A flashlight is shone on a mirror. As you move the flashlight to increase the angle of incidence of the light on the mirror, the angle of the reflection also changes. How does the angle of reflection change?
Answer:
the angle of reflection also increases
Explanation:
this is because the law of reflection states that the angle of incidence equals to the angle of reflection, thus, if the angle of incidence increases, angle of reflection should also increase, basically , think as if the angle of incidence is the same thing as the angle of reflection

Explain how neutrons enable a nuclear chain reaction to take place. (2)
Answer:
Explanation:
In addition to the 'daughter' products, two or three neutrons also explode out of the fission reaction and these can then collide with other uranium nuclei which are unstable so these cause further fission reactions. This is known as a chain reaction .

Answer:
C. Van der Waals forces
Hydrogen bonds
Metallic bonds
Ionic bonds
Explanation:
This list orders the types of forces from weakest at the top to strongest at the bottom. Van der Waals forces are relatively weak intermolecular forces, followed by hydrogen bonds which are stronger. Metallic bonds are even stronger, and ionic bonds are the strongest among the listed forces.
