Homework Statement I just need help on a simple question, In a parallel circuit with 3 bulbs, if one bulb is removed, will the intensity of the other 2 bulbs remain the same or increase? thanks much!

if i have 4.1E-3 c/s then wouldn't i have to multiply that by the one electron? 4.1E-3 x 1.6E-19 = 6.56E-22 but like you said since it is one minute and there are 60 seconds in a minute i would multiply 6.56E-22 by 60 in order to get 3.9E-20 im sorry for all this, but I am just really...

if i am sort of understanding what you are saying, you mean to use my answer for part a in order to get my answer for part b? well i have tried something like that, but i still must be off track because i still got it wrong 4.1E-3 x 6.24E18 = 2.56E18 x 60 = 1.5E18 incorrect

Homework Statement A net charge of 49 mC passes through the cross-sectional area of a wire in 12.0 s (a) What is the current in the wire? _4.1E-3_ A (b) How many electrons pass the cross-sectional area in 1.0 min? ______electrons Homework Equations I=Q/t The Attempt...

Homework Statement At the point of fission, a nucleus with 98 protons is divided into two smaller spheres, each with 49 protons and a radius of 6.38x10^-15 m. What is the repulsive force pushing these two spheres apart Hint: d ≠ the radius Homework Equations F= k (q1q2/d^2) The...

A diverging lens is used to form a virtual image of an object. The object is 88.0 cm in front of the lens, and the image is 44.0 cm in front of the lens. Determine the focal length of the lens. 1/f = 1/do + 1/di since do is 88cm infront of the lense, that would keep the 88 positive, and...

kinetic energy loss?? A 2850 kg car moving east at 8.0 m/s collides with a 3200 kg car moving east. The cars stick together and move east as a unit after the collision at a velocity of 4.86 m/s. (a) Find the velocity of the 3200 kg car before the collision. 2.06 m/s to the east (b) What...

the answer is .4397

OH GOSH! i can't believe i made that dumb of a mistake! haha i got the right answer! thank you for correcting my algebra!

is it .5 rather?

i don't understand how to find the "work" done A driver of a 7475 N car passes a sign stating "Bridge Out 25 Meters Ahead." She slams on the brakes, coming to a stop in 10 s. How much work must be done by the brakes on the car if it is to stop just in time? Neglect the weight of the driver, and...

A flight attendant pulls her 70.0 N flight bag a distance of 269 m along a level airport floor at a constant speed. The force she exerts is 32.0 N at an angle of 52.0° above the horizontal. (a) Find the work she does on the flight bag. _5299_J (b) Find the work done by the force of friction...
