Answer:

Color. The changing of color of a substance is not necessarily an indicator of a chemical change. For example, changing the color of a metal does not change its physical properties. However, in a chemical reaction, a color change is usually an indicator that a reaction is occurring.21-Aug-2020

What is the potential difference between xi=10cm and xf=30cm in the uniform electric field Ex=2000V/m? Express your answer to tw

Novay_Z [31]

Answer:

∆V= -400 Volts

Explanation:

xi= 10 cm= 0.1 m

xf= 30 cm = 0.3 m

E= 2000 V/m

We have the equation

∆V=-E (∆d)= E (xf -xi)

∆V=-2000V/m (0.3 -0.1)m

∆V= -400 Volts
