The object moves linearly, and its velocity drops linearly from $v_0$ to zero. Calculate the amount of electromagnetic energy emitted by it. Equation for Energy lost by a particle in linear motion: $\frac{dE}{dt} = -\frac{q^2}{16\pi^2} \int_0^{\pi} \int_0^{2\pi} \frac{\dot{v}(t)^2 \sin^2\theta}{(1 - v(t)\cos\theta)^5} \sin\theta \,d\phi \,d\theta$ $= -\frac{q^2}{8\pi} \dot{v}(t)^2 \int_0^{\pi} \frac{\sin^3\theta}{(1 - v(t)\cos\theta)^5} d\theta$ $= -\frac{q^2}{6\pi} \frac{\dot{v}(t)^2}{(1 - v(t)^2)^3}.$ Pls make as many intermediate steps as possible!

Inhibitor-absorber is found near the arachnoid layers. 14. The microglia emit mitochondria. 16. In the nervous system, white matter refers to the brain:spinal cord, while grey matter refers to the cortex:brainstem. 17. The structure which connects the right and left hemispheres is called the corpus callosum. 18. The main function of the occipital cortex is visual. 19. The cerebellum contributes to the control of movement. 20. Damage to the motor pathways in the spinal cord would result in a loss of movement. 22. The hypothalamus helps to govern motivated behaviors like sex & aggression, and to regulate hormonal systems involved in hunger and thirst. 23. If a neurosurgeon stimulates your brain and your left finger twitches, it is likely the left motor cortex was stimulated. The meninges is a protective coverage for the brain, while ventricles are fluid-filled spaces in the brain.
