Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 22 cm apart. The sound

intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 61 cm

Answer:

Negative interference

Explanation:

Thinking process:

In the physics, the interference is when there is either an additive or destructive effect in the effects of sound. In the first scenario, the sound is loudest when the speakers are separated at 22 cm apart. This is as a result of constructive interference. Constructive interference results from the additive effect of waves to give the highest pitch.  However, as the speakers are moved further, the sound decreases. This is because of the destructive interference where the waves are not much of addition.

Complete the ray diagram and label incident ray, refracted ray, angle of incidence, and angle of refraction ​
Novay_Z [31]

Answer:

Solution

verified

Verified by Toppr

(a) The labelled diagram is shown.

(b) The refractive index of diamond is 2.42. Refractive index of diamond is the ratio of the speed of light in air to the speed of light in diamond.i.e.,

μ=  

Speedoflightindiamond

Speedoflightinair

​

 

and, the ratio of these velocities is 2.42. i.e., This means that the speed of light in diamond will reduce by a factor of 2.42 as compared to its speed in air. In other words, the speed of light in diamond is  

1/2.42

times the speed of light in vacuum.

Explanation:

a) Draw and label the diagram given :

  (i) Incident ray

  (ii) Refracted ray

  (iii) Emergent ray

  (iv) Angle of reflection

  (v) Angle of deviation

  (v) Angle of emergence

(b) The refractive index of diamond is 2.42. What is the meaning of this statement in relation to speed of light?

Answer:

force F = 1.66 × 10^{-13} N

Explanation:

given data

proton and an electron = 865 nm

solution

we get here force that is express as

force F = k q1 q2 ÷ r²      ......................1

put here value and we get

force F = 9 × 10^{9} × \frac{1.6\times (10^{-19})^{2}}{865 \times (10^{-9})^{2}}    

force F = 1.66 × 10^{-13} N

ycow [4]

Answer:

60-100

Explanation:

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.
