Work formula:
W = F * d
F 1 = 40 N, d 1 = 6 m;
F 2 = 30 N; d 2 = 6 m.
W ( Cindy ) = 40 * 6 = 240 Nm
W ( Andy ) = 30 * 6 = 180 Nm
The difference of their amounts if work:
240 Nm - 180 Nm = 60 nm
hope it helps!
I think 11 is B! 12 is A! 13 is B and 14 is A

The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.
not giving you the answer but hopefully this gives a hint
Answer:
The unknown frequency is either 438 Hz or 442 Hz.
Explanation:
The frequency of a beat heard when two sounds with frequencies f₁ and f₂, are played simultaneously, is simply the difference between two frequencies.
b = |f₁ - f₂|
b = 2 Hz
f₁ = 440 Hz
f₂ = ?
440 - f₂ = 2 or 440 - f₂ = -2
f₂ = 438 Hz or 442 Hz
The unknown frequency is either 438 Hz or 442 Hz.
Hope this Helps!!!
