Explanation Given info: The potential difference is 25.0 kV . Write the expression to calculate the work potential energy of electron. E = e V Here, E is the work potential energy of electron. e is the charge on electron. V is the potential difference. Substitute 1.6 × 10 − 19 C for e and 25.0 kV for V in above expression. E = 1.6 × 10 − 19 C × 25 kV × 1000 V 1 kV = 4 × 10 − 15 J Thus, the potential energy of electron is 4 × 10 − 15 J . Write the expression to calculate the Kinetic Energy of Electron. 1 2 m v 2 = E v = 2 E m Here, m is the mass of electron. v is the final speed of electron. E is the work potential energy of electron. Substitute 9.1 × 10 − 31 kg for m and 4 × 10 − 15 J for E in above expression

Frame of reference

In physics, a frame of reference is a coordinate system used to specify either the position or the orientation or velocity of a body. The origin of the coordinate acts as a reference point for measuring the position or relative motion of a body. The coor…

A man holds a double-sided spherical mirror so that he is looking directly into its convex surface, 33 cm from his face. The magnification of the image of his face is +0.17. What will be the image distance when he reverses the mirror (looking into its concave surface), maintaining the same distance between the mirror and his face? Be sure to include the algebraic sign (+ or -) with your answer.

How do you draw a diagram of the ruler and mass system in equilibrium identifying the anti-clockwise torque and clockwise torque? How do I calculate the anti-clockwise torque and the clockwise torque of the system with the ruler and the washers, does it come from the data in table 4? Please help, thank you!
