Answer:
option (B) is correct.
Explanation:
frequency is directly proportional to the speed of wave and inversely proportional to the wavelength.
For string
frequency , f = v/λ
for tube
frequency ∝ 1 / λ
So, we can say that the frequency is inversely proportional to the wavelength.
thus, the higher the mode means shorter the wavelength.
The purpose of system is to make system more reliable and efficient for desired work completion
Explanation:
In most of the times, the system analysts operate in a dynamic environment where change is the necessary process . A business application, a business firm or a computer system may be the required environment. In order To rebuild a system, the key elements must be considered which we need to examine are as follows:
1. Outputs and inputs.
2. Security and Control.
3. processor
4. Environment.
5. Feedback.
6. Boundaries and interface.

Answer:
Mass attached to the spring is 41.95 kg
Explanation:
We have given time period of the spring T = 2.1 sec
Let the mass attached is m
And spring constant is k
We know that time period is given by
---------eqn 1
Now if the mass is increased by 68.10 kg then time period become 3.4 sec
So ------eqn 2
Now dividing eqn 1 by eqn 2
So mass attached to the spring is 41.95 kg
Answer:
bounced back at oncoming waves
____________________________________________________
If the incoming wave strikes a barrier at a 90 degree angle, the wave energy is, in fact bouncing back at oncoming waves.
