The mass can be calculated by dividing the net force acting on an object by the acceleration of the object. When talking about net force, we use the units kilogram meter per second squared. This is also known as a Newton. The units for acceleration is meters per seconds squared, and the units for mass are kilograms.
destructive interference occurs when two or more waves combine to make a wave with a smaller amplitude C is your answer my friend :)
The match making one is Radiation is i think B and Convection i think is C and Conduction i think is A. I think 1 is radiation. Because radiation is transferred between objects or an empty space. Number 2 i think is conduction Because conduction is the transfer of thermal energy between to objects touching. Number 3 i also i think is radiation because radiation transfers between objects. Number 4 i also think is conduction because the spoon was touching a hot pot that was on the stove so then the thermal energy was transferred between the two objects touching. number 5 I think is convection because convection is the transfer of energy by the movement of a fluid, such as air or water. Number 6 i think is radiation because the snake is not touching the lamp and radiation goes all across spaces. Number 7 i think is convection because convection is the movement of a fluid, such as air or water. Hope this helps sorry its so long :)
Answer:
See explanation
Explanation:
To find out the electronic structure of each element, you must know the number of electrons it contains.
If you find that out(the number of electrons in the neutral atom of an element is the same as its atomic number). Then you arrange those electrons in such a way that the first shell has only two electrons and subsequent shells have eight electrons.
Look up the groups to which the elements belong in the periodic table All the elements are in group 1 so the last shell must have only one electron.
Answer:
0.52°
Explanation:
refractive index for blue light, nb = 1.640
Refractive index for red light, nr = 1.595
Angle of incidence, i = 30°
Let the angle of refraction for blue light is rb and the angle of refraction for red light is rR.
By use of Snell's law for blue light
By use of Snell's law for red light
The angle between the two beams, 
θ = 18.27° - 17.75°
θ = 0.52°
