Answer:
Sound waves travel at 343 m/s through the air and faster through liquids and solids. The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.
Your answer would be B because potential energy is an object's potential to move while kinetic energy is the energy of the object in motion. So if the apple is falling, then the potential energy would decrease and its kinetic energy would increase.
Hope this helps :)
Answer:
Explanation: p = mass x velocity = m x v. • p = 1000 x 30 . The product of the force (F) acting on an object and applied force) A 1000 kg Civic is traveling at 30 m/s and ... What is the momentum of the car after accelerating for ... If a 5kg object experiences a 10 N force . Solve: Honda, Camry, collision ... v = -15 m/s
Answer:
The upper levels of Neptune’s atmosphere appear blue because of the presence of Methane in its atmosphere .
Explanation:
Neptune -
Neptune is the eighth planet of the solar system ,
The composition of Neptune's atmosphere is mainly hydrogen , helium and methane gas .
The Methane in the atmosphere of the Neptune absorbs the red light from the sun and reflects the blue color into the atmosphere , Hence ,
