A _______ is an object with at least one slanting side ending in a sharp edge, which cuts material apart.
Explanation
A wedge is an object with at least one slanting side ending in a sharp edge, which is used to cut or split material apart. Examples : Axes, knives, chisels, plough nall, s harpener, iron nails and pins (push pin).
Sounds travel faster through solids than _______?
Explanation
Sounds travel faster through solids than through both gases and liquids. Solids have a more rigid structure , allowing sound waves to propagate more efficiently and at a faster speed. Here's a comparison of sound speeds in different materials: Solids (e.g., steel): up to 5,960 m/s (13,140 ft/s) Liquids (e.g., water): up to 1,482 m/s (4,862 ft/s) Gases (e.g., air): approximately 343 m/s (1,125 ft/s)
The matter that sound travels through is called the?
Explanation
Sound travels through a physical medium , such as air, water, or solid objects. It is transmitted through the vibration of particles in the medium.
Which of the following is an example of compound machine?
Explanation
A compound machine is a machine that is made up of two or more simple machines. A bicycle, a crane, wheel borrow and scissors are examples of compound machines because they are made up of multiple simple machines , such as: Wheels and axles (simple machine: wheel) Pedals and levers (simple machine: lever) Gears and pulleys (simple machine: pulley) Inclined planes (simple machine: inclined plane)
Which type of machine is a bicycle and crane?

Explanation
A screw is a simple machine that is an inclined plane wrapped around a cylinder. It is used to fasten objects together , and it is used in: Fastening parts together Holding things in place Providing a secure grip Examples include: Wood screws (used in woodworking and construction) Machine screws (used in machinery and equipment) Self-tapping screws (used in plastic and metal) Bolts (used in heavy-duty applications) Lag screws (used in heavy construction) Deck screws (used in decking and outdoor construction) Drywall screws (used in drywall installation) Anchor screws (used in concrete and masonry)
Explanation
An inclined plane is a slanting surface connecting a lower level to a higher level. It is a simple machine that helps to lift or move loads to a higher position, and is commonly used in : Ramps Staircases Slides Ski lifts Hilly roads
