Sound can be used to alert us in emergencies. 2. Sound can also be used to help blind people navigate the world better. I’m sorry if these horrible but I tried lol
The answer is A.
215K is equivalent to -58.15 °C and temperature corresponds with the average kinetic energy.
So the 15°C has a higher energy level than 215K.
1.58 × 10^(-10) in
<em>Step 1</em>. Convert picometres to metres
4.01 pm × [10^(-12) pm]/[1 m] = 4.01 × 10^(-12) m
<em>Step 2</em>. Convert metres to inches
4.01 × 10^(-12) m × 39.37 in/1 m = 1.58 × 10^(-10) in
