It is a graph. It shows observations and then you record your results with any of the graph types.
The gravitation field strength of Planet X is 10 times that of Earth's, as the object weight has increased 10 times. This is only possible if the planet is more massive or more dense (smaller diameter).
Therefore, the answer is C.
Answer:
The first fossils were marine reptiles called plesiosaurs. They were found on Seymour Island in 1982. The first dinosaur fossil was an ankylosaur, found on James Ross Island in 1986.
Explanation:
Answer:
0.053 J/gºC
Explanation:
From the question given above, the following data were obtained:
Mass (M) = 540 g
Heat (Q) = 257 J
Temperature rise (ΔT) = 9 °C
Specific heat capacity (C) =?
The specific heat capacity of mercury can be obtained as illustrated below:
Q = MCΔT
257 = 540 × C × 9
257 = 4860 × C
Divide both side by 4860
C = 257 / 4860
C = 0.053 J/gºC
Therefore, the specific heat capacity of mercury of mercury is 0.053 J/gºC
