Explanation:
wavelength = l
speed of wave = v
frequency = f
v = lf → f = v/l = 2.42 × 10⁴ ÷ 1.1 = 2.2 × 10⁴ 1/s
T = 1/f = 1/ 2.2 × 10⁴ = 0.45 × 10 -⁴ s
Answer:
Because of more rainfall.......
Explanation:
They receive more rainfall than low lying areas because the temperature on top of mountains is lower than the temperature at sea level. Winds carry moist air over the land. ... As the air rises, it cools, and because cool air can carry less moisture than warm air, there is usually precipitation (rain).
Answer:
-90.8 Joules
Explanation:
A = Area of container = 50 cm²
d = Length pushed = 15 cm
P = External Pressure = 121 kPa
Change in volume
Work done
Work done by the system is -90.8 Joules
