Option d: copper.
Because copper is an element, not a mixture.
The average speed is zero if our frame of reference is the rotation of the Earth because the relative distance with respect to the earth is zero.
Average speed = 0.26 km/hr
total time = 316 minutes
distance = speed * time
= 8.3 * 5*1/30 = 8.3 *1/6
= 1.38 km
Average speed = total distance / total time
1.38 km / 5.27
= 0.26 km/hr
Distance is described to be the importance or length of displacement among positions. observe that the gap between two positions is not the same as the distance traveled between them. Distance traveled is the whole period of the path traveled among positions. Distance traveled isn't a vector.
There are three foremost styles of average: imply, median, and mode. each of these strategies works barely otherwise and frequently results in slightly distinct ordinary values. The suggest is the maximum usually used commonly. To get the mean cost, you add up all of the values and divide this general by means of the variety of values.

Answer:
22.44°C will be the final temperature of the water.
Explanation:
Heat lost by tin will be equal to heat gained by the water
Mass of tin = 
Specific heat capacity of tin = 
Initial temperature of the tin = 
Final temperature = 
=T
Mass of water= 
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = =T
On substituting all values:
we get, T = 22.44°C
22.44°C will be the final temperature of the water.
The answer is D. A compound
