Answer: It is identified with color, texture, boiling point, melting point and freezing point
Explanation:
Answer:
These linear thermal expansion coefficients are room temperature values of metals. Linear thermal expansion coefficient is defined as material's fractional change in length divided by the change in temperature.
Explanation:
Answer:
Height, h = 0.51m
Explanation:
Given the following data;
Mass = 10kg
Gravitational potential energy = 50 Joules
To find the change in height;
Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.
Mathematically, gravitational potential energy is given by the formula;
Gpe = mgh
Where,
Gpe represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Substituting into the formula, we have;
50 = 10*9.8*h
50 = 98h
h = 50/98
h = 0.51m
