Answer:
From the initial height h
Explanation:
When a material or substance is drop from a height h, it possesses potential energy, immediately it is dropped from that height, the potential energy is gradually converted to kinetic energy, it gets to a point where the potential energy equals the kinetic energy, as the material touches the ground, all potential energy has been converted to kinetic energy already
Answer:
What happens to the wavelength of a wave if you double the frequency?
If the frequency of a wave is increased, what happens to its wavelength? As the frequency increases, the wavelength decreases. 2. If the frequency is doubled, the wavelength is only half as long.
Explanation:
Answer:
The factors in the physical environment that are important to health include harmful substances, such as air pollution or proximity to toxic sites the focus of classic environmental epidemiology access to various health-related resources e.g. healthy or unhealthy foods, recreational resources, medical care.
I think it is;
Current = vtotal/requ
2A = vtotal/0.5
2*0.5= vtotal
1=vtotal
