P and Q are points within a uniform electric field that are separated by a distance of 0.2 m as shown. The potential difference between P and Q is 75 V. How much work is required to move a +150 μC point charge from P to Q? 0.023 J 140 J 0.011 J 2800 J 75 J

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

grav force prop 1/r squared 2r all squared is 4rsquared 1/4rsquared quartered

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
