppose the rider in this
antiseptic1488 [7]

Answer:

<h3>14.97m/s</h3>

Explanation:

Given

Initial velocity of the car u = 8m/s

Distance travelled by the rider S = 40m

Acceleration a = 2m/s²

Required

rider's velocity after the acceleration v

Using the equation of motion

v² = u²+2as

v² = 8²+2(2)(40)

v² = 64+160

v² = 224

v = √224

v = 14.97m/s

Hence the rider's velocity after the acceleration is 14.97m/s
