According to Keplar's second law of planetary motion, "The areas swept by the radial vector connecting the star (sun) and the planet orbiting it are equal for equal intervals of time
Explanation:
The given data is as follows.
= 0.8 kg/s = 800 g, 
= 1 kg = 1000 g, 
= (75 - T),
= T - 25
Now, according to the law of conservation of energy,
+ 30000
250.8 - 3.34T = 4.18T - 104.5 + 30
T = 
= 
Thus, we can conclude that temperature of the warm water stream is .
Answer:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate.
Explanation:
Anything that's dropped on or near the Earth accelerates at the rate of
9.8 m/s² on its way down. The mass of the object makes no difference.
After falling for 2 seconds, it's falling at the rate of 19.6 m/s.
Momentum = (mass) x (speed)
The egg's momentum is (5.07 kg) x (19.6 m/s) = 99.4 kg-m/s .
