Energy efficiency = useful energy output/total energy input x 100(%)
If a power plant uses 100 units of energy to create electricity and the output is 5 units, where does the 95% of the energy input go?
A: Lost as heat
B: Lost as gas
C: Escapes the system as potential energy
Answer:
no
Explanation:
No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance

What is DNA?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

The other participants received a placebo. Both groups received counseling on lifestyle modification. At the end of the 56 weeks, the bodyweight of each participant was determined. Which of the following best the question that was being investigated in the study? a. Can body mass index affect the onset of diabetes? b. Is liraglutide effective for weight loss? c. What effect does Liraglutide have on diabetes? d. How does lifestyle modification counseling affect body weight?
Once identified the controlled, the independent, and the dependent variables, we can say the question is B) Is liraglutide effective for weight loss?
To answer this question, what we need to do first is to identify the variables involved in the experiment.
What are the variables involved in an experiment?Dependent variables
These are the variables whose response depends on any change in the independent variable.
Independent variablesThese are all the variables in an experiment that provoke a response in another variable. They are modified in the experiment to analyze how another variable responds to it.
Controlled variableControlled variables are kept constant in an experiment. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.
In this experiment we can also identify two groups. The experimental group and the control one. Both groups are composed of individuals coming from the same population.
What is the control group?The control group is used to identify any factors other than the modified variables of the treatment that might influence the results obtained in the study.
What is the experimental group?This group gets the treatment to observe how the independent variable affects the individuals.
In the experiment,
Control group ⇒ receives placeboExperimental group ⇒ receives liraglutideindependent variable ⇒ liraglutidecontrolled variables ⇒ lifestyle modification, participants did not have type 2 diabetes mellitus.dependent variable ⇒ bodyweight of each participantAccording to the identification of the variables, the question that was being investigated in the study is option B) Is liraglutide effective for weight loss?
