Hello!
A force of 5 N produces an acceleration of 2 m/s2 on the object. What is the mass of the object ?
Data:
F (force) = 5 N
m (mass) = ?
a (acceleration) = 2 m/s²
Solving:
Answer:
2.5 kg

Answer:
A.
Explanation:
it's needed top release energy due to the breaking of chemical bonds.
As the train blows its whistle towards you, the wavelength is shorter than the sound of the whistle at rest.
<h3>What is wavelength?</h3>
Wavelength is the distance traveled by a wave in a given period of time.
Relationship between wavelength, speed and frequency of sound
v = fλ
where;
- v is the speed of the sound
- f is the frequency of the sound
- λ is the wavelength of the sound
As the frequency of the sound increases, the wavelength of the sound decreases.
Thus, as the train blows its whistle towards you, the wavelength is shorter than the sound of the whistle at rest.
