A Forensic Anthropologist studies skeletal remains and gather information used to determine the individual's age at death, sex and physical condition.
Transverse wave = at right angles to the direction of the motion of the wave
in transverse wave medium particles will move perpendicular to the direction of motion of medium particles
they all are perpendicular to wave always
Longitudinal wave = back and forth in the direction of the motion of the wave
in longitudinal waves medium particles will move in the direction of wave and the motion is always in back and forth type
electromagnetic wave = alternating waves moving at right angles to each other
electromagnetic waves are combination of electric field and magnetic field which oscillates perpendicular to wave as well as they are perpendicular to each other
Conductors are substances that pass an electrical charge.
Semiconductors are substances whose electrical conductivity is lower than that of metals and greater than that of dielectrics.
Electricity nonconductors or insulators - in the terminology of Faraday - dielectrics (see). N. perfect does not exist; they represent only a large resistance to galvanic current and then different bodies in varying degrees (see Galvanic current), so that between poor and good conductors there are many bodies of average conductivity. N. The galvanic current is also the best insulators of static electricity. N. Heat or its bad conductors are at the same time electrical insulators (see Thermal Conductivity).
A dielectric (insulator) is a substance that is poorly conducting or not conducting at all. The concentration of free charge carriers in a dielectric does not exceed 108 cm-3. The main property of the dielectric is the ability to polarize in an external electric field. From the point of view of the band theory of a solid body, a dielectric is a substance with a band gap greater than 3 eV.
Answer:
A compass works by detecting and responding to the Earth's natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth's magnetic field.
Explanation:
Answer:
momentum=mass x velocity= 10 x 2 = 20kgm/s
