A, B, and C are hilarious. D is correct.
Charges can be positive or negative, so a pair of charges can be alike or opposite. But so far, we've never seen a negative mass.
Answer:
<h3>30.405°C</h3>
Explanation:
Using the formula for heart capacity;
Q = mcΔt
m is the mass = 150g = 0.15kg
initial temperature = 22°C
Quantity of heat = 3240J = 3.24kJ
specific heat capacity of ethanol = 2.57 [kJ/kg K]
Substitute and get the final temperature
3.240 = 0.15(2.57)(T - 22)
3.240 = 0.3855(T-22)
3.240/0.3855 = T - 22
8.405 = T - 22
T = 22+8.405
T = 30.405°C
Hence the final temperature of the ethanol if 3240 J was needed to raise the temperature of the ethanol is 30.405°C
Answer:
Natural gas is non renewable energy.
Explanation:
Because they were formed from the buried reamains of plants and animals that live a million years ago. It is formed from fossil fuels.
Continuing in an existing state. Resistance to change.
