Answer: Total Thermal Energy
Explanation: The total kinetic energy of moving particles of matter is called thermal energy. The thermal energy of matter depends on how fast its particles are moving on average, which is measured by temperature, and also on how many particles there are, which is measured by mass.
Answer:
I may be wrong but I think it is C.
Answer:
178 ft
let t1 = drop time, let t2 = time for sound to travel up to you, Y = well depth
t1 + t2 = 3.5
Y = 1087 t2 = 16 t1^2
Substitute: t2 = 3.5 - t1
16 t1^2 = 1087 (3.5 - t1)
16 t1^2 = 3804.5 - 1087 t1
16 t1^2 + 1087 t1 - 3804.5 = 0
Solve via quadratic equation: t1 = 3.336 s, t2 = 0.164 s
Y = 178 ft
