Which surface produces the least friction when someone walks on it

Physics
1 answer:
Alika [10]3 years ago
6 0

Answer: B Ice

The friction depends on the texture of the surface. A rough surface has more friction. The carpet or wooden surface that we usually walk on have fairly enough friction. We don't slip on sand also much but to walk on ice it requires spokes as you also see while doing ice skating it is very difficult to stand on ice. This is because of low friction on ice floor.

malfutka [58]

Here Change in Kinetic Energy = Work Done by Friction

Therefore, substituting the given values to the equation, we get

0.5 * m * (vFinal^2 - vInitial^2) = µ m g * d

Therefore

0.5*( 5.90^2 - Vfinal^2 ) = 0.100*9.8*2.10

Therefore

vfinal = 5.54 m/sec

The reaction 4Al + 3O₂ → 2Al₂O₃ is a synthesis or also called combination reaction because reactants combine to produce a new compound (Option 2).

<h3>What is a synthesis combination reaction?</h3>

In chemistry, a synthesis or combination reaction is any type of chemical reaction in which two or more molecules called reactants combine to produce one or more molecules called products of such reaction.

Therefore, with this data, we can see that a synthesis or combination reaction is a chemical process where two or more molecules combine to produce a new molecule known as a product.
