Two wires, A & B of the same material are set to have current passing through. If voltage has the same value for both wires, which among the following is NOT VALID if wire A has a smaller cross-sectional area than B? Wire A will have greater resistance than wire B O Wire A will have lesser conductivity than wire B Wire A has the same resistivity as wire B Wire A will heat up faster than wire BWhich among the following is TRUE about an EM wave? * it can only travel in vacuum it can only travel through matter it does not change its speed in different medium it can travel in both in vacuum and through matter Why was it hard to see your reflection after you crumpled up an aluminum foil? O Only some intensity of the light is reflected, thus making it hard to see ourselves. )The reflected ray of the light will be different from the angle of incidence The light is reflected in varying directions, making it hard for us to see ourselves The ray of light will bounce back along the incident ray therefore no image will be O formedWhich among the following quantities can be expressed in s^-1?* Frequency Energy 3 Period Wave speed What is the index of refraction of a liquid if the light passing through it travel at 1.8x10*8 m/s? O 0 60 1.36 O 1:67 Q 212Light passes through material A to material B at an angle of 45' and refracts at an angle of 31 from the normal line. If the index of refraction of material A is 1.53, what is the index of refraction of material B? 0.48 0.90 1.11 2,10 Which among the following statements is TRUE regarding the Electromagnetic Waves? Radio waves have longitudinal type of wave. O Infrared is the color red light that we see in a rainbow. UV rays carry a relatively lesser energy that Gamma rays. Microwaves are used in thermal imaging and night vision cameras.What is the refractive index of a material with a speed of light in that material is approximately 1.24x1048 m/s? 2.42 O 0.41 O 1.33 O 25Which among the following clearly distinguishes the type of current flow as shown in the illustration? 1/-1 O The one on the left shows an electron flow while the one or the right shows a conventional flow The one on the left implies a direct current while the one on the right implies an alternating current The one on the left shows a conventional flow while the one on the right shows an electron flow O Time one on the left implies an alternative guirent while the one on the right implies a direct currentIf resistors 1, 2, and 3 have a resistance of 100 each and the total voltage is 30V, what is the current at 13? O 0.33 A 0 66 A 100 A 1 33 ABased on the figure below, how much is the total current if the total voltage is 110V? 20.0 1 R1 30.0 0 50.0 9 5 WW R2 R3 90.0 $2 R4 177 A 3 53 A 587 A 703 A O Correct answer not found
