Initial Distance 
Initial Electric field strength 
Final Distance 
Generally the equation for Electric field is mathematically given by.
Substituting q for 
Answer: Dynamic balance
Explanation: Dynamic balance movements are movements in which constant agonist-antagonist muscle contractions occur in order to maintain a certain position or posture. ISSA pg 121
Explanation:
neutron stars have diameters of about 20km and they are denser than the earth. A rotating neutron star pulsating electromagnetic beam is a named a pulsars but not all neutron stars are pulsars.
Only three of hundreds of known pulsar are found in supernova remnants because as neutron stars gets older, they lose energy and starts to decrease their rotational speeds and the neutron star could not radiate particles and energy for long as a pulsar does. there are less existing pulsars compared to supernova explosion rate because the life time of pulsars is obout 10×10^6 years after the neutron can no longer spin at high speeds to produce beams of particles and energy, almost all the pulsars are older and spin slow to produce light of visible wavelength or X-ray wavelengths and we only get a pulse of radiation from a neutron star as a pulsar as the beam sweeps over earth.
