<span>The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.</span>
The angle of the Sun above the horizon, which is the solar altitude, influences the intensity ofsolar radiation received at Earth’s surface. At the place on Earth where the Sun is directlyoverhead, the local solar altitude has its maximum value of 90 degrees and solar rays are mostconcentrated. Whenever the Sun is positioned lower in the sky, solar radiation spreads over alarger area of Earth’s horizontal surface and thus is less intense. Solar radiation reaches theplanet essentially as parallel beams of uniform intensity. The nearly spherical Earth presents acurved surface to incoming solar radiation so that the noon solar altitude always varies withlatitude. The intensity of solar radiation actually striking Earth’s atmosphere is greatest at thelatitude where the noon Sun is in the zenith and decreases with distance north and south of thatlatitude. Decreasing solar altitude lengthens the path of the Sun’s rays through the atmosphere.As the path lengthens, the greater interaction of solar radiation with clouds, gases and aerosols<span>reduces its intensity</span>
Scientists believe that thesolar system<span> was </span>formed<span> when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.</span>
Answer:
Explanation:
First, the instant associated to the angular displacement is:
Roots of the second-order polynomial are:
Only the first root is physically reasonable.
The angular velocity is obtained by deriving the angular displacement function:
The angular acceleration is obtained by deriving the previous function:
The resultant linear acceleration on the rim of the disk is:
Answer:
C. the C horizon likely has a rockier texture than the topsoil and subsoil.
Explanation:
because i did it on study island
