Answer : The final equilibrium temperature of the water and iron is, 537.12 K
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.


where,
= specific heat of iron = 560 J/(kg.K)
= specific heat of water = 4186 J/(kg.K)
= mass of iron = 825 g
= mass of water = 40 g
= final temperature of water and iron = ?
= initial temperature of iron = 
= initial temperature of water = 
Now put all the given values in the above formula, we get:


Therefore, the final equilibrium temperature of the water and iron is, 537.12 K
The trajectory of their motion knocked the Earth into a different orbit.
There is a shortcut trick while doing such fill in the blanks of nuclear reactions of hydrogen and helium
Let a,b,care elements of set N

Now
for our question
Hence b=4-3+1=1+1=2
So
The missing place should b e deuterium of heavy water
In nuclear reactions energy is released so it's mentioned on product side not reactant side
Plants get the energy they need for photosynthesis from the sun
Answer:22.37 mph
Explanation:
100 meters = 0.062137 miles
Assume constant speed over the distance.
0.062137 miles in 10 sec
0.372822 miles in 60 sec = 1 minute
22.36932 miles in 60 minutes
22.37 mph rounded to 2 decimals
