At an Electronic Data processing unit, five out of the eight program sets P,Q,R,S,T,U,V and W are to be operated daily. On any one day, except for the first day of a month, only three of the program sets must be the ones that were operated on the previous day. The program operating must also satisfy the following conditions: 1. If program P is to be operated on a day, V can’t be operated on that day. 2. If Q is to be operated on a day, T must be one of the programs to be operated after Q. 3. If R is to be operated on a day, V must be one of the programs to be operated after R. 4. The last program to be operated on any day must be either S or U. If the program sets R and W are to be operated on the first day, which of the following could be the other program on that day?
The following sentences form a paragraph. The FIRST and SIXTH sentences of the paragraph are given. The rest of the sentences are numbered as B, C, D, ad E, which are not in proper order. Read the sentences and place them in chronological order. National Solar Mission is one of the eight missions set up of National Action Plan on Climate change (NAPCC) that was released on 30 June 2008. With this ambitious target, India will become one of the largest Green Energy producers in the world, surpassing several developed countries. Government stepped up India’s solar power capacity target under the Jawaharlal Nehru National Solar Mission (JNNSM), by five times, reaching 1,00,000 MW by 2022. The target will principally comprise 40 GW Rooftop and 60 GW through Large and Medium Scale Grid Connected Solar Power Projects. The new targets were approved in June 2015. During recent times with improvement in technology and scaling up production capacities, solar energy has become cost-competitive and targets seem to be more viable now.
In a solar operated steam power plant, water is converted into steam via solar heat. If the effective area of solar plate is 200m2, value of solar constant is 1.362KW per m2, efficiency of solar components is 17% and overall thermal efficiency of steam cycle desired is 12%. Find the turbine power output?
Statement 1 – The length of the day is slowly increasing. Statement 2 – The dominant effect causing a slow down in the rotation of the earth is the gravitational pull of other planets in the solar system.
According to Griffith theory, which of the following are true for the fracture stress in a brittle material?
P. Increases with increasing surface energy
Q. Decreases with increasing elastic modulus
R. Decreases with increasing length of pre-existing crack
S. Decreases with increasing number of pre-existing cracks of same size
What are the limitations of solar energy? 1. Collecting solar energy over large areas and converting it to other forms that can be conveniently transported, stored and used in existing equipment is not economical 2. Low density of solar energy as compared to coal, oil and gas 3. Its major applications are photothermal conversion, solar water heating, green housing technology and photo voltaic conversion Select the correct answer using the codes given below:
With reference to technologies for solar power production, consider the following statements: 1. 'Photovoltaics' is a technology that generates electricity by direct conversion of light into electricity, while 'Solar Thermal' is a technology that utilizes the Sun's rays to generate heat which is further used in the electricity generation process. 2. Photovoltaics generates Alternating Current (AC), while Solar Thermal generates Direct Current (DC). 3. India has a manufacturing base for Solar Thermal technology, but not for Photovoltaics. Which of the statements given above is/are correct?

Select the correct differences between char and varchar data types? i. varchar is non unicode and char is unicode character data type ii. char is ‘n’ bytes whereas varchar is actual length in bytes of data entered in terms of storage size iii. varchar is variable in length and char is the fixed length string iv. For varchar, if a string is less than the maximum length then it is stored in verbatim without any extra characters while for char if a string is less than the set length it is padded with extra characters to equalize its length to given length
