Answer:
The change in temperature, 
Explanation:
Given that,
The temperature in Spearfish, South Dakota, rose from 
in just 2 minutes. We need to find the temperature change in Celsius degrees. Change in temperature is given by final temperature minus initial temperature such that,
The relation between degrees Celsius and degrees Fahrenheit is given by :
Here, F = 49 degrees
So, the change in temperature is 9.45 degree Celsius. Hence, this is the required solution.

Therefore
Use your feet to stop it since it is soccer you can't use your hands!!!! P.S. you can't use gravity.
The answer is; C
In particular points in the earth’s surface, underground water is naturally heated to steam that can be harness for geothermal energy. The steam that ejects from the ground with high kinetic energy can be used to turn turbines that generate electricity. The underground water is usually heated by the hot rocks beneath that are subjected to the immense heat of magma or the enormous pressure of overlying crust.
Answer:
When the electrical current passes through the conductors, the polarity is changed, and the diaphragm interacts with the permanent magnets, vibrating and creating sound.
