Answer:
Wedge
Explanation:
Scissors are a pair of wedges that are combined together.
The process of refraction of light occurs when light rays bends when travelling between media of different densities.
What is refraction of light?
Refraction of light is the bending of light rays or the change in the direction of light rays as it travels between media of different densities.
Light waves travel faster in media of less density than media of more density.
The change in density of the media makes light waves to be bend towards or away from the normal.
For example, when light travels from less dense air to more dense water, the light rays are bent towards the normal. However, when light rays travel from water to air, the light rays are refracted away from the normal.
In conclusion, refraction of light waves occur when light crosses the boundary of media of different densities.

Mirrors reflect meaning shows what would be seen if everything was turned around, therefore, it shows text backwards because if it is turned around, it is in reverse order.
Answer:
616.223684211 N
Explanation:
= Resistive force on the wheel = 115 N
F = Force acting on sprocket
= Radius of sprocket = 4.75 cm
= Radius of wheel = 25 cm
Moment of inertia is given by
Torque
Torque is given by
The force on the chain is 616.223684211 N
