Answer:
The magnitude of F₁ is 3.7 times of F₂
Explanation:
Given that,
Time = 10 sec
Speed = 3.0 km/h
Speed of second tugboat = 11 km/h
We need to calculate the speed
The force F₁is constant acceleration is also a constant.
We need to calculate the acceleration
Using formula of acceleration
Similarly,
For total force,
The speed of second tugboat is
We need to calculate total acceleration
We need to calculate the acceleration a₂
We need to calculate the factor of F₁ and F₂
Dividing force F₁ by F₂
Hence, The magnitude of F₁ is 3.7 times of F₂
Answer:
λ = 482.05 nm
Explanation:
The diffraction phenomenon and the diffraction grating is described by the expression
d sin θ = m λ
where d is the distance between two consecutive slits, λ the wavelength and m an integer representing the order of diffraction
in this case they indicate the distance between slits, the angle and the order of diffraction
λ = d sin θ / m
let's calculate
λ = 1.00 10⁻⁶ sin 74.6 / 2
λ = 4.82048 10⁻⁷ m
Let's reduce to nm
λ = 4.82048 10⁻⁷ m (10⁹ nm / 1 m)
λ = 482.05 nm
