- 2. A boy stands 10 m in front of a plane mirror . then be . . . - Socratic
Now,distance between the boy and his image is 7 +7 i e 14 meters So,the image moved to him by (20 −14) or 6 meters Alternatively, From the above discussion,clearly, v + u = x (let)= 2u So, x = 2u Or, dx dt = 2 du dt It means velocity of image should be twice than that of man's velocity,so if the man moves by 3m then the image will move to

- Question #87b82 - Socratic
See a solution process below: First, we need to determine how much was left before the man spent 20% We can rewrite this part of the problem as: 10200 is 80% of what? We are using 80% because he spent 20% so the man has 100% - 20% = 80% left "Percent" or "%" means "out of 100" or "per 100", Therefore 80% can be written as 80 100 When dealing with percents the word "of" means "times" or "to

- Question #914ea - Socratic
150 12 = 12 5 We can then divide 12 5m by 40 to find how much wall 1 man can complete in 1 day: 12 5 40 = 0 3125 So 1 man can complete 0 3125 meters of wall in 1 day To find out how much wall is completed per day in the 30 days we divide 600m by 30: 600 30 = 20 Therefore, the men completed 20 meters of wall per day
- What is the strongest power ever found? - Socratic
It depends on what do you mean by power In physics, "power" = "energy consumed" "time", which will be in "Watts" Like Saturn V produced about 41 MW of power The Fat Man used 84 TJ of energy in 10 microseconds (approx) So the we are talking about 8 4times10^19 Watts The Tsar Bomba , THE most powerful nuclear weapon ever detonated yielded about 10^22 Watts But these were man made
