Here, We know, Density = Mass / Volume
Here, mass = 249.8 g
volume = 92.5 cm³
Substitute their values,
d = 249.8 / 92.5
d = 2.7 g/cm³
In short, Your Answer would be "Aluminum"
Hope this helps!
Answer:
he gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation )

Answer:
Explanation:
When a substance is supplied with a certain amount of heat energy, the temperature of the substance increases according to the equation
where
m is the mass of the substance
Q is the amount of energy supplied
C is the specific heat of the substance
is the temperature change
In this problem:
Q = 758 J is the energy supplied
m = 0.750 kg is the mass of the sample
is the specific heat of copper
Re-arranging the equation, we can find the increase in temperature:
