Answer:
Correct Option is (a).
Explanation:
Order of increasing hardness is
Most plastics < cutting tools < brass < diamond
Diamond is the hardest from all above.
Diamond is formed from carbon atoms only and each carbon atom is attached to 4 other carbon atoms in tetrahedral geometry due to which it has a highly compact structure.
Brass is basically an alloy of two metals copper and zinc.
It is harder than its constituent metals but softer than diamond.
Plastics are least hard from the given options.
The closer you get to the equator the warmest you will be. 10 degrees north is warmer than 80 degrees north, because 10 degrees north is closer to the equator. I don't know if that was helpful or not but, I tried to answer as best as I could.
Answer:
C
Explanation:
The cold doesn't mean water (A), the age of the desert doesn't mean much in this context (B), that doesn't make any sense (D), but the desert being an ocean in the past does explain where the fossil came from because the organism would have been in the area before death.
The value of interest plug in the equation for calculating loan's effective interest rate is 0.085. Thus, option C is correct.
The loan effective interest rate has been given as the rate that has been effectively charged on the principal amount. In the calculation of the interest, the percentage sign has not been considered.
Thus, the interest rate has been converted to the values by dividing the percent to 100.
The effective interest rate (<em>EIR</em>) for the equation has been:
The given interest rate has been 8.5 % . The value plug in the equation has been,
The value of interest plug in the equation for calculating loan's effective interest rate is 0.085. Thus, option C is correct.

Answer:
Option 3. Specific heat capacity of the liquid
Explanation:
Let's think, the states for the substance.
In -10, substance turns from solid state to liquid, so at 2°C , state is liquid.
We have to take from liquid state at 2°C to 155°C, which is the boiling point.
As the substance doesn't change its state, we only have to apply the specific heat capacity of the liquid.
1. specific heat capacity of the solid → This is used, when the substance is solid.
2. Heat of fusion → Only used when you turn from liquid to solid
4. Heat of vaporization → Used when the substance changes its state from liquid to gas
5. specific heat capacity of the gas → Used when the substance is a gas.
