Mass concerns amount of substance contained in an object etc. It won't change just because you moved to a place of different gravity. weight however will change because apart from mass , it is affected by the acceleration due to gravity so if it changes, the weight changes.
Answer:
20°C
Explanation:
Heat gained by the colder water = heat lost by the warmer water
m₁ C (T − T₁) = m₂ C (T₂ − T)
m₁ (T − T₁) = m₂ (T₂ − T)
(500) (T − 10) = (100) (70 − T)
5 (T − 10) = 70 − T
5T − 50 = 70 − T
6T = 120
T = 20
The final temperature is 20°C.
Potential Energy can be quantified as mass times gravity times height (PE=m*g*h). The unit for mass should be either kilogram or pound mass depending on the unit system. Gravity is a constant, 9.81 m/s² in SI units or 32.2 ft/sec² in English units.
To solve this problem we will use the mathematical definition of the light years in metric terms, from there, through the kinematic equations of motion we will find the distance traveled as a function of the speed in proportion to the elapsed time. Therefore we have to
means Light Year
Then
If we have that
Where,
v = Velocity
x = Displacement
t = Time
We have that
= Speed of light
Therefore will take 14.399 years
