In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.
MARK ME BRAINLIEST PLEASE!!!!
Answer:
The mercury in the barometer rises by a height of 0.0764 m = 76.4 cm = 764 mm
Explanation:
The change in pressure is related to the density of fluid and height risen by the fluid through the relation
ΔP = ρgh
ΔP = change in pressure = P₂ - P₁ = 1.1 - 1.0 = 0.1 atm = 0.1 × 101325 Pa = 10132.5 Pa
ρ = density of the fluid = 13,534 kg/m³
g = acceleration due to gravity = 9.8 m/s²
h = height through which the mercury in barometer rises = ?
10132.5 = 13534 × 9.8 × h
h = (10132.5) ÷ (13534 × 9.8)
h = 0.0763948996 = 0.0764 m = 76.4 cm = 764 mm
Hope this Helps!!!
Answer: 35000 J or 35kJ
Explanation:
Use equation for kinetic energy : Ek=mV²/2
m=700 kg
V=10m/s
-------------------
Ek= 700kg*100m²7s²/2
Ek=35000 J=35kJ
Answer:
12 cm/s
Explanation:
Quite simply, you are looking for cm/s
so 60 cm / 5s = 12 cm/s
