1. $y'' - y + t^2 = 0$ 2. $t^2 \frac{d^2y}{dt^2} + t \frac{dy}{dt} + 2y = \sin t$ 3. $(1 + y^2) \frac{d^2y}{dt^2} + t \frac{dy}{dt} + y = e^t$ 4. $y'' - y + y^2 = 0$
Consider three equipotential surfaces at electric potentials -9V, 0V and +9V as shown in the figure below with the separation distance between them. -9.0 V 0V +9.0 V 3.2 cm 3.2 cm A. The electric field between the surfaces of -9.0V and +9.0V is [Select] V/m, and it points [Select] B. The electric field between the surfaces 0V and +9.0V is [Select] V/m pointing [Select] C. Now, consider an electron moving between the surfaces. The change in the electric potential energy (?U) of this electron when it moves from 0V to +9.0V surface is [Select] eV, and it is [Select] D. If the electron was at rest at 0V surface, the kinetic energy of the electron when it reaches +9.0V surface will be [Select] eV, which equals [Select] in Joules. E. The direction of the electric force acting on the electron when it moves in the E-field between the equipotential surfaces: 0 V to +9.0 V is [Select]
