Answer:
h = 11.67 m
Explanation:
Mass, m = 0.249 kg
Spring constant, k = 4975 N/m
Compression, x = 0.107 m
Energy stored in the spring,W, is:
W = 0.5kx²
W = 0.5*4975*0.107²
W = 28.48N·m
The potential energy is given by the formula:
PE = mgh
PE = 0.249*9.8*h
PE = 2.4402h
According to energy conservation principle, Potential Energy = spring energy.
That is, PE = W
2.4402h = 28.48
h = 28.48/2.4402
h = 11.67 m
I think it’s when the sun explodes because since we need to the sun I think the human population will fall out. also a huge war, a meteoroid huge as the one that killed the dinosaurs comes down, there is so much ways on how the human population can stop growing. hope this help at least!
Answer:
Radio waves have frequencies as high as 300 gigahertz(GHz)to as low as 30 hertz(Hz).At 300 GHz the corresponding wavelength is 1mm and at 30Hz is 10,000 km
