Answer:
Explanation:
The amount of heat released from water is equal to the sum of latent and sensible heats. Let suppose that water is initially at a temperature of 
. Then:
Finally, the amount of heat released from water is now computed by replacing variables:
![\Delta H_{tot} = (1\,mol)\cdot \left[\left(75.3\,\frac{kJ}{mol\cdot K} \right)\cdot (25^{\circ}C-0^{\circ}C)+ 6.025\,\frac{kJ}{mol} + \left(37.7\,\frac{kJ}{mol\cdot K} \right)\cdot (0 + 10^{\circ}C)\right]](https://tex.z-dn.net/?f=%5CDelta%20H_%7Btot%7D%20%3D%20%281%5C%2Cmol%29%5Ccdot%20%5Cleft%5B%5Cleft%2875.3%5C%2C%5Cfrac%7BkJ%7D%7Bmol%5Ccdot%20K%7D%20%5Cright%29%5Ccdot%20%2825%5E%7B%5Ccirc%7DC-0%5E%7B%5Ccirc%7DC%29%2B%206.025%5C%2C%5Cfrac%7BkJ%7D%7Bmol%7D%20%2B%20%5Cleft%2837.7%5C%2C%5Cfrac%7BkJ%7D%7Bmol%5Ccdot%20K%7D%20%5Cright%29%5Ccdot%20%280%20%2B%2010%5E%7B%5Ccirc%7DC%29%5Cright%5D)
I believe the government should encourage both children(society) do not know much about either because they are not taught enough about that subject/topic.
The first and third choices on the list will attract, because UNlike poles are facing across the gap.

Answer:
0.0107
Explanation:
We know that
The rotational kinetic energy due to four wheel is
1/2ဃ²I x 4
So
1/4mR²(v/R)² = mv²
But kinetic energy along straight path of the car is 1/2mv²
=> 1/2( 817)v ²
Kc= 408.5v²
So The fraction of total kinetic energy that is due to rotation of the wheel about their axis
Is Kw/Kw+Kc
and Kw = 1/2* 8.91v²= 4.45v²
So 4.45v²/ 4.45v²+ 408.5v²
= 0.0107 as fraction of total kinetic energy
The weight of the load is (mass) x (gravity)
= (350 kg) x (9.8 m/s²)
= 3,430 newtons .
The force on the surface of the liquid is the weight of the piston and its load.
The pressure on the surface of the liquid is (force) / (area)
= (3,430 newtons) / (1 m²)
= 3,430 pascals
= 3.43 kPa
This doesn't include anything for the weight of the piston without its load,
but it's certainly the closest of the choices.
