A proton is released at the origin in a constant electric field of 850 N/C acting in the positive x-direction. Find the change in the electric potential energy associated with the proton after it travels to x = 2.5 m.

After a parallel-plate capacitor is charged by a battery, it is disconnected from the battery and its plate separation is increased. Which of the following statements is correct?

The electric potential at x = 3.0 m is 120 V, and the electric potential at x = 5.0 m is 190 V. What is the electric field in this region, assuming it's constant?

A helium nucleus (charge = 2e, mass = 6.63 10-27 kg) traveling at a speed of 6.20 105 m/s enters an electric field, traveling from point circle a, at a potential of 1.50 103 V, to point circle b, at 4.00 103 V. What is its speed at point circle b?

A battery is attached across several different capacitors connected in series. Which of the following statements are true? 1 The capacitor with the largest capacitance carries the largest charge. All the capacitors have the same charge, and the equivalent...

If three unequal capacitors, initially uncharged, are connected in series across a battery, which of the following statements is true? 1 The equivalent capacitance is greater than any of the individual capacitances. The capacitor with the smallest capacit...

A piece of wood discovered in an archaeological dig was found to have lost 62% of it's carbon-14. Carbon-14 has a half-life of 5630 years. Determine it's age.

Solve n + 1 = -4

Can I simplify (12960 - 0.1x^2) / 0.2x^2 any further? How?

The demand x is the number of items that can be sold at a price of $p. For x = p^3 - 4p + 400, find the rate of change of p with respect to x by differentiating implicitly.

Recently, a certain bank offered a 10-year CD that earns 8.93% compounded continuously. a) If $20,000 is invested in this CD, how much will it be worth in 10 years? Ans: I used the formula A = Pe^(rt) to get the answer $48,848.92 b)How long will it take f...

Let f(t) give the area in square miles of a town in a year t and the area of square miles. Find a formula for g by scaling the output of f. Use the fact that 1 mile is equal to 1.609 kilometers.

Thank you! How would I solve 1 = (12960 - 0.1x^2) / 0.2x^2

It's the same person saying they have a 3/10 btw I got a 100%

Plz don't off of steves answers most of them are wrong ;-;
