.
im not the best with physics but i think its right
Answer:
when the mass of an object is decreased, the acceleration will increase
when mass is increased, acceleration decreases
Answer:
The wavelength is 0.14 m
Explanation:
Given that,
Frequency = 2450 Hz
Speed of sound = 343 m/s
We need to calculate the wavelength
Using formula of wavelength

Where, v = speed of sound
f = frequency
Put the value into the formula



Hence, The wavelength is 0.14 m
Answer: High frequency, short wavelength.
Explanation:
Photons have high energy.
