A 6 meter high tank is full of water. A hole appears in it . What is the speed of efflux? Which equation has the same solutions as x2+6x-7=0? Find a unit vector in the opposite direction as the given vector: v = 0.1i − 0.2 j.? Convert the equation to polar form. (Use variables r and θ as needed.)
x^2 − y^2 = 12? If amp has 0.5Ohm impedance and we connect a 0.36Ohm speaker but only use it at 20KHz where overall imedance is more than 0.5Ohm is that ok?
