The Answer is False. Energy does Get recycled in the Ecosystem.
Answer:
43.1 g
Explanation:
Density, d is defined as the mass per unit volume of an object. Density is therefore expressed as
d=m/v
Here, m is mass and v is the volume
Making mass the subject of the formula
Mass, m=dv
The volume, v is given by
V=lwh
Substituting lwh for v in the equation for mass then mass, m=dlwh
Substituting 2.6 g/cm3 for d, 4.0 cm for l, 1.8 m for w and 2.3 for h then the mass of the block will be
M=2.6*4*1.8*2.3=43.056 g
Expressing it in 1 decimal place, mass is approximately 43.1 g
Force is a vector, it has direction, it can move objects and it was well described with laws by physicist Isaac Newton by which the units of force were named Newtons (N).
