A block with a mass m= 1.5 kg is resting on a wooden plank. The coefficient of static friction between the block and the plank is , = 0.58. One end of the board is attached to a hinge so that the other end can be lifted forming an angle 8, with respect to the ground. The x axis is along the plank. m Find an expression for the component of the force of gravity in the y direction, Fay, perpendicular to the plank in terms of given quantities and variables available. Write an expression for the magnitude of the friction force along the surface, in terms of the given quantities and variables given. Assuming the static friction is maximized, write an expression using only the given parameters and variables available for the sum of forces along the plank F. Write an expression for the maximum angle 0m, that the board can make with respect to the horizontal before it starts moving (Within terms of the given parameters and variables available) and use it to solve

to produce an image with a height of +10 cm when the object has a height of +1 cm, the magnification of an optical system must be?  a)+10 b)-10  c)0.1 d) -0.1

Identify the means by which you can use a converging lens to form a virtual image.

An object placed 15 cm to the left a convex lens produces and image 31 cm on right side of the lens. What is the focal length of this lens? Only numerical answer required. No need for units.

Question in the attachments

A 5.50 cm tall object is 24.0 cm from a concave mirror with f = 20.0 cm. Find the image height. (Mind your minus signs.) (Unit = cm) Academy of Science. All Rights Reserved. Search H Enter 65 hulu

3. Make an image with a convex lens and a concave lens when object is at C or at 2F. Show your drawing and write four qualities of the images formed.

Problem 96. Indicate the single lens type (converging or diverging) and object position that will lead to the following kind of images. If no single lens system can produce the particular image indicate that this is so. A) real, upright, enlarged image. B) huge image at "infinity". C) real, enlarged, inverted image. D) tiny inverted image very near the focal point. E) real, reduced in size, inverted image. F) virtual, reduced in size, upright image. G) virtual, enlarged, upright image. H) real, inverted image that is the same size as the object. I) virtual, enlarged, inverted image. Problem 97. You are handed a converging lens and you have a ruler. Describe two different simple ways to determine the focal length of this lens. Each way should involve making only one measurement.

(9) Please don't write on a paper. I can't understand handwritten. Kathrine places a 6.95-cm tall candle a distance of 36.5 cm from a concave mirror. What is the height of the image when the focal length of the mirror is 50.0 cm? a. -135.14 cm b. 36.50 cm c. 25.72 cm d. 3.70 cm

Draw image as well please.
