Juror #3 is very biased against the 19-year-old boy that is being tried‚ and this affects all of his thoughts and actions regarding the case. He has this bias because his own son hit him in the jaw and ran away from home at the age of 15: “I’ve got a kid…when he was fifteen he hit me in the face…I haven’t seen him in three years. Rotten kid! I hate tough kids! You work your heart out [but it’s no use] (21)

Other major types of microscopes are the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscope. Microscope 1. An optical instrument‚ consisting of a lens‚ or combination of lenses‚ for making an enlarged image of an object which is too minute to be viewed by the naked eye.

omission was deliberate or unintentional due to cultural bias? The women in the drawings done by white men placed ignorance on the detail of women at the treaty signing due to the cultural standards of women in their society. Many white cultures felt that women where highly lower in standards compared to men‚ so there placement at the ceremony was of no importance. I do feel that the omission of the women was in fact deliberate. The bias against women in white culture‚ especially because they

images. When using a converging lens‚ it’s helpful to remember these rules of thumb. If the object is very far away‚ the image will be tiny and very close to the focal point. As the object moves towards the lens‚ the image moves out from the focal point‚ growing as it does so. The object and image are exactly the same size when the object is at 2F‚ twice the focal distance from the lens. Moving the object from 2F towards F‚ the image keeps moving out away from the lens‚ and growing‚ until it goes to

accommodation of the eye? Ans. The ability of the eye lens to adjust its focal length‚ so as to clearly focus rays coming from distant as well a near objects on the retina‚ is called the power of accommodation of the eye. Q2. A person with a myopic eye cannot see objects beyond 1.2 m distinctly. What should be the type of the corrective lens used to restore proper vision? Ans. A person with a myopic eye should use a concave lens of focal length 1.2 m so as to restore proper vision

Chapter 14 Outline I. Refraction of Light A. Refraction is the bending of light at the boundary of two media. 1. It is caused by differences in the way light travels in the two media a) Light changes speed unequally. (1) One side of the light becomes slower/faster 2. If light is perpendicular to the new medium‚ light will not refract a) If the media have the same index of refraction‚ light will not refract B. Index of Refraction 1. How well light travels through a medium is measured by

A ground breaking new tool used to study the heavens was introduced in the 17th century. This tool was known as the telescope. It revealed the cosmos in a different way than our naked eye could ever perceive. The telescope opened doors to countless stars‚ nebulae‚ galaxies‚ and a slew of never before seen wonders. With its creation came limitations and caused the need to improve and upgrade the methods in which the telescope functioned and find new ways of viewing the heavens.There are three main

Make sure there are no air bubbles. 7. Make sure the lowest power lens (the shortest lens) is in place over the stage. Place the slide onto the stage of the microscope. 8. Look through the eyepiece and turn the coarse focus knob (the largest knob) until an image comes into focus. It should look like scattered blobs. Move the slide

to allow more or less light. It is typically a plastic disk located between the light source and the specimen mount. The compound microscope has two systems of lenses for greater magnification‚ 1) the ocular or eyepiece lens that one looks into and 2) the objective lens‚ or the lens closest to the object. A microscope works by using lights‚ mirrors‚ and glass to magnify. The mirrors and glass bend the light in a certain way that it makes small objects appear larger. Method Procedure 1.2 Handling
