Question

3. Define the term 'phase'.
4. If Y=4 Sin (5t). Give values of amplitude & angular velocity.
5. What is dimensional formula for specific heat?​

Answer 1

Answer:

3=In the physical sciences, a phase is a region of space, throughout which all physical properties of a material are essentially uniform. Examples of physical properties include density, index of refraction, magnetization and chemical composition.

4=Amplitude= 4, angular velocity=5

5=The specific heat of a substance (per unit of mass) has dimension L2·Θ−1·T−2, or (L/T)2/Θ. Therefore, the SI unit J/K/kg is equivalent to meter squared per second squared per kelvin (m2 K−1 s−2).
