Answer:
1.10^6 kg of mass per second
Explanation:
All energy lost by the sun comes from nuclear fusion.
Sun loses energy at 2.5*10^{19}J per hour, that is 9*10^{22}J/s
To find the mass lost by the sun in liberation of energy you use the famous Einstein's equation:
hence, the sun liberates 1.10^6 kg of mass per second
Basic truss bridge types found in North Carolina (source: HAER) A truss bridge can be characterized by the location of its traffic deck. At a pony truss, the travel surface passes along the bottom chords of trusses standing to either side that are not connected to each other at the top.

Answer:
Change in temperature =7.14° C
Explanation:
Assuming all potential energy of cylinder is converted into heat energy to increase the temperature .
Work done by gravity in first case =m *g*h= 3*10*500=15000
Let quantity of water be 1 kg at 0°C.
Also specific heat capacity of water is =4200 Joule
So potential energy is converted to m*4200*T(1) =15000
T(1)=3.57
Work done by gravity in first case =m *g*h= 9*10*500=45000
Here also potential energy is converted into m*4200*T(2)=45000
T(2)=10.71
Here temperature is increasing.
Thus change in temperature =T(1) -T(2) =7.14° C
