Calculate the time it takes for the car to reach the beginning of the hill given that acceleration as already found in part a is 2.89 m/s²
Answer:
5.88 s
Explanation:
Using kinematic equation, v=u+at where v and u are the final and initial velocities respectively, a is acceleration and t is time.
Considering the first part, acceleration is already found as 2.89 m/s and the final velocity is given as 17 m/s while the initial velocity is zero since it is at rest.
Making t the subject of formula then
t=(v-u)/a
Substituting the given figures then
t=(17-0)/2.89=5.8823529411764s
Rounded off, t=5.88 s

Answer:
d = 1.82 10⁻⁶ m = 1.82 μm
Explanation:
The diffraction phenomenon is explained by a similar equation Young's double slit equation
d sin θ = n λ
Where d is the spacing between the bars, θ is the angled diffraction, n in an integer representing the order of diffraction and λ is the wavelength of light
Let's calculate
d = n λ / sin θ
d = 1 470 10⁻⁹ /sin 15
d = 1.82 10⁻⁶ m = 1.82 μm
