The second major phase in the break-up of Pangaea began in the Early Cretaceous, when the minor supercontinent of Gondwana separated into multiple continents (Africa, South America, India, Antarctica, and Australia).
The South China Sea is definitely a significant body of water, considering that lots of fishing boats and cargo ships (trading) passes through. China is trying to secure a claim on it that is far wider than their EEZ (Exclusive Economic Zone).
Answer: 5040 joules
Explanation:
How much energy is released when 150g of silver cools from 220°C to 80°C?
Given the following :
Mass (m) of silver = 150g
Change in temperature (ΔT) = (220 - 80)°C = 140°C
Q=mcΔT
Where Q = quantity of heat
m = mass of silver ; c = specific heat capacity
Specific heat capacity of silver = 0.240 j/g°C
Q = (150 * 0.240 * 140)
Q = 5040J
Answer:
Uncalibrated radiocarbon measurements are usually reported in years BP where 0 (zero) BP is defined as AD 1950. BP stands for “Before Present” or “Before Physics” as some would refer to it. It should be noted that a BP notation is also used in other dating techniques but is defined differently, as in the case of thermoluminescence dating wherein BP is defined as AD 1980.
