Answer:
336.78 cubic feet
Explanation:
total volume= volume of cuboid + volume of cylinder
= lxbxh + π r^2h
= 9x7x4 + 3.14x(3)^2 x3
= 252+ 84.78
= 336.78 cubic feet
Answer:
The Law of the Conservation of Energy
Explanation:
The Energy Conservation Act tells us that any form of energy changes from one form to another. And that you can never have a higher amount of energy than you originally got. That is, if you have 100 [J] of energy to be transferred as heat from one medium to another, only 100 [J] can be used to be transferred, no amount greater than this value can be transferred.
The particular study of Energy Transfer in the form of heat is important in sciences such as thermodynamics and heat transfer.
The correct answer is:
That the land where it specifically was has been moving and that years ago that place was under water.
Explanation:
Kansas has been the cause of some of the most luxurious fossil findings in US history. The fossil record of Kansas spans from the Cambrian to the Pleistocene. From the Cambrian to the Devonian, Kansas was coated by a shallow sea.
Answer:
a) Emission
b) Reflection
c) Absorption
d) Transmission
Explanation:
a) The screen of computers (most of them LED or LCD) are a bunch of tiny lights that take power of our pc to produce light so they EMMIT light.
b) Sun's light contains all the visible colors of electromagnetic spectrum, when sun light hits an object, due their chemical characteristics the object absorbs a bunch of wavelengths and reflects others, the reflected light is the color we perceive with our eyes. So, for a banana, it absorbs almost all the other colors and reflects only yellow light.
c) As explained on b) a banana absorbs all the other colors except yellow so blue is absorbed on it.
d) When a light hits transparent medium, some rays are reflected and other passes through the medium so that rays are called transmitted and that is the case of Sunlight passing through a glass door.
