- 2. A boy stands 10 m in front of a plane mirror . then be . . . - Socratic
D 6 The image formed in a plane mirror is as far behind the mirror as the object is in front of it, i e the distance between the object and the mirror u is the same as the distance between the mirror and the image v So,here,given u= 10 hence v=10 so distance between the image and the boy is u+v or 20 meters If the boy moves 3 meters towards the mirror,then, u=10-3 or 7 So,v =7 as well Now
- What is an oxymoron? + Example - Socratic
An oxymoron is a seemingly contradictory statement On the surface an oxymoron seems to be contradictory, for example, "Child is father of man" On first inspection how can a child be a father of man? Of course a child cannot but a child grows into an adult and may well become a father of a son Another example is "The King is dead, long live the King" Again this seems to be contradictory but
- A man is 1. 65 m tall and standing 28 m away from a tree . . . - Socratic
Assuming the man's eyes are at the very top of his head (which is closer than assuming they are at his feet): The height of the tree is tan(32^o)*28 + 1 65 " meters" (Never underestimate the value of a picture)
- Determine true velocity? - Socratic
I get that the wind comes from the south west quadrant, blowing at a speed of 3 mps (11 km h) from an angle of 34 degrees south of west The man walks northwards with the same speed as the wind So there is a component of the wind velocity that comes from the south in a speed of 6 km h He feels a breeze from the west, so there is also a component from the west In the case of the cyclist, I
- Question #05f5e - Socratic
a=4 24" "m s^2, " direction:downward" "while elevator is stops ,bathroom scale show only the weight of man " G=m*g=691" "N "The tension on cable is the sum of the man's and the elevator's weights " "Tension="G+G_("elevator") "When the elevator is accelerated downwards, there is an " "inertia force in the reverse direction " "This inertial force reduces the weight on the bathroom scale
- The weight of an object on earth varies directly with its weight on the . . .
The weight of an object on earth varies directly with its weight on the moon If a baby weighing 24 pounds on the earth only weighs 3 84 pounds on the moon, how much does a 194-pound man weigh on the moon?
- How many electrons in the nitrite ion, #NO_2^(-)#? - Socratic
(O=)N-O^- No of valence electrons: =2xx6+5+1=18 So around each atom (from left to right above), there are 6, and 5, and 7 valence electrons Because there are 7 valence electrons around the rightmost oxygen (i e 9 electrons in total including the inner shell electrons), this oxygen has a formal negative charge Of course there is a resonance isomer: ""^(-)O-N(=O) The neutral nitrogen atom
- A man starts at point A, somewhere on cartesian coordinate . . . - Socratic
A man starts at point A, somewhere on cartesian coordinate system He goes 4 units to the right and then he goes 6 units upwards Finally he makes an angle of 45° with the x-axis downwards to the left over a distance of 2 units
