Answer:
Acceleration is the rate of change in velocity.
Explanation:
For example if you were riding in a car the change in velocity which is defined as an speed in direction. So if you were in a car and the car went from 30 MPH to 40 MPH the speed of the car has accelerated giving you acceleration.
Answer:
It will take 9 hours
Explanation:
If a car travels 100 km per hour and 900 km is divided by 100 it will take 9 hours to travel.
Answer:
C
Explanation:
The density is what determines if it will float. Lower densities float, while higher densities sink. Density takes mass and volume into account.
Answer: No
Explanation:
Whenever light travelling on a straight line encounters obstruction, it diffracts and scatter.
Scattering of light occurs when light passes through a rough path or a diffused surface.
But in case of spectral diffusion, which is the fluctuation in spectroscopy as a result of time dependent frequency shifts.
Spectral diffusion occurs in particular molecules initiated by excessive excitation energy.
Fluctuation in frequency does not mean diffraction of light or particles
Therefore, spectral diffusion does not cause light to scatter.
