Answer:

Butane is a four member carbon chain.

The properties of butane are as follows.

Butane is less denser than water.

In the presence of air, it readily burns to form water vapour and carbon dioxide. The reaction is as follows.

           

It has a boiling point of .

Butane has faint petroleum like odor.

Butane does not react with water.

Butane has weak dispersion force and water has strong hydrogen bonding.  The weak dispersion force is unable to break the hydrogen bonding hence, butane does not dissolve in water.

Thus, we can conclude that the chemical properties butane burns readily in air and does not react with water are true out of the given list of options.

A skateboarder traveling at 7.0 meters per second rolls to a stop at the top of a ramp in 3.0 seconds. What is the skateboarder’
ki77a [65]

Answer:

-2.33 m/s²

Explanation:

The computation of the skateboarder’s acceleration is shown below;

Acceleration means the change in velocity per unit with respect to time.

In the given case, the initial velocity is 7 m/s.

As in the question it is mentioned that  it comes to a stop, so the final velocity would be zero.

And, The time elapsed is 3 seconds.

Now the following equation should be used  

a = (v,final - v,initial) ÷ t

=  (0 - 7)/3

= -2.33 m/s²

Two forces of 6 lbs and 8 lbs act on an object. If these two forces form an angle of 60, then find the magnitude of the resulta
yawa3891 [41]

Answer:

The magnitude of Resultant force is F = 7.21-lbs

Explanation:

Two forces acting on an object which are named as F1 and F2.

The angle formed by the forces are 60-degrees

F1 = 6-lbs , F2 = 8-lbs

theeta = 60°

F = √F1²+F2²-2(F1)(F2)cos(theeta)

F = √(6)²+(8)²-2(6)(8)cos(60)

F = √36+64-(96)cos(60)

F = 7.21-lbs

where,

F1 = magnitude of force 1

F2 = magnitude of force 2

theeta = angle formed by forces
