Answer:
Their densities are different as well
Explanation:
Density is worked out by dividing mass by volume. If the mass was the same then the densities would be as well. But it's not.
How many marks is this question?
Answer:
work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force. actually, both of them give same meaning
Answer: 13.2678 kg
Explanation: Well, 13.2678 kg is 29.25 in mass and kg.
To solve this problem, we will apply the concepts related to the kinematic equations of linear motion, which define speed as the distance traveled per unit of time. Subsequently, the wavelength is defined as the speed of a body at the rate of change of its frequency. Our values are given as,



Velocity of the wave,



Wavelength of the wave,




Therefore the wavelength of the waves on the string is 11.53 cm
