Answer:
A biotic factor is a living thing and has an impact on the environment whilst Abiotic factor is not a living thing but has an impact on the environment
Answer:
a) 15.78 mi/h/s
b) 7.105 m/s^2
Explanation:
a) It is given that speed changes from 0 to 60 miles per hour (mph)
Acceleration is equal to change in speed divided by time
mi/h/s
b)
1 mile/h = 0.45 m/s
Acceleration in m/s^2
m/s^2
Regular reflection is a reflection such that the the angle of reflection of the light is equal to the angle of incidence and it is on the opposite of the normal to the point of incidence. In a regular reflection the incident ray, the reflected ray and the normal to the reflection all lie in the same plane. Regular reflection happens if the reflection surface is very smooth.
Answer:
A concave lens is exactly the opposite with the outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses.
