9. the scale most widely used by scientists for measuring earthquakes is the __ seismic scale richter scale moment magnitude scale epicenter magnitude scale 10. the instrument that records the seismic waves of an earthquake on paper is called a seismograph seismogram richtergram magnitude the richter magnitude of an earthquake is determined from the__ duration of an earthquake the intensity of an earthquake arrival times of p waves and s waves measurement of the amplitude of the largest seismic waves

9) Richter scale

10)Seismograph

11) measurement of the amplitude of the largest wave

I do believe to are correct

The correct answers are;  

9) Richter scale

10) Seismograph

11) measurement of the amplitude of the largest seismic wave

The Richter scale is a scale of numbers that is commonly used by scientists to measure the size (magnitude) of earthquakes. To determine the size of an earthquake using this scale, the logarithm of the amplitude of the largest seismic wave is adjusted to a scale by a seismometer.

Seismograph is the instrument that records the seismic waves of an earthquake. A seismograph automatically detects and records the direction, intensity and duration of earthquakes. Seismograph is made up of a mass that is joined to a fixed base.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
