the Olympic flame at the 1992 Barcelona Olympic was lit by a flaming arrow shot from a point located 60 meter horizontally and 24 meter vertically from the flame. find the initial speed necessary for the arrow to reach the flame at the peak of its trajectory. ?

** urgent** the voltage across the primary winding is 350,000 v, and the voltage across the secondary winding is 17,500 v. if the secondary winding has 600 coils, how many coils are in the primary winding? a- 30 coilsb- 583 coilsc- 12,000 coilsd- 332,500 coils

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
