Answer:
They studied different models.
Explanation:
Newton's laws pertained to the study of objects based on the concepts of gravity. Forces between the planetary bodies were give by the universal law of gravitation of Newton.
Kepler's 3 laws defined the orbits of the planets, and also a way to relate their orbital radius to their time periods and the velocity law. According to the law of speed, if a planet is close to the Sun it will move faster and if it is farther away from the sun, it slows down and will have lesser speed.
According to Newton's gravitational law , a planet that is closer to the sun experiences a greater force or gravitational pull and vice versa.
Answer:
2.98 m/s^2
Explanation:
I have done this before and it was a question on my physics test
Answer:
Water leaves the sprinkler at a speed of 2.322 m/sec
Explanation:
We have given internal diameter of the garden
Speed of water in the hose is
Number of holes n = 22
Diameter of each holes
According to continuity equation
So water leaves the sprinkler at a speed of 2.322 m/sec
Answer:
having only magnitude, not direction
Explanation:
the 2nd one because it says no direction
Answer:
15.65 °C
Explanation:
cold temperature (Tc) = -15.5 degree C = 273.15 - 15.5 = 257.65 kelvin
minimum coefficient of performance (η) = 8.25
find the maximum hot reservoir temperature of such a generator (Th)
η = \frac{Tc}{Th-Tc}
Th = Tc x (\frac{1}{η} + 1)
Th = 257.65 x (\frac{1}{8.25} + 1)
Th = 288.8 K
Th = 288.8 - 273.15 = 15.65 °C
