n object is placed 37.4cm in front of a diverging lens with a focal length of 18.1 cm. Please provide your answers in units of cm if necessary.    bookmark_border1.0p3a Find the image distance. Answer Updated 6 days ago   Show feedback   bookmark_border1.0p3b Is the image real or virtual?       Real       Virtual Updated 6 days ago   Show feedback   bookmark_border1.0p3c Suppose the object is brought to a distance of 10.3 cm in front of the lens. Where is the image now with respect to its previous location? (Note: Ensure the sign convention you use is consistent by treating all image distances on the object side of the lens as negative.) Answer Updated just now   Show feedback   bookmark_border1.0p3d How has the height of the image changed if the object is 84.2 cm tall? Answer

Can you draw a FBD and KD please!

If a 120- volt circuit feeds four 40-watt fluorescent lamps, what current (in amps) is drawn if the power factor is 0.912 0.33 0.68 1.21 3.3

How do you draw a diagram of the ruler and mass system in equilibrium identifying the anti-clockwise torque and clockwise torque? How do I calculate the anti-clockwise torque and the clockwise torque of the system with the ruler and the washers, does it come from the data in table 2? Please help, thank you!

A long, narrow steel rod of length 2.5000 m at 33.5°C is oscillating as a pendulum about a horizontal axis through one end. If the temperature drops to 0°C, what will be the fractional change in its period?

How long should a pendulum be in order to swing back and forth in 1.6 s?

LECTURE HANDOUT: REFRACTION OF LIGHT I. Review Each of the diagrams at right shows a ray incident on a boundary between two media. Continue each of the rays into the second medium. Using a dashed line, also draw the path that the wave would have taken if it had continued without "bending." Does the ray representing a wave "bend" toward or away from the normal when: the wave speed is smaller in the second medium? ⚫the wave speed is larger in the second medium? Faster medium Slower medium Slower medium Faster medium II. Qualitative applications of refraction A. Place a coin at the bottom of an empty can or cup. Look into the cup at the coin while your partner slowly moves the can away from you until you no longer see the coin. Now, keep your head steady while your partner gently pours water into the cup. 1. Describe your observations. Switch roles with your partner so that you each have a turn. Shown below are cross-sectional diagrams of the cup for when it was empty and when it was…

Problem Six. A 70 kg student in the figure balances a 1200 kg elephant on a hydraulic lift with diameter 2.0 m that is filled with oil which has a density of 900 kg/m³. How many 80 kg students would have to stand on the first piston in order to raise the elephant by 2.55 m? 80 kg 1200 kg 17.) (A) 5 (D) 8 (B) 6 (E) 9 (C) 7 Oil 2.0 m 5

In the accompanying figure, the rails, connecting end pieces, and rod all have a resistance per unit length of 4.52/cm. The rod moves to the left at v = 5 m/s. If B = 0.3 T everywhere in the region, what is the current in the circuit (a) when a = 6.5 cm? (b) when a = 4 cm?
