Explanation:
The equation of grating is given by :
Here,
(a+b) is called grating element
N is the number of slits per unit length,
n is the order
is the wavelength of light used
is the diffraction angle
Here, we need to write the effect on the interference pattern produced by a grating if the number of slits per unit length is increased. If the number of slits per unit length increases, the grating element decreases such that the angle of diffraction increases. Hence, the interference pattern shrinks.
Noble gasses.
alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements).
The answer is "friction and air resistance" gravity does some of the work by keeping the object from floating away, but friction and air resistance does the biggest part. Friction is how rough the ground it meaning on tile, dirt, grass, etc... that would slow down the object and air resistance is the gravity pushing on the object also making it stop.
Hope this helps!
Answer:
1000 Kilograms
Explanation:
Force is equal to mass times acceleration so if the force is 3000 and the acceleration is 3 m/s^2 then all you need to do to find the mass is divide 3000 by 3 which gives you 1000
