Explanation 1) Concept: By using the formula for magnetic force acting on a moving charged particle, we can find the magnetic field B. 2) Formula: Magnetic force, F B → = q v → × B → 3) Given: i) Charge on the particle q = 2.0 C ii) Velocity of the particle v → = ( 2.0 i ^ + 4.0 j ^ + 6.0 k ^ ) m s 2 iii) Force acting on the particle F B → = ( 4.0 i ^ - 20 j ^ + 12 k ^ ) N 4) Calculations: a) To find the magnetic field, we use the formula for magnetic force in terms of velocity and magnetic field. Let the magnetic field vector be B → = ( B x i ^ + B y j ^ + B z k ^ ) T As it is given that x and y components of magnetic field are same, B x = B y B → = ( B x i ^ + B x j ^ + B z k ^ ) T We have F B → = q v → × B → Therefore, we can write 4.0 i ^ - 20 j ^ + 12 k ^ = 2 × i j k 2 4 6 B x B x B z By solving the matrix, 1 2 4

Defination of voltage

At point A, 3.20 m from a small source of sound that is emitting uniformly in all directions, the intensity level is 58.0 dB. What is the intensity of the sound at A? How far from the source must you go so that the intensity is one-fourth of what it was at A? How far must you go so that the sound level is one-fourth of what it was at A?

Make a plot of the acceleration of a ball that is thrown upward at 20 m/s subject to gravitation alone (no drag). Assume upward is the +y direction (and downward negative y).
