Answer:
5.81 × 10⁻⁵ m
Explanation:
For constructive interference, the expression is:
d is the distance between the slits.
The formula can be written as:
....1
The location of the bright fringe is determined by :
Where, L is the distance between the slit and the screen.
For small angle ,
So,
Formula becomes:
Using 1, we get:
Given that:
m = 3, y = 47 mm (Location of the fringe)
Since,
1 mm = 0.001 m
y = 0.047 m
Given L =1.4 m
λ = 650 nm
Since, 1 nm = 10⁻⁹ m
So,
λ = 650 × 10⁻⁹ m
Applying the formula as:
⇒ d, distance between the slits = 5.81 × 10⁻⁵ m
Answer:
Two non-perpendicular vectors will not form a right triangle. Yet it is possible to force two (or more) non-perpendicular vectors to be transformed into other vectors that do form a right triangle. The trick involves the concept of a vector component and the process of vector resolution.
Answer:
Acceleration = a = -1.94 m/s^2
Explanation:
Weight of the bundle = W = mg
m = W/g = 473/9.8
m = 48.26 kg
There are two forces acting on the bundle such as tension in the upward direction and weight in the downward direction. So, according to newton’s second law of motion:
Sum of forces = ma
T - W = ma
a = (T – W)/m
a = (379 - 473)/48.26
a = -1.94 m/s^2
Negative sign shows that the acceleration is in the downward direction.
I think that they are called meteorites
