Explanation:
When the wires of a circuit will break, circuit will be open state and stop the flow of current. Once the wires are reconnected, current will start flowing again in the circuit.
<span>Miller Urey experiment's purpose was to test the chemical origin of life under the conditions supposed to be present on the early Earth.
</span>The scientists Miller and Urey heated a mixture of water<span>, </span>ammonia<span>, </span>methane<span> and </span>hydrogen<span> in a sterile flask until it evaporated water to produce water vapour. </span><span>Electric sparks were passed through the mixture of </span>water vapour and gases, simulating lightning. The experiment was done during one week. After a week, the contents were analysed and Miller and Uray proved that <span>several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere.</span>
Mass
I believe mass is the correct answer
Answer: The correct answer for the fill in the blank is - medium of exchange.
Explanation-
When we use paper money to pay for food, the money is a medium of exchange as we are exchanging our money with their food. So, it plays a role of medium of exchange in purchasing our food.
On the other hand, unit of account is also a feature of money but it only indicates the price of food at which we are purchasing it. Store of value is used when we store our money as a wealth, then it becomes store of value .
Hence, medium of exchange is the correct answer.
m = mass of water in bathtub = 62.7 kg
= initial temperature of water in tub = 31 c
M = mass of water added = ?
= initial temperature of water added = 76 c
T = final equilibrium temperature of the system = 40.3 c
c = specific heat of water = 4186
Using conservation of heat
Heat gained by water in tub = Heat lost by water added
m c (T - ) = M c ( - T)
m (T - ) = M ( - T)
(62.7) (40.3 - 31) = M (76 - 40.3)
M = 16.3 kg
