The answer is C!!!XD
Hope this helped!!!XD
Also, can I get brainliest please? I only need 2 more:D
Answer: Option (C)
Explanation: Rock cycle plays an important role in the alteration of rocks from one form to another.
- Igneous rocks when undergoes high temperature and pressure condition, it transforms into a metamorphic rock.
- Sedimentary rocks are formed from the sedimentation and consolidation of sediments
- Igneous rocks are formed due to the crystallization of magma.
Hence the correct answer is option (C)
Answer:
Electromagnetic Radiation
Explanation:
Electromagnetic radiation is formed by the combination of electric and magnetic fields, which propagate through space in the form of energy-carrying waves.
Electromagnetic waves have vibrations perpendicular to the direction of wave propagation. For this reason, they are classified among the transverse waves.
Electromagnetic waves travel through space, and do not need a material medium to propagate.
Main types of electromagnetic radiation.
Gamma rays: More energetic radiation. It has the highest frequency (and therefore, the shortest wavelength). They constitute a form of radioactivity.
X-rays: Radiation of less energy than gamma rays. It is used in medical examinations and in the study of metals.
Ultraviolet (UV) rays: Radiation of less energy than X-rays. It comes mainly from the sun.
Visible radiation: Radiation of lower energy than ultraviolet rays. Collect the range of frequencies that can be perceived with the view, from red to violet.
Infrared rays (IR): Radiation of less energy than visible radiation. It is emitted by hot bodies.
Microwave: Radiation of less energy than infrared. It is used in appliances and medical therapy.
TV and radio waves: Less energetic radiation. They are used in telecommunications
Answer:
f(-9) = 184
Explanation:
f(x)=3x²+5x-14
f(-9)= 3(-9)² +5(-9)-14 Order of Operations : Exponents
= 3(81)+5(-9)-14
= 243+5(-9)-14
= 243-45-14
= 198-14
f(-9)= 184
Hope this helps :)
