The work to its very best
Explanation:
More people reduces the time spent on one work which makes easier to finish but the work might not be done to its very best because different people are doing the job
Answer:
How is hydrogen obtained and separated from other nearby substances?
photoelectrolysis, a photoelectrochemical cell submerged in water uses sunlight to separate the water into hydrogen and oxygen bubbles. In the thermochemical cycle, water is heated to 800 to 1,000 °C, with the molecule. splitting to release hydrogen. The main drawback of this method is that it requires nuclear power
How is Hydrogen used?
Hydrogen can be used in fuel cells to generate electricity, or power and heat. Today, hydrogen is most commonly used in petroleum refining and fertilizer production, while transportation and utilities are emerging markets
What products are made from Hydrogen?
Hydrogen is a very useful element. It is used to make ammonia for fertilizers, refining metals, and methanol for making artificial material like plastics. Hydrogen is also used as a rocket fuel where liquid hydrogen is combined with liquid oxygen to produce a powerful explosion.
Any environmental concerns about the use of Hydrogen?
Emissions of hydrogen lead to increased burdens of methane and ozone and hence to an increase in global warming. Therefore, hydrogen can be considered as an indirect greenhouse gas with the potential to increase global warming.
An object moving in a circle wants to move in a straight line.
The motion of an object is tangent to the circle.
Tangential speed remains constant for an object with uniform circular motion.
Only the direction of the object changes, which means velocity is changing and the object is accelerating
Ok, let me see if I can help
Sound is caused by vibrations. These can pass through a solid, liquid, and gas. But not through vacuum because there are no particles
