Answer:
The value is
Explanation:
From the question we are told that
The weight of the block is
The dimension of the block is
Generally two atmosphere is equivalent to
Generally 1 atm =
The area of the block would be evaluated using width and height because we need for the smaller surface to be in contact with the ground in order to maximize the pressure and minimize number of blocks
So
=>
Generally the force due to this blocks is mathematically represented as
Here N is the number of blocks
So
=>
The heat energy transferred by the iron nail is 4680 J
Explanation:
The thermal energy transferred by a substance to another substance is given by the equation
where
m is the mass of the substance
C is its specific heat capacity
is its change in temperature
For the iron nail in this problem, we have:
m = 16 g
So, the amount of heat energy given off by the nail is
where the negative sign indicates that the heat is given off.
