If the coefficient alpha for a stress scale was computed to be 0.80, the scale would be strongly reliable. A coefficient alpha that is at least 0.70 and above is considered to have a strong internal consistency, which means the items in the scale are closely related as a group.
Average velocity = (length and direction of displacement) / (time for the displacement).
Displacement = 5 m north
Time = 10 s
Average velocity = (5 m north/(10 s)
Average velocity = 0.5 m/s north
They're never the same ray.
The acceleration is (144 m^2/s^2) divided by (the radius of the centrifuge).
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.
