<span>A transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave.</span>
Answer:
The change in temperature of 576.9°C will produce an elongation of 9 inches per feet in steel.
Explanation:
The formula for linear expansion of a material is:
ΔL = αLΔT
where, ΔL = change in length
L = Original length
ΔT = Change in temperature
α = coefficient of linear expansion
For steel, α = 13 x 10^-6 /°C
L = 100 ft
ΔL = (9 in)(1 ft/12 in) = 0.75 ft
Therefore,
0.75 ft = (13 x 10^-6 /°C)(100 ft)ΔT
<u>ΔT = 576.9°C</u>

Should be just 2 km. - 2 km would mean it is moving in the opposite direction which come to think of it may be fine. You really can't tell.
Answer:
5.4 cm³
Explanation:
Ideal gas law:
PV = nRT
where P is absolute pressure, V is volume, n is number of moles, R is ideal gas constant, and T is absolute temperature.
Since n and R are constant, we can say:
PV / T = constant
At the bottom of the lake, the pressure is:
P = ρgh + Patm
P = (1000 kg/m³) (9.8 m/s²) (40.5 m) + 101,325 Pa
P = 498,225 Pa
And the temperature is:
T = 2.3 + 273.15 K
T = 275.45 K
At the top of the lake, the pressure is:
P = Patm
P = 101,325 Pa
And the temperature is:
T = 28.1 + 273.15 K
T = 301.25 K
Therefore:
PV / T = PV / T
(498225 Pa) (1.00 cm³) / (275.45 K) = (101325 Pa) V / (301.25 K)
V = 5.4 cm³
