The answer is:
The first option, the walker traveled 360m more than the actual distance between the start and the end points.
Why?
Since each block is 180 m long, we need to calculate the vertical and the horizontal distance, in order to calculate how farther did the travel walk between the start and the end points (displacement).
So, calculating we have:
Traveler:
Actual distance between the start and the end point (displacement):
Now, to calculate how much farter did the traveler walk, we need to use the following equation:
Therefore, we have that distance differnce between the distance covered by the walker and the actual distance is 360m.
Hence, we have that the walker traveled 360m more than the actual distance between the start point and the end point.
Have a nice day!
Answer:
Final temperature,
Explanation:
Given that,
Mass of silver ring, m = 4 g
Initial temperature,
Heat released, Q = -18 J (as heat is released)
Specific heat capacity of silver,
To find,
Final temperature
Solution,
The expression for the specific heat is given by :
So, the final temperature of silver is 21.85 degrees Celsius.
