Answer:
I = 9.82 10⁻⁷ W / m²
Explanation:
The intensity of the sound wave is the energy of the wave between the order per unit area of the same
I = P / A = E / T A
the energy is calculated by integrating the mechanical energy in a period, where the mass is changed by the density and ‘s’ is the amplitude of the sound wave
I = ½ ρ v (w s)²
I = ½ 1.35 328 (2π 530 2.00 10⁻⁸)²
I = 221.4 (4.435 10⁻⁹)
I = 9.82 10⁻⁷ W / m²
Use formula of resistance for Parallel circuit
(refer to photo)
V = I * R
Voltage = Current * Resistance
I hope this helped.
Answer:
Wave height is the vertical distance between the crest (peak) and the trough of a wave. Some other definitions: Still-Water Line is the level of the lake surface if it were perfectly calm and flat. Crest is the highest point on the wave above the still-water line.
Explanation:
Answer:
orbit the sun have very elliptical orbits
are made of frozen gas and ice
Explanation:
Comets are the made up of dry ice, frozen water, gases and dust particles. it is called dirty snow balls as their nucleus carry frozen water and pieces of rock.
Comets move around the sun in an elliptical orbits and follow Kepler's Laws saying that they move faster when closer to the Sun.
Comets have tails even when they are far from the sun and the tails that point away from the sun.
Hence, the correct options are "orbit the sun have very elliptical orbits and are made of frozen gas and ice".
Answer:
The temperature would get warmer.
Explanation:
It indicates heat from earth’s warm interior surface. The temperature increases for about 25℃ for every single kilometer of depth.
