Answer:
Density = 11.11 kg/m³
Explanation:
Given the following data;
Mass = 40 kg
Dimensions = 30×4×3 = 360 cm³ to m³ = 360/100 = 3.6 m³
Thus, volume = 3.6 m³
Now, we can find the density;
Density can be defined as mass all over the volume of an object.
Simply stated, density is mass per unit volume of an object.
Mathematically, density is given by the equation;
Substituting into the equation, we have;
Density = 40/3.6
Density = 11.11 kg/m³
Answer:
40 cm
Explanation:
We are given that
Load=800 N
Effort=200 N
Load distance=10 cm
We have to find the effort distance.
We know that
Using the formula
Effort distance=
Effort distance=
Effort distance=40 cm
Hence, the effort distance will be 40 cm.
