1 answer:
Answer:
39 miles
Explanation:
we will make your house to be the central point in the four cardinal points.
Please follow the diagram on the attachment to get the movement clearly.
First, you move to a dry cleaners 12miles east of your house, and then to a grocery store 15miles west of your house.
This means you must have moved back to your house before going to the grocery which is 15miles west of your house.
so to and fro from your house to dry cleaners = 12*2 = 24 miles.
Then the total distance you cover will be = 24 +15 = 39 miles

Answer:
b. 9.5°C
Explanation:
= Mass of ice = 50 g
= Initial temperature of water and Aluminum = 30°C
= Latent heat of fusion =
= Mass of water = 200 g
= Specific heat of water = 4186 J/kg⋅°C
= Mass of Aluminum = 80 g
= Specific heat of Aluminum = 900 J/kg⋅°C
The equation of the system's heat exchange is given by
The final equilibrium temperature is 9.50022°C
