The answer is 0.5 km because 5 km/s divided by 10 Hz is 0.5. This makes your wavelength 0.5 km.
Answer:
Geology is the study of the Earth that involves the process at Earth, materials of which it is made, and its history.
<u>Geologists combine both laboratory and field data to illustrate the results of their research. Some observations that can the geologist make by working outdoors instead of in a lab are as follows:</u>
- Understanding and exploring the earth's surface closely using geophysical tools.
- Collecting samples by own and make some interpretations at the same time.
- Observation of the landscapes
- Close observation of outcrops
100 millimeters equals 0.1 meters.
Here in this case we can use energy conservation law to find out the speed
As per energy conservation we know that
initial kinetic energy + initial potential energy = final kinetic energy + final potential energy
so the speed of the pendulum bob is approx 2 m/s when it is 0.8 m above the floor
