Answer:
Acoustic microstreaming
Explanation:
Acoustic microstreaming is the swirling effect produced by water stream confined in a spaced of a periodontal pocket.
- It is the movement of water in a particular direction as a result of mechanical pressure within the fluid body.
- They are often used in dental procedures to remove particulates from the teeth.
- It mostly relies on the properties of sound waves to achieve this goal
Answer:
The speed of elephant must be 1.4 m/s.
Explanation:
Mass of the elephant, M = 2800 kg
Mass of sprinter, m = 77 kg
Speed of sprinter, v = 8.5 m/s
It is required to find the speed of elephant to have the same kinetic energy as that of sprinter. So,

So, the speed of elephant must be 1.4 m/s.
Answer:
9.07 x 10^-3 N/C
Explanation:
The mobility of electrons is defined as the ratio of drift velocity to the applied electric field.
Vd = 4.08 x 10^-5 m/s
Mobility = 4.5 x 10^-3 m/s
Let the electric field is E.
Mobility = Vd / E
E = Vd / mobility
E = 4.08 x 10^-5 / (4.5 x 10^-3)
E = 9.07 x 10^-3 N/C
Answer:
The above given statement represent the Newton;'s 3rd law of motion.
This describes that when two objects collides or interacts with each other, there occurs a pair of forces that directly acts on the two colliding objects. The force exerted on both the sides are of equal magnitude.
For example, there are two contrasting body named M and N, which collides with each other. This collision results in the occurrence of force acting on both the objects. The body M exerts a force on body N and similarly, the body N exerts a force on body M, and this two forces are equal in amount.
Runoff, rill,gully,stream,tributary, and river.
