The specific heat of the given sample of metal is 14.32 J/kg.K.
<h3>What is the Specific heat of a sample?</h3>
The specific heat of a sample is the amount of heat needed or required to raise the temperature of that sample by 1K. It is given by the formula:
Q = mCΔT
where;
- Q = Heat transferred
- m = Mass of the substance
- C = Specific heat
- ΔT= Change in temperature.
Recall that:
weight of a substance = mass × gravity
- mass = 28.4 N/ 9.8 m/s²
- mass = 3 N/m/s² = 3 kg
From the equation:
Q = mCΔT

C = 14.32 J/kg.K

Photosynthesis because it allows the plant to produce sugars from sunlight.
The area of an irregular shape can be found by dividing the shape into polygons with gaps between them: True.
<h3>What is a polygon?</h3>
A polygon is a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:
In Geometry, the area of an irregular shape can be found by dividing the shape into polygons with gaps between them and then add their areas together.
