- On December 27, 2004, astronomers observed the brightest flash of light ever recorded from outside of our solar system. It came from a highly magnetic neutron star SGR 1806-20 (also know as a magnetar). During the 0.20 s burst, this star released as much energy as our sun would over a period of 250,000 years. If our sun outputs approximately Psun = 3.846x 1026 W, what was the average power output of this magnetar in terms of Psun?You are standing 4.0 m from a 200-W lightbulb. If the pupil of your eye is a circle 8.0 mm in diameter, how much energy enters your eye per second?The image attached is a neat copy of a photo of an electricity meter for a domestic solar array. The display shows the energy we sold to the electricity company on a winter's day. Each box is 100 W high and 1 hr wide. At the radius of the earth's orbit, the intensity of sunlight is I=1.4 kW.m–2 . (This means that 1.4 kW.m–2 passes through 1 square metre at right angles to the sun's rays.) The solar array in the previous question consists of 10 panels, each with area A=1.6 m2 . Under optimal conditions - with the sun at right angles to the array and no clouds in the sky - the array produces Pout=2.3 kW . What is the efficiency of the array? Power out/power in = _____ %.

The beam is nearly a cylinder 2.3x10-3 m in radius and it travels in free space. ▼ Determine the energy delivered in each pulse. Express your answer to two significant figures and include the appropriate units. AU = Submit Part B Erms = Submit Value Provide Feedback μA Determine the rms value of the electric field. Express your answer to two significant figures and include the appropriate units. Request Answer O ■ μA Value Units Request Answer ? Units ?Let's try a few more examples that relate power and energy. A certain high-efficiency LED light bulb has a power output of 9.20 W. That is, 9.20 J of electric energy is converted to electromagnetic (light) energy and radiated away every second. How much energy is output by the lightbulb if it is left on for a total time of 7.50 hours? In this case, we're relating power to energy change, so we simply use the relationship E t P = Here, instead of work W, we use in the equation E, which is the amount of energy output or converted in the amount of time t. From this, what do we find the total energy output in joules to be? 33120 X x Solve the above equation for the energy E in terms of power P and time t. Remember that 1 W = 1 J/s, so to find the energy in joules, convert the time to seconds first. There are 60 minutes in one hour and 60 seconds in one minute. J

In one section of the production process, the bars must slide down a plane inclined at an angle θ = 21.0° to the horizontal. It has been found that the bars travel with too high a speed and become dented or bent when they arrive at the bottom of the plane and must be discarded. In order to prevent this waste, you devise a way to deliver the bars at the bottom of the plane at a lower speed. You replace the inclined plane with a pair of parallel metal rails, shown, separated by a distance ℓ = 2.00 m. The smooth bars of mass m = 1.00 kg will slide down the smooth rails, with the length of the bar always perpendicular to the rails. The rails are immersed in a magnetic field of magnitude B, and a resistor of resistance R = 1.00 Ω is connected between the upper ends of the rails. Determine the magnetic field necessary in your device so that the bars will arrive at the bottom of the plane with a…
- pps51 please dont copy existing answers or i will dislike your answer thanksHigh-speed flash photography was pioneered by Doc Edgerton in the 1930s, while he was a professor of electrical engineering at MIT. You might have seen examples of his work in the amazing shots of hummingbirds in motion, a drop of milk splattering on a table, or a bullet penetrating an apple . To stop the motion and capture these pictures, one needs a high-intensity, very short pulsed flash, as mentioned earlier in this module. Suppose one wished to capture the picture of a bullet (moving at 5.0×102 m/s ) that was passing through an apple. The duration of the flash is related to the RC time constant, τ . What size capacitor would one need in the RC circuit to succeed, if the resistance of the flash tube was 10.0 Ω ? Assume the apple is a sphere with a diameter of 8.0×10–2 m.In a particular city, electrical energy costs $0.13 per kilowatt-hour. (Round your answers, in dollars, to at least two decimal places.) (a) How much does it cost to operate an old-style incandescent 40.0-W light bulb continuously for 24 hours? $ (b) A modern LED light bulb that emits as much visible light as a 40.0-W incandescent only draws 4.50 W of power. How much does it cost to operate this bulb for 24 hours? $ (c) A particular electric oven requires a potential difference of 220 V and draws 20.0 A of current when operating. How much does it cost to operate the oven for 4.30 hours? $
