Answer:
it is defined as splitting up the given force into a number of components, without changing its effects on the body is called resolution of forces. A force is generally resolved along with two mutually perpendicular directions.

When you heat a certain substance with a difference of temperature 

 the heat (energy) you must give to it is

where 

 is the specific heat of that substance (given in J/(g*Celsius))
In this case

Observation: the specific heat of a substance is given in J/(g*Celsius) or J/(g*Kelvin)  because on the temperature scale a 
difference of 1 degree Celsius = 1 degree Kelvin
 
        
        
        
The length of the inclined plane is approximately 12 ft
The situation forms a right angle triangle. 
<h3>Right triangle</h3>
Right triangle have one of its angle as 90 degrees.
Therefore,
The length of the inclined plane is the hypotenuse of the triangle. The length of the inclined plane can be found using trigonometric ratios.
height = 4 ft
angle(∅) = 19.45°
sin 19.45 = 4 / h
h = 4 / 0.33298412235
h = 12.0125847796
h = 12 ft
Therefore, the length of the inclined plane is approximately 12 ft

Here's the tool you need.  You can't answer the question without this:
           "1 watt" 
means 
           "1 joule of energy, generated, used, or moved, every second".
So      60 watts  =  60 joules per second
           Total energy generated, 
            used, or moved                  = (power) x (time).
                                     580 joules  =  (60 watts) x (time)
Divide each side 
by  (60 watts):              Time  =  (580 joules) / (60 joules/sec)  
                                               =  (9 and 2/3)  seconds  .
