Answer:
B.6.86 m
Explanation:
Given that
Compression in spring ,x= 9 cm
Spring constant ,K= 830 N/m
Mass of the rocket ,m= 50 g = 0.05 kg ( 1 kg = 1000 g)
Now by applying energy conservation


Now by putting the values ( we are taking g= 9.81 m/s²)

h= 6.853 m
Therefore the answer is B.
B.6.86 m
Soil and sand
Erosion is the movement of sand or sand particles caused by the fires of the wind
It definitely changes in frequency. For example if the frequency is medium the signals change after the sunset and it changes in the ionosphere cause medium frequency travels in the skywave.
