HEY TANX FOR HELPING ME!!!why does this converge when you take the limitn-----∞
I have to find out if the given series is divergent or convergent (conditionally or absolutely).1.) (5^k + k) / (k! +3)2.) (-1)^k / √(k(k+1))3.) (tan^-1 k) / k^2Any help would be appreciated. Thanks.
If the distance from a converging lens to the object is less than the focal length of the lens, the image will be A. real, inverted, and larger than the object. B. real, inverted, and smaller than the object. C. virtual, upright, and larger than the object. D. vi...
A converging lens has a focal length of 27.0 cm. The object is placed so that a virtual image with a magnification of +2 forms.(A) Calculate the location of the object.I know that the from the magnification the Image distance is -2. Please show your work!
A stamp collector uses a converging lens with focal length 34 to view a stamp 19 infront of the lens.a) Where is the image located? behind the lens or in front of the lens?b) calculate the distance between the lens and the image. ans=43cmc) what is the magnification.need help o...
An object's distance from a converging lens is6.53 times the focal length.How far is the image from the lens? Express the answer in terms of the focal length.Answer in units of f .
)does this series converge or diverge and why?
An object is placed 20 cm from a first converging lens of focal length 12.8 cm. A second converging lens with focal length 21 cm is placed 10 cm to the right of thefirst converging lens. (Take the direction to the right to be positive.)(a) Find the position q1 of the image formed...
In the figure above a converging lens is located at the origin. It has a focal length of f1= 20.3 cm. An object is placed a distance a =25.3 cm to the left of the converging lens. In addition a concave mirror with focal length f2= 10.9 cm is located at L = 118.62 cm to the right...
A diverging lens (f = -11 cm) islocated 20.0 cm to the left of a converging lens (f =34.0 cm). A 3.00 cm tall object stands tothe left of thediverging lens, exactly at its focal point.(a) Determine the distance of the final imagerelative to the converging lens.1 cm(b) What is the...
A concave mirror and a converging lens lie on the same axis 105.0 cm apart with the lens to the right of the mirror. The converging lens has a focal length of 85.0 cmand the focal length of mirror is 10.0 cm. A candle is placed at the center of curvature of the mirror and it's vi...
