A room has dimensions `3 m xx4 mxx5m`. A fly starting at one corner ends up at diametrically opposite corner.
(i) What is the magnitude of its displacement
(ii) If the fly does not fly but walks, what is the length of the shortest path it can take.

Text Solution

Verified by Experts

The correct Answer is:
(a) `sqrt(74)` ft (b) component of the displacement vector are 7ft and 3ft
Displacement vector, ` vecr=7hati+4hati+3hatk,`

(a) Magnitude of displancement `sqrt(7^2+4^2+3^2), sqrt(74) ft`, (b)Component of the displacement vector are 7 ft, and 3 ft,.

Two metallic plate A and B , each of area 5 xx 10^(-4)m^(2) , are placed parallel to each at a separation of 1 cm plate B carries a positive charge of 33.7 xx 10^(-12) C A monocharonatic beam of light , with photoes of energy 5 eV each , starts falling on plate A at t = 0 so that 10^(16) photons fall on it per square meter per second. Assume that one photoelectron is emitted for every 10^(6) incident photons fall on it per square meter per second.

A trolley of mass 200 kg moves with a uniform speed of 36 km/h on a frictionless track. A child of mass 20 kg runs on the trolley from one end to the other (10 m away) with a speed of 4 ms^(-1) relative to the trolley in a direction opposite to the its motion, and jumps out of the trolley. What is the final speed of the trolley? How much has the trolley moved from the time the child begins to run?

Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m above the surface of the water and the fly at the end of the string rests on the water 3.6 m away from her and 2.4 m from a point directly under the tip of the rod. Assuming that her string (from the tip of her rod to the fly) is taut, how much string does she have out (see the given figure)? If she pulls in the string at the rate of 5 cm per second, what will be the horizontal distance of the fly from her after 12 seconds?
