The efficiency of a machine indicates how well its input energy is converted to useful output energy or work. It is a major factor in the usefulness of a machine and is the fraction or percentage of the output divided by the input.
According to the Law of Conservation of Energy, the total output energy or work must equal the total input energy. However, some of the input energy does not contribute to the output work and is lost to such things as friction and heat.
Examples of machine efficiency include a lever, automobile, and perpetual motion machine.
Fresh water has a variety of different sources on Earth which includes rivers, lakes, streams, rain water, etc.
One of the fresh water sources is a Lagoon which is a permanent shallow body of water which is separated from the larger water bodies by a natural barrier such as reefs or islands.
Reportedly, almost <u>311 plant species</u> are found to be grown in the Atanasovsko Lake lagoon, out of which the Marsh samphire, reed, vicia and sea wormwood are a few to name.
Explanation:
Acceleration is the change in speed over a given time period
For this you will need to use the Pythagorean’s theorem
Drawing this out may help!!
If you draw it out, you will get a triangle with a hypotenuse that’s you need to find out.
So 50^2 + 75^2
Square root = 8.67 approx
So displacement is 8.67 metres
Answer:
It would remain the same on Earth (5-kg) but on the moon, it would be 1-kg
Explanation:
To discover the weight on the moon, we partition the weight on earth by the world's power of gravity, which is 9.81m/s2. This ascertains the mass of the article. When we have the article's mass, we can discover the weight by increasing it by the gravitational power, which it is dependent upon.
