all I know for that is Q=CV which doesn't seem to help can you please be more specific bc you're not helping me understand this. thanks

i still don't get it at all. would d=2R and I don't know the E here.. it isn't given

I don't know, that's all the question included...

so if F=qvB then V=Bq/F but when i plus in the charge for the electron is it negative or postive 1.6 x 10^-19 bc can a velocity be a negative answer?

Consider a parallel plate capacitor constructed from two circular metal plates of radius R. The plates are separated by a distance of 1.6mm a. What radius must the plates have if the capacitence is 2.8 micro F? b. if the separation between the plates is decreased, should the radius of the...

A charge of 3.45 micro C is held fixed at the origin. A second charge of 3.45 micro C (micro = x10^-6) is released at the position (1.15m, .77 m). a. If the mass of the second charge is 2.3 g, what is the speed when it moves infinately far from the origin? b. At what distance from the...

Homework Statement An electron moves at right angles to a magnetic field of .14T What is its speed if the force exerted on it is 8.7 X 10^-15 N? I am at a complete lossfor this question.

Homework Statement Find the acceleration that the cart in Figure 6-38 must have in order for the cereal box not to fall. Assume that the coefficient of static friction between the cart and the box is 0.40. ** the cereal box is at the front of the wagon (outside the wagon) Homework...

Homework Statement Hopping into your Porsche, you floor it and accelerate at 11.2 m/s2 without spinning the tires. Determine the minimum coefficient of static friction between the tires and the road needed to make this possible. Homework Equations well I know fs/N= the coefficient...

Homework Statement An object of mass m = 6.70 kg has an acceleration a = (1.17 m/s2)x + (-0.664 m/s2)y. Three forces act on this object: F1, F2, and F3. Given that F1 = (2.71 N)x and F2 = (-1.55 N)x + (2.05 N)y, find F3. ( N)x + ( N)y Homework Equations I'll be honest, i have no clue...

Homework Statement As shown in Figure 5-19, a force of magnitude 7.50 N pushes three boxes with masses m1 = 1.30 kg, m2 = 3.10 kg, and m3 = 5.80 kg. Figure 5-19 the figure depicts 3 boxes, in order m1, m2, m3 with a force pushing directly on m1 to the right on a flat level surface...

Homework Statement Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 5.0 mi/h, the time to go one mile decreases by 13 s. What was your original speed in mi/hr? Homework Equations X (which in...

my graoh was drawn by hand so is it a line between the pointss, or through??

best fit line? DOes that mean you draw a line/curve connecting the dots? Or does that mean you draw a line in between the dots leaving some above and some below? or does that mean you connect the dots but leave out the ones that dnt fit with the shape? please help

BEST FIT LINE ok I am supposed to make these for the graph. but does that mean i draw a line through the points, or have half points above and half below?? please explain (or do i just leave out points that dnt fit>.?)
