Lina20 [59]

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

Suppose an elephant has a mass of 2800 kg. show answer No Attempt How fast, in meters per second, does the elephant need to move
Mumz [18]

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,

K_e=K_s\\\\\dfrac{1}{2}MV^2=\dfrac{1}{2}mv^2\\\\MV^2=mv^2\\\\V=\sqrt{\dfrac{mv^2}{M}} \\\\V=\sqrt{\dfrac{77\times 8.5^2}{2800}} \\\\V=1.40\ m/s

So, the speed of elephant must be 1.4 m/s.

The drift speed in a copper wire is 4.08 × 10-5 m/s for a typical electron current. Calculate the magnitude of the electric fiel
jeka94

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

For every action there is an equal and opposite reaction. What does these words mean in physics?
Ne4ueva [31]

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.
