Answer:
T_2= 234.37 K
Explanation:
According to Claperyon, we know that
P_1= Atmospheric pressure 760 mm Hg
P_2 = pressure at the bottom of the column
= 10×10^3 mm of Hg+ 760 mm of Hg
= 10760 mm of Hg
now,
P_2-P_1= 10760-760= 10^4 mm
P_2-P_1 ( in pascals) = 10^4× 133.322= 1333220 mm
the enthalpy of fusion (ΔH-fus) of mercury is 2.292 KJ/mol
use the above equation to calculate ΔT as follows
therefore, T_2= 234.37 K
The correct answer to go in the blank would be A) The particles are moving faster.
<em>The question doesn't ask about anything in particular. I'll compute the net force as a guide, so you can solve your own problem.</em>
Answer:
The net force is zero
Explanation:
<u>Net Force
</u>
If we want to compute the net force exerted on a body, we must add them as vectors, i.e. the horizontal and vertical components independently.
The box has 4 forces, as follow
40 N right
40 N left
10 N up
10 N down
The vertical forces are equal and opposite, i.e. their sum is zero. The same situation happens in the horizontal direction, both forces are of equal magnitude and opposite, their sum is zero. The net force is then, zero in both axes
Explanation:
The total energy of the system remains conserved. It just converts from one form of energy to another.
The battery of the cell phone contains chemicals. As the electricity is passed through the cell phone, the electrical energy is converted to chemical energy. As she notices that the phone is warm and after the battery has been fully charged and the student unplugs her cell phone, the phone vibrates when a message arrives, this shows the conversion of chemical energy to mechanical energy, thermal energy etc.
Hence, we can say that the correct option is (b).
