An electron gun fires electrons into a magnetic field directed straight downward. Find the direction of the force exerted by the field on an electron for each of the following directions of the electron’s velocity: (a) horizontal and due north; (b) horizontal and 30° west of north; (c) due north‚ but at 30° below the horizontal; (d) straight upward. 2. (a) Find the direction of the force on a proton moving through the magnetic fields in Figure 1‚ as shown. (b) Repeat part (a)‚ assuming the moving

A ball is thrown upward at time t=0 from the ground with an initial velocity of 18 m/s (~ 40 mph). Assume that g = 10 m/s2. Time to reach apex 18/10 = 1.8 Time x 2 = 3.6 Great height reached by ball – (Velocity)(time)+(-5)(time^2) 18x1.8+(-5)(1.8^2)=16.2 A model rocket accelerates upward from the ground with a constant acceleration‚ reaching a height of 63 m in 8 s. * Speed at height 63 - 2x63/8 = answer What is the acceleration= answer/8 * If you were to drop a rock from a tall building

FORCE AND MOTION Scalars vs. Vectors Scalars | Vectors | A scalar quantity has only magnitude. | A vector quantity has both magnitude and direction. | Scalars can be added‚ subtracted‚ multiplied and divided just as ordinary numbers‚ i.e.‚ scalars are subjected to simple arithmetic operations. | Vectors cannot be added‚ subtracted and multiplied following simple arithmetic laws. Arithmetic division of vectors is not possible at all. | Example: mass‚ volume‚ time‚ distance‚ speed‚ work‚ temperature

Summary: Experiment 9 is conducted to identify the importance of intermolecular forces and how they affect molecules. Intermolecular forces are forces between molecules that determine whether the molecule is a solid‚ liquid‚ or gas under standard conditions. In our lab‚ we measured the maximum and minimum temperature reached and time it took to reach it of alcohols and alkanes. In addition‚ we measured the vapor pressure of the liquid at different temperatures. Through Experiment 9‚ we concluded

Matt Ennis 10/3/10 The Use of Force A physician is summoned to make a housecall on a family with who he has had no prior contact. He quickly sizes up the situation: the household is poor but clean; the patient is a female child whose parents are nervously concerned‚ dependent on‚ yet skeptical of the doctor. The child ’s beauty and piercing stare make an immediate impression on him. Concerned that diphtheria may be the cause of illness‚ he uses his customary professional manner

The Five Forces Framework and Competitive Strategy In this framework due to Michael Porter there are two high-level stages in the creation of competitive strategy‚ each stage corresponding to a high-level determinant of profitability mentioned in the previous section. The first stage is the assessment of the attractiveness of the industry in which a given company is embedded based on a structural analysis of the industry. In this stage‚ called the five forces framework‚ five forces that influence
