What does a negative angular acceleration indicate to you? Negative angular velocity(ω) means that the particle is revolving anticlockwise. Thus, negative angular acceleration(α) is a “push” in the anticlockwise direction. If α and ω have the same sign, the body will speed up, else slow down (and eventually go in reverse). Is clockwise positive or […]
Which cell has highest efficiency?
Which cell has highest efficiency? Scientists have developed a solar cell that is capable of converting direct sunlight into electricity with 44.5 percent efficiency — making it, potentially, the most efficient solar cell in the world. Current solar technology only converts electricity with a maximum efficiency of about 25 percent. Which metal is used to […]
How much forest is cut down for agriculture?
How much forest is cut down for agriculture? Rainforests across the world are in great danger. Food and Agriculture Organization’s 2016 State of the Forests report revealed that 7 million hectares of forest are lost annually while agricultural land expands by 6 million. Does agriculture affect rainforest? Agricultural use of some rainforest land proves to […]
Does higher entropy mean more stable?
Which gas is highly compressible?
Which gas is highly compressible? Gases are compressible because most of the volume of a gas is composed of the large amounts of empty space between the gas particles. At room temperature and standard pressure, the average distance between gas molecules is about ten times the diameter of the molecules themselves. How much work is […]
When electrons are being shared between atoms it is called a n?
When electrons are being shared between atoms it is called a n? A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, […]
What is the formula for calculating efficiency?
What is the formula for calculating efficiency? The formula to calculate work efficiency is the ratio of output to input expressed as a percentage. The work efficiency formula is efficiency = output / input, and you can multiply the result by 100 to get work efficiency as a percentage. How do you calculate the maximum […]
What is diode resistant?
What is diode resistant? Hence, diode resistance can be defined as the effective opposition offered by the diode to the flow of current through it. Ideally speaking, a diode is expected to offer zero resistance when forward biased and infinite resistance when reverse biased. What is the reverse resistance of a diode? Reverse resistance is […]
What is the impedance of RL circuit?
What are the major organs and functions of the nervous system?
What are the major organs and functions of the nervous system? The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. What is […]
