The unit conversion factors are always a power of ten. It is very easy to get different measurements quickly.
Answer:
the answer is C
Explanation:
the seafloor is spreading
Answer:
Q = - 1.5 x 10⁻¹² Coulomb
Explanation:
While in the neutral state, the charge on the piece of purple plastic must be zero. So the net charge is due to the charge of the extra electrons. Therefore,
Q = ne
where,
Q = net charge on piece of purple plastic = ?
n = No. of extra electrons on piece of purple plastic = 9.31 x 10⁶ electrons
e = Charge on one electron = - 1.6 x 10⁻¹⁹ Coulomb
Therefore,
Q = (9.31 x 10⁶)(- 1.6 x 10⁻¹⁹ Coulomb)
<u>Q = - 1.5 x 10⁻¹² Coulomb</u>
Number of rulings per centimeter for the grating 4.5 x 10^3 grooves/cm
Given:
wavelength of light = 635.00 nm
angle of first order = 38.0∘
To Find:
Length of slits marked on grafting
Solution: Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant
We use the grating equation dsinθ = mλ
d = mλ/sinθ
d = 1 x 635x10^-7 m/sin 38.0∘
d = 2189.6 x 10^-7 m
Thus the grating gauge is
1/d = 0.00045 x 10^7 = 4.5 x 10^3 grooves/cm
So, number of rulings per centimeter for the grating 4.5 x 10^3 grooves/cm
