Answer:
In Newtonian mechanics, the gravitational energy possessed by a mass, because of the gravitational field produced by a second mass.
Explanation:
It will help them stay in better shape resulting in better health, being more physically active, and staying happier as a result.
Answer:
180m
Explanation:
We can use the formula [ d = st ].
12 * 15 = 180m
Best of Luck!
If you take a fluid (i.e. air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is<span><span> not heated.</span> </span>
Answer:
0.686 g of ice melts each second.
Solution:
As per the question:
Cross-sectional Area of the Copper Rod, A = 
Length of the rod, L = 19.6 cm = 0.196 m
Thermal conductivity of Copper, K = 
Conduction of heat from the rod per second is given by:
where
= temperature difference between the two ends of the rod.
Thus
Now,
To calculate the mass, M of the ice melted per sec:
where
= Latent heat of fusion of water = 333 kJ/kg
