If a projectile is launched from the ground which of the following periods of angles will result in the same horizontal range? A) θ = 45⁰, θ =30⁰
B) θ = 60⁰, θ =45⁰
C) θ = 90⁰, θ =30⁰
D) θ = 30⁰, θ =60⁰
E) θ = 75⁰, θ =25⁰

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

i believe the answer is a hope it and is correct

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
