(a) To determine The radius of the disk. Explanation Write the expression for the voltage. V = ( 2 k Q a 2 ) ( x 2 + a 2 − | x | ) (I) Here, V is the voltage, k is the constant, Q is the charge, a is the radius and x is the distance from the charge. Write the expression for the electric field. E = ( 2 k Q a 2 ) ( ± 1 − x x 2 + a 2 ) (II) Here, E is the electric field. Divide Equation (II) from Equation (I). E V = ( ± 1 − x x 2 + a 2 ) ( x 2 + a 2 (b) To determine The charge on the disk.

You're on an interplanetary mission, in an orbit around the Sun. Suppose you make a maneuver that brings your perihelion in closer to the Sun but leaves your aphelion unchanged. Then you must have Question 2 options: sped up at perihelion sped up at aphelion slowed down at perihelion slowed down at aphelion

The force of the quadriceps (Fq) and force of the patellar tendon (Fp) is identical (i.e., 1000 N each). In the figure below angle in blue is Θ and the in green is half Θ (i.e., Θ/2). A) Calculate the patellar reaction force (i.e., R resultant vector is the sum of the horizontal component of the quadriceps and patellar tendon force) at the following joint angles: you need to provide a diagram showing the vector and its components for each part. a1) Θ = 160 degrees, a2) Θ = 90 degrees. NOTE: USE ONLY TRIGNOMETRIC FUNCTIONS (SIN/TAN/COS, NO LAW OF COSINES, NO COMPLICATED ALGEBRAIC EQUATIONS OR ANYTHING ELSE, ETC. Question A has 2 parts!
