Correct matching:
1 acceleration -->
rate of change in velocity, which is the change in velocity divided by the change in time
2. speed --> the rate at which an object changes position when traveling in a certain direction
4. gravity --> force of attraction between all masses in the universe
5. Inertia --> an object´s resistance to a change in motion
3. friction --> force of resistance acting between objects in contact and tending to dampen their motion
6. velocity --> the rate at which an object changes position
Red shift of distant galaxies
Answer:
Final temperature of the copper is 59 degrees Celsius
Explanation:
It is given that,
Mass of the sample of copper metal, m = 6.5 g
Initial temperature of the metal, 
Heat generated, Q = 84 J
The specific heat capacity of liquid water is 0.38 J/g-K
Let 
is the final temperature of the copper. It can be calculated using the definition of specific heat of any substance. It is given by :
or
So, the final temperature of the copper is 59 degrees Celsius. Hence, this is the required solution.
The correct answer to the question above is the capture theory. The capture theory proposes that the moon was a passing asteroid pulled into the orbit by the Earth's gravity. It says that the moon was originally orbiting the sun, not the Earth.
