P lease help me out wiyh one

Two loud speakers are driven by an oscillator. The sound you hear is quite loud. As I move one speaker toward you, you hear the sound first become softer and then become loud again. The distance I have moved the speaker is equal to 1 wavelength. 2 wavelength. 1/2 wavelength. The nucleus 8635Br is radioactive. It decays to 8636Kr and emits an electron. position. alpha particle. none of these. If a particle is accelerated, its de Broglie wavelength increase. remains the same. decreases. An object is accelerated from rest to some velocity v near the speed of light. If we calculated the energy required using the theory of special relativity, we would obtain result than if we calculated the energy required using classical Newtonian mechanics. the same a smaller a larger A drinking glass is floating in a larger container of water. I have an iron weight. In which of the following two cases will the water in the larger container rise the most? I put the weight into the floating glass. (The glass remains floating after the iron weight is put into it.) I put the weight directly into the water. Both of these will cause the water to rise the same amount. Which ray diagram best describes the refraction of light from glass (n = 1.5) into water (n = 1.33)? A B

Explanation / Answer

31)A)1 wavelength as max and min both occuring

32)A)electron can be seen by balancing

33)C)decreases

34)A)energy remains same ,frequency changes

35)B)as volume will be more displaced as more weight is inside water

36)B)away from normal frm denser to rarer
