I think it is 7 in the first row and 6 in the second. I am very sorry if wrong :D
Answer:
D. 15 m/s downward
Explanation:
v = at + v₀
v = (-9.8 m/s²) (1.5 s) + (0 m/s)
v = -14.7 m/s
Rounded to two significant figures, the answer is D, 15 m/s downward.
Answer:
Explanation:
7.0g is 
the acceleration due to gravity.
Given that 
, acceleration can be calculated as:
Since circular motion is involved and our radius of curvature is given as,
, <em>centripetal acceleration </em>is given by the formula:
.
Make 
subject of the formula to find 
:
The maximum speed of the pilot is 
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
