State what causes tides on earth

Answer:

a) Kinetic energies

K₁ = 1.2 J

K₂ = 7.5 J

b) The bullet that has the highest kinetic energy is the one with the highest speed , v = 50 m/s , K₂ = 7.5 J

c) K₂ -K₁  = 6.3 J

Explanation:

The kinetic energy (K) is that due to the movement of a body and is calculated as follows:

K = (1/2) m*v²  (J)

Where :

m : the mass of the body ( kg)

v is the speed of the body (m/s)

Data

m₁ = m₂ = 0.006 Kg

v₁ = 20 m/s

v₂ = 50 m/s

a)Calculation of the kinetic energy

K₁ = (1/2) (m₁)*(v₁)²

K₁ = (1/2) (0.006)*(20)²

K₁ = 1.2 J

K₂= (1/2) (m₂)*(v₂)²

K₂ = (1/2) (0.006)*(50)²

K₂ = 7.5 J

b) K₂ ˃ K₁

The bullet that has the highest kinetic energy is the one with the highest speed , v = 50 m/s, K₂ = 7.5 J

c) Difference of their kinetic energies (K₂ -K₁)

K₂ -K₁  = 7.5 J - 1.2 J = 6,3 J

Answer:Eddy current inspection.

Explanation:EDDY CURRENTS are currents which are produced as a result of changes observed within the magnetic field of an electric circuits. Eddy currents are also called Foucault's Currents. Eddy currents can heat up objects without actually coming in contact with that object.

Eddy current testing or inspection ( ECT) is an electromagnetic testing/inspection methods applied in nondestructive testing (NDT).

Nondestructive testing utilises

Electromagnetic induction to detect and describe surface and sub-surface issuess in conductive materials according to the features of the issues or problems in the conductive material.

Answer:Eddy current testing method.

Explanation:

Non destructive testing methods are techniques which makes use of electromagnetic radiation to examine and detect anomalies in a wide variety of articles( metallic or non - metallic) without causing any changes to it. Non destructive testing is used in science and technology fields such as:

- petroleum engineering,

-mechanical engineering,

- forensic engineering,

- aeronautical engineering and

- medicine.

Types of non destructive testing includes

Eddy current testing, magnetic- particle testing, liquid penetrant testing, radiographic testing, ultrasonic testing, and visual testing.

Eddy current testing method is used to detect surface or near surface defects in most metals, and may also be used to separate metals or alloys and their heat-treat conditions.
