How much a substance increase its temperature due to heat transfer depends on its specific heat.
The specific heat is the amount of heat required to increase the temperature of one mass of substance in 1 °Celsius.
The lower the specific heat the more the substance change its temperature with a given amount of heat, the greater the specific heat of the substance the lesser the change of temperature with the same amount of heat.
Then, to predict which of the two blocks will have the greater rise you need to compare the specific heats of the metals.
From tables, the specific heat of gold is 0.129 J/g°C and specific heat of iron is 0.450J/g*°C.
Then, gold will raise more its temperature than iron, after the addition of the same amount of heat.
Answer:
U = 5.37*10^33 J
Explanation:
The gravitational potential energy between two bodies is given by:
G: Cavendish's constant = 6.67*10^-11 m^3/kg.s
For three bodies the total gravitational potential energy is:
BY replacing the values of the parameters for 1->earth, 2->moon and 3->sun you obtain:
hence, the total gravitational energy is 5.37*10^33 J
Tan x = 60/700
x = 4.9 degree east north
v = √(60^2 + 700^2)
v = 702.6 kph
hope this helps
In a spectrograph, black lines can be seen going through the array of colors. The pattern of these lines indicate the composition of the star.
Different elements block different parts of the spectrum, resulting in black lines.
