Identify the simple machines/other descripted in the following:
1:What is A structure or machine that has blades or sails which converts the wind’s Kinetic energy into mechanical or electrical energy
2: What is a weight that is suspended which can swing freely
3: What is the force that attracts a body toward any other physical body having mass.
Please answer ASAP.
clearly you haven't read the material.
Take a look at the definitions or descriptions of
turbine, pendulum, gravity
Sorry , i’m answering a test on which i was not given any knowledge on. For the gravity question is just the result of my stupidity
I find it hard to believe you are tested on material not presented earlier...
in any case, there is always google.
sounds more diagnostic than advanced.
In any case, it clearly discovered some areas in your education which need reinforcement.
Sure! Here are the answers to the questions along with an explanation of how we can identify each item:
1. The structure or machine that converts wind's kinetic energy into mechanical or electrical energy is called a wind turbine. It is considered a simple machine called a "wheel and axle." To find the answer, we can recognize that wind turbine blades or sails are designed similarly to the blades of a fan or a propeller, which are part of a wheel and axle mechanism. Additionally, wind turbines convert the wind's kinetic energy into rotational motion to generate electricity or perform mechanical tasks.
2. The weight that is suspended and can swing freely is called a pendulum. It is based on the simple machine called a "lever." To identify this, we observe that a pendulum is typically a mass (weight) attached to a string or rod, suspended from a fixed point. The mass swings back and forth due to the force of gravity acting on it. This swinging motion follows the principles of a lever, where the mass acts as the load, the fixed point is the fulcrum, and the force of gravity provides the effort.
3. The force that attracts a body toward any other physical body having mass is called gravity. Gravity is not classified as a simple machine but rather a fundamental force in nature. To identify this, we can relate the description to the concept of gravity itself. Gravity is the force that pulls objects toward each other due to their mass. It keeps us grounded on Earth, and it governs the motion of celestial bodies like planets and moons.
Remember, the best way to get accurate answers is by carefully reading and understanding the descriptions provided.
