Ba(MnO₄)₂ → Ba²⁺ + 2MnO₄⁻
MnO₄⁻ + 8H⁺ + 5e⁻ → Mn²⁺ + 4H₂O n=5
Answer:
15000N/m²
Explanation:
Given parameters:
Force exerted by the girl = 450N
Area = 300cm²
Unknown:
Pressure exerted by her feet =?
Solution:
Pressure is the force per unit area on a body;
Pressure =
We need to convert the given area to m²;
10000cm² = 1m²
300cm² =
= 0.03m²
Pressure =
= 15000N/m²
Answer:
False
Explanation:
Temperature is the degree of hotness or coldness of a body. Temperature is as a result of how much heat a body has. Heat is a form of energy called thermal energy. Heat can be transferred from one body to another as a result of differences in temperature between two bodies.
Chemical energy does not determine the temperature of a body. It is the amount of heat it contains.
