Answer: This is not easy lol
Explanation:
Answer: 4.675×10^-6 m
Explanation: this is a question under the pattern gotten from an interference experiment.
The formulae below defines the experiment given
y = Rmλ/d
Where y = distance between the center fringe and any other fringe in the pattern = 8cm = 0.08m
m = position of fringe = 1 ( this is because we have only one central band)
λ = wavelength of light used for experiment = 680nm = 6.8×10^-7m
d = width of slit =?
R = distance between slits and screen = 5.5 cm = 0.055m
By substituting the parameters, we have that
0.08 = 0.055 × 1 × 6.8×10^-7/d
By cross multiplying, we have that
0.08 × d = 0.055 × 1 × 6.8×10^-7
d = 0.055 × 1 × 6.8×10^-7/ 0.08
d = 3.74 × 10^-7/ 0.08
d = 46.75×10^-7
d = 4.675×10^-6 m
A compound is a combination of molecules. Molecules and formula units are made of two or more different types of atoms either ionically or covalently bonded.
Compounds are made with chemical bonds. can only separated by a chemical ways.
Mixtures are two or more types of elements that are NOT chemically bonded. and we can separated by a physical ways.
Answer:
Ay=v₂t + ½ gt² is the best choice to solve this problem.
The height of the cliff is = 176.4 meters.
Explanation:
Given,
initial velocity = 0m/s as it is dropped vertically
acceleration = g = 9.8 m/s²
time = 6s
Height =?
Using the equation Ay=v₂t + ½ gt², we can calculate Ay, which is the height.
So,
Ay=v₂t + ½ gt²
by substituting v, t, and g, we get:
Ay= 0 × 6 + ½ × 9.8 × 6²
Ay = 0 + 4.9 × 36
Ay = 176.4 m
