Answer:
The correct option is;
A) Steel becomes too hot in the Sun and can burn the children
Explanation:
The properties of steel includes;
Low specific heat capacity, high thermal and electrical toughness, high hardness, high tensile strength, high yield strength, appreciable elongation, high fatigue strength, can easily corrode, high malleability and ability to creep
Therefore, due to the low specific heat capacity, which is 0.511 J/(g·°C) and high conductivity of steel which is about 32 W/(m·k), the temperature of the steel can rapidly rise and the hot steel surface can readily conduct the heat, (due to the temperature difference) to other bodies that come in contact
Answer:
0.667 per day.
Explanation:
Our values here are
Degradation constant=k and is unknown.
We calculate the concentration through the formula,
Replacing values we have
That is the degradation constant of Z-contaminant
hey thanks for the point's i really needed them.. Cheers!
