Answer:
a. The human body has nearly the same density as salt water after exhaling.
b. The human body will always float in the Dead Sea.
Explanation:
According to the concept of floating on the basis of density, any body that is put in a fluid of density greater than its own density will always float due to the force of buoyancy from the liquid.
- The portion of the object submerged while the object is floating depends upon the density of the object as compared to the density of the fluid. This is governed by the equation:
where:
density of the fluid
density of the object
volume of the object submerged in the fluid
total volume of the object
P = 43 * 10^3
V = 12 L
P' =?
V' = 8 L
PV = P'V'
43*10^3* 12 = P' * 8
I know you can do it from here, mate ;)
Answer:
0.000136kg/m3
Explanation:
13.6 / 1000 = 0.0136kg/cm3
0.0136 / 100 = 0.000136kg/m3
Sublimation is a type of printing that involves heat and a special type of printer. You use specialized ink to print onto transfer paper then place the paper on the item you are sublimating and then you heat press it for the allotted time.
Answer:
C: the total energy is conserved
Explanation:
In a closed system they total mechanical energy is always conserved although energy may change from one form to another
