If the charge of a point source is 0.500 C, then the electric field strength at 1 point a distance of 0.250 m from the point source is O 8.99 x 109 N/C O 1.80 x 1010 N/C O 4.50 x 1010 N/C O 7.19 x 1010 N/CA star produces a natural visible colour with a frequencv of 51?l THE (5.1? x 1 point 10"14 Hz]. What is the wavelength of the light in nanometers (rim)? nm [Just enter the number in the answer spot, vou don't need to include units.) Your answer A star produces a natural visible colour with a frequencv of 5.1? x10"14 Hz. 1 point If from earth the star appears to have a visible colour with a frequencv of 4.92 x 16AM Hz, what colour does the star appear to be on earth and is the star moving towards or awav from the earth? 0 Blue and moving away from earth 0 Blue and moving towards earth 0 Orange and moving towards earth 0 Orange and moving away from earth The total resistance provided by some 3.50 O speakers connected in 1 point parallel is 1.1? Q. How many speakers are connected? [Round to the nearest whole number). Your answer Use the following information to answer the next question. Strings of small, colourful lights are often used for holidayr deoorating and other occasions. An inexpensive string of hose lights consists of 50 LED bulbs connected in series. The resistance of each bulb is 150 D. The total resistance provided by the bulbs is 0. {Just enter the number 1 point in the answer spot, you don't need to include units.) Your answer Scientists have theorized that a long conducting wire attached to the International Space Station would generate electrical energy. Space Station with Conducting Wire Attached 1 point To generate electricity using a long conducting wire, the space station must be _i relative to a ii field. The statement above is completed by the information in row Row ii A stationary magnetic B moving magnetic C stationary gravitational D moving gravitationalIf the power consumed by a 4.00 0 speaker is 160 W, then the current that 1 point flows through the speaker is 0 0.0250 A If a stereo operates at a maximum power of 160 W for 2.00 hr, then the 1 point electrical energy:F consumed is 0 0.0222 .J O 1.151(10'6J A 6.74 x 10^22 kg planet in space is 9.11 x 10^5 m from a moon orbiting it. In 1 point N/kg, what is the gravitational field strength of the planet on the moon? N/kg (Just enter the number in the answer spot, you don't need to include units.) Your
