2. An object with an initial speed of 4.0 meters per second accelerates uniformly at 2.0 meters per second in the direction of its motion for a distance of 5.0 meters. What is the final speed of the
object?

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.

Hello @mmmhhbhb,how are you doing? i will answer each question individually below! i hope it ! remember to contact me if you need further assistance!   1. what is the wave speed of a wave that has a frequency of 100 hz and a wavelength of 0.30 m? 100 hz x .30 m = 30 m/s2. what is the wave speed of a wave that has a frequency of 50 hz and a wavelength of 0.10 m? 50 hz x .10 m = 5 m/s3. what is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m? 20 m/s divided by .50 m = 40 hz4. what is the frequency of a wave that has a wave speed of 80 m/s and a wavelength of 0.20 m? 80 m/s   divided by .20 m = 400 hz5. what is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m? 120 m/s divided by .40 m = 300 hz6. what is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 440 hz? 340 m/s divided by 440 hz = .77 m7. what is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 880 hz? 340 m/s divided by 880 hz = .38 m8. what is the wavelength of a sound wave that has a speed of 250 m/s and a frequency of 400 hz? 250 m/s divided by 400 hz = .63 m9. what is the wave speed of a wave that has a frequency of 50 hz and a wavelength of 2.0 m? 50 hz x 2.0 m = 100 m/s10. what is the wave speed of a wave that has a frequency of 100 hz and a wavelength of 0.50 m? 100 hz x 0.5 m = 50 m/sthat's all, hope i !   you,  darian d.
