Answer:

The reason wood burns more easily than most metals is because it doesn't actually burn, it vaporizes instead. When wood is heated, the molecules in the wood break down to form flammable gasses, which mix with the air and then burn.Then it takes more heat energy to trigger the reaction with oxygen. The amount of heat produced depends on the molecules that make up the fuel. ... For example, large pieces of wood take a lot longer to absorb heat energy to ignition temperature. A twig catches fire easily because it heats up easily

A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed.
chubhunter [2.5K]

Answer:

<h3>The answer is option D</h3>

Explanation:

To find the speed given the kinetic energy and mass we use the formula

v =  \sqrt{ \frac{2KE}{m} }  \\

where

m is the mass

v is the speed

From the question

KE = 15 J

m = 2.3 kg

We have

v =  \sqrt{ \frac{2 \times 15}{2.3} }  =  \sqrt{ \frac{30}{2.3} }  \\  = 3.61157559...

We have the final answer as

<h3>3.6 m/s</h3>

Hope this helps you
