Answer:
Wave speed is the distance a wave travels in a given amount of time, such as the number of meters it travels per second. Wave speed is related to wavelength and wave frequency by the equation: Speed = Wavelength x Frequency. This equation can be used to calculate wave speed when wavelength and frequency are known

<span>pH is the measure of acidity/alkalinity of a substance. A pH of 7 is considered is neutral. Less than 7 is the acidic pH, with 1 being most acidic. Thus a vegetable with a pH of 5.3 is slightly acidic. A ph of 4.6-6.9 are called as low acidic foods. Thus, the vegetable is low-acidic.</span>
Answer: it is (A)

A negative feedback mechanism tries to negate changes so as to restore the variations that occurs in the value of a parameter or system.
<h3>What is Negative feedback?</h3>
This is known to be a method that tend to reverses any kind of movement or deviation from the set point and it then keeps the body parameters to its normal range.
Note that A negative feedback mechanism tries to negate changes so as to restore the variations that occurs in the value of a parameter or system.
