The sharp nail has a less surface area in comparison to a blunt nail and pressure is inversely proportional to area so it is easier to Hamer a sharp nail into a wood rather than having a blunt nail in wood
Answer:

Explanation:
the cow gets oxygen from the tree and proceeds to respirate.
In the beginning, the melting stage they call it.
Answer:
a) (1.4 + 1.9) = 3.3m/sec.
(35/3.3) = 10.6 secs.
b) (1.9 - 1.4) = 0.5m/sec.
(35/0.5) = 70 secs.
Explanation:
The temperature of the body is equal to 39.48°C
Why?
To find the temperature of the body that produces 9.0cm of this mercury column, we need to use the formula for linear interpolation. Also, the temperatures to use are based on the Celsius degrees scale.
For the fixed tempetatures, we have:

We need to use the following formula for linear interpolation:

Then, we have:

So, interpolating we have:

Hence, the temperature of the body is equal to 39.48°C
Have a nice day!
