I would let someone more confident in this field to answer this question but that sounds like a Chemical reaction
For a curved mirror, all points have the same normal and the angle of incidence is also equal to the angle of reflection.
According to the laws of reflection, the incident ray, reflected ray and normal all lie on the same plane. For a curved mirror, the normal remains the same at all points along the curved mirror.
Again, the angle made between the incident ray and the normal is the same as the angle made between the reflected ray and the normal. Therefore, the angle of reflection is equal to the angle of incidence.

Answer:
G. 93 m
Explanation:
Applying the equation of motion,
s = ut + 1/2at²........................ Equation 1
Where s = distance, u = initial velocity, t = time, a = acceleration.
Given: u = 0 m/s ( at rest), a = 3.3 m/s², t = 7.5 s.
Substitute into equation 1
s = 0(7.5) + 1/2(3.3)(7.5)²
s = 0 + 185.625/2
s = 185.625/2
s = 92.8
s ≈ 93 m
Hence the right option is G. 93 m
Answer:
1.49 m/s
Explanation:
The average speed is:
Where v is speed, s is distance and t is time. We are given with a distance of 18 km and time is 3.36 hours.
We'll be converting from km to meters and hours to seconds as standard unit for speed is m/s.
To convert the unit from kilometer to meter, we know that 1 kilometer equals to 1000 meters. Therefore, 18 kilometers will equal to 1000 * 18 meters which will equal to 18000 meters total.
To convert from hour to second, we know that 1 hour equals to 60 minutes. Therefore, 3.36 hours will equal to 60 * 3.36 = 201.6 minutes.
A minute equals to 60 seconds. Therefore, 201.6 minutes equal to 60 * 201.6 = 12096 seconds.
Finally, we have units in meter and second. We'll be able to calculate for average speed now by applying the formula above:
Therefore, Serina's average speed will be around 1.49 m/s
