Answer:
yeah it can. well gravity is basically what's keeping us on earth without floating away. without gravity we would basically be floating like we're in space. ¯\_༼ ಥ ‿ ಥ ༽_/¯
Answer:
Explanation:
It takes 1200 J of work to lift a car high enough to change a tire.
The wavelength is 2m.
Hence, Option c) 2m is the correct answer
Given that;
Frequency;
Speed; 
Wavelength; 
using the expression for the relations between wavelength, frequency and speed of wave:

Where
is wavelength, f is frequency and v is speed.
We substitute our given values into the equation

The wavelength is 2m.
Hence, Option c) 2m is the correct answer.

The duck at 12m/s has a greater speed than the heron which travels at 10m/s
Speed=frequency x wavelength
if the medium is the same density and chemical make up all the way through then the speed is fixed because frequency is always unaffected. If density increases then speed decreases which means wavelength will decrease too.
