Using the count data and observational data you acquired, calculate the number of CFUs in the original sample
Answer:
Doppler effect, the apparent difference between the frequency at which sound or light waves leave a source and that at which they reach an observer, caused by relative motion of the observer and the wave source. This phenomenon is used in astronomical measurements, in Mössbauer effect studies, and in radar and modern navigation.
Explanation:
Answer:
5 cm .
Explanation:
Wave length of sonar waves λ = 1390 / 512
= 2.715 m
For waves getting reflected from both layers of the coating , undergoing phase reversal , net change will be zero .
For destructive interference
path diff = ( 2n+1) λ / 2
2μt = ( 2n+1) λ / 2
2 x 13.5 x t = ( 2n+1) λ / 2
for minimum thickness
n = 0
2 x 13.5 x t = λ / 2
2 x 13.5 x t = λ / 2
t = λ / (2 x 27)
= 2.715 / 2 x 27
= .05 m
5 cm .
Gases have more kinetic energy than liquids. Liquids have more kinetic energy than solids. When a substance increases in temperature, heat is being added, and its particles are gaining kinetic energy. Because of their close proximity to one another, liquid and solid particles experience intermolecular forces.
Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This is normally taken as the definition of inertia.
