Answer:
3×10⁵ N/m²
Explanation:
From the question given above, the following data were obtained:
Force (F) = 450 N
Area (A) = 0.0015 m²
Pressure (P) =?
Pressure is simply defined as the force per unit area. Mathematically, it is expressed as:
Pressure (P) = Force (F) / Area (A)
P = F/A
With the above formula, we can obtain the pressure exerted by the man on the ground. This can be obtained as follow:
Force (F) = 450 N
Area (A) = 0.0015 m²
Pressure (P) =?
P = F/A
P = 450 /0.0015
P = 3×10⁵ N/m²
Thus, the pressure exerted by the man on the ground is 3×10⁵ N/m².
Answer:
I'm ok at it.
Explanation:
I can try to help if you need anything:)
Answer: More than 700 different types of igneous rocks are known. Sedimentary rocks form by the compaction and cementing together of sediments, broken pieces of rock-like gravel, sand, silt, or clay. ... Metamorphic rocks form when the minerals in an existing rock are changed by heat or pressure below the surface.
Hope this helps (:
Answer:
The answer to your question is Endothermic reaction
Explanation:
Endothermic reactions are reactions that absorbe energy from the environment.
All the reactions that needs heat to proceed are endothermic, example: photosynthesis, reactions in the laboratory that are heated, heat our meals.
This is an endothermic reaction because the enthalpy of the products is higher than the enthalpy of the reactants,
