Efficiency is defined as the measure of the amount of work or energy is conserved in a certain process. At all times, in every process, work or energy is always lost or wasted due to certain interference. Not all work given is converted to useful work or energy. Thus , efficiency is calculated by dividing the energy or work output to the energy or work input then the value is multiplied by 100 to express efficiency as percentage.
Efficiency = work output / work input Efficiency = (1540 J / 1600 J) x 100= 96.25%
Thus, the answer is B.
Answer: Option (d) is the correct answer.
Explanation:
When two or more different substances are mixed together then it results in the formation of a mixture.
Mixture are of two types, that is, homogeneous mixture and heterogeneous mixture.
In homogeneous mixture, the constituent particles are distributed evenly throughout the mixture.
Whereas in heterogeneous mixture, the constituent particles are non-uniformly distributed.
Thus, we can conclude that mixtures are classified based on the distribution of particles in them.
Answer:
There are 120 possible ways.To calculate the number of permutations here, where order is important and repetition is not allowed, we use the following formula:Number of permutations = n! / (n - r)! = 5!/0! = 12345 / 1 (note: "!" means "factorial" and 0! equals 1) = 120/1 = 120.For a complete list see below. Let a,b,c,d & e represent the 5 players and their order determine their position:{a,b,c,d,e}
Explanation:
Answer: Carbonic acid occurs naturally in the body and performs important regulatory functions.
Explanation: Carbonic acid (
) is an acid formed from the carbon dioxide present in the body. It is also known as the respiratory acid as it helps in the transport of carbon dioxide in the body.
With the help of enzyme Carbonic Anhydrase, carbon dioxide is converted into carbonic acid. This acid is an unstable intermediate which gets dissociated into bicarbonate ions (
) and
ions. immediatley.
Therefore, Carbonic acid performs important regulatory functions in the body.
