Answer:
So the answer would be water based on the evidence shown below.
Explanation:
Mercury is a poor conductor of heat but good for electricity, water is a good conductor of heat but a poor conductor of electricity, wood is a poor conductor of heat and electricity, and glass is probably the worst conductor of heat. 
 
        
             
        
        
        
Answer:
Explanation:
Initial angular velocity ω₀ = 151 x 2π / 60
= 15.8  rad /s 
final velocity = 0 
Angular deceleration α = 2.23 rad / s 
ω² = ω₀² -  2 α θ
0 = 15.8² - 2 x 2.23 θ
= 55.99  rad 
one revolution = 2π radian 
55.99 radian = 55.99  / 2 π no of terns
= 9 approx . 
 
        
             
        
        
        
Pure water.
A salt solution contains impurities whereas pure water will not contain any impurities.
Impurities increase the boiling point (freezing point) of a substance.
Thus, I would expect the pure water solution to freeze faster than the salt solution.
        
             
        
        
        
Answer:
The final temperature of the gas is <em>114.53°C</em>.
Explanation:
Firstly, we calculate the change in internal energy, ΔU from the first law of thermodynamics:
ΔU=Q - W
ΔU = 1180 J - 2020 J = -840 J
Secondly, from the ideal gas law, we calculate the final temperature of the gas, using the change in internal energy:


Then we make the final temperature, T₂, subject of the formula:



Therefore the final temperature of the gas, T₂, is 114.53°C.
 
        
             
        
        
        
Answer 
Se togli 15 mph da 95 e 15, capisci quanto tempo la macchina 2 fa da 0 mph a 70 mph. La prima macchina fa da 0 mph a 60 mph in 5 secondi, e la seconda da 0 mph a 70 mph in 5 secondi. Risulta essere più veloce la seconda macchina. Spero di essere stato utile :)
