If R1 = 1000, R2=500, and R3=500, and the total current is 2A, how much is the total resistance? R3 8 Ry + O 10 0 O 20 0 O 30 0 40 0 Correct answer not foundBased on the figure below, how much is the current at R1 if the total voltage is 220V? 20.0 0 30.0 0 50.0 0 WW 12 R2 R3 90.0 0 R4 O 1 87 A 3.53 A 5.87A 703 A O Correct answer not foundWhen white light passes through a prism, it is divided into its color components. Which among the following is INCORRECT? Each ray bends towards the normal line at different degrees. The refractive index of the glass is different for each wavelength of light. a The different wavelengths separate out. The speed of light is retained as it passes through the prism An incident ray creates an angle of 30" with the surface of a plane mirror. What will be the angle measurement of the reflected ray? 60 10 45 30What happens to the speed of light as it travels to a material with greater value of index of refraction? The wave speed increases. 4 The wave speed doubles. The wave speed remains the same. The wave speed decreases All of the following changes due to refraction, EXCEPT:* direction of the ray O wave speed S O wavelength frequencyBased on the figure below, how much is R234? R 20.0 0 R1 3 30.0 0 50.0 02 R2 R3 90.0 9 R4 18 75 ohms O 42.35 ohms O 50 ohms 80 ohms Correct answer not found30 Which among the following is NOT TRUE about a wave's wavelength? it is the horizontal distance from crest to crest O it is always relative to the equilibrium it is an indication of energy O it is the vertical distance of a crest and a troughLight traveled from material A to material B with an incident ray of 60'. The refracted angle measures 49.3, Which among the following can be inferred about the two media? Material A has a refractive index that is less than one 2 Material B is denser than Material A Material B may enable total internal reflection Material A is denser than Material BReflection only happens in smooth surfaces. Which among the following describes this statement's validity? True. This enables the rays to bounce back as expected. True. This is evident in plane mirrors. False. Reflection happens only in a more dense material False. Reflection may happen in uneven surfaces. What is the frequency of a yellow light in vacuum if its wavelength is 580 nm? 5.17x10*14 Hz U O 1.93x10*14 Hz 517x10*15 Hz 1.93x10*15 HzWhich of the following is the correct description of the simplified circuit of the combination circuit below? The simplified circuit is a parallel circuit with resistors RI, R23 R4 and R5n. O The simplified circuit is a parallel circuit with resistors R123, R4, and R5. The simplified circuit is a series connection With resistors RI. R23, R4. and R5. O The simplified circuit is a series circuit with resistors RI and R2345
