In a potato race 20 potatoes are placed in a line at intervals of `4m e t e r s` with first potato `24m e t r e s` from the starting point. A constant is required to bring the potatoes back to the starting place one at a time. How far would he run in bringing back all the potatoes?

Text Solution

`D4 = AE + EA = 2EC = 2(24 + 12) = 2 x 36 = 72 m.`

Hence the total distance travelled by the contestant is 2480 m

In a potato race, a bucket is placed at the starting point, which is 5 m from the first potato, and the other potatoes are placed 3 m apart in a straight line. There are ten potatoes in the line (see Figure).A competitor starts from the bucket, picks up the nearest potato, runs back with it, drops it in the bucket, runs back to pick up the next potato, runs to the bucket to drop it in, and she continues in the same way until all the potatoes are in the bucket. What is the total distance the competitor has to run?[Hint : To pick up the first potato and the second potato, the total distance (in metres) rim by a competitor is 2 x 5 + 2 x (5 + 3)]

Two large conducting plates are placed parallel to each other with a separation d . An electron (-e ,m) starting from rest near one of the plates reaches the other plate in time t_(0) . Find the surface density on the inner surface.

Two large conducting plates are placed parallel to each other with a separation of d between them. An electron starting from rest near one of the plates reaches the other plate in time t. If e is the charge on the electron and m is its mass, then the surface charge density on the inner surface is

A potato at initial temperature T_(0) is placed inside a hot convection oven maintained at a constant temperature T_(1)(gt T-(0)) . Assume that the potato receives heat only because of convection phenomenon and the rate at which it receives heat is given as hA (T_(1) – T) where h is a constant, A is surface area of the potato and T is instantaneous temperature of the potato. Mass and specific heat capacity of the potato are m and s respectively. In how much time the potato will be at a temperature T_(2)=(T_(0)+T_(1))/(2) ? Assume no change in volume of the potato.

On the ground 100 stones are placed such that the distance between the 1 st and 2 nd is 1m , between 2nd and 3rd is 3m, between 3rd and 4th is 5m and so on.How far will a person have to travel to bring them one by one to the basket placed at the first stone if he starts from the basket

Rahul is a ten year old boy. He had purchased a packet of potato chips more than a month ago. Rahul opened the packet at the time but could eat only some of the potato chips from it. He then kept the open packet containing remaining potato chips on his book rack. He wanted to eat the remaining potato chips today. Just when Rahul was about to put these potato chips into his mouth, his elder sister Pavni, who is a student of class X entered the room. She found that these potato chips were giving unpleasant smell. When she put one potato chip in her mouth, it hat so unpleasant taste. Pavni took away the packet from Rahul and did not allow him to eat these potato chips. She threw away the potato chips into a dustibin. (a) What is given to the condition in which potato chips kept open for a considerable time give out unpleasant smell and taste? (b) Which chemical reaction is responsible for the soilage of potato chips kept exposed by Rahul for a considerable time? (c) What produces the unpleasant smell as well as unpleasant taste in potato chips? Explain. (d) With which gas the plastic bags containing potato chips are filled and then sealed by manufactures? How does it help? (e) What values are displayed by Pavni in this episode?

There are 8 equidistant points A, B, C, D, E, F, and H in the clockwise direction on the periphery a circle. In a time interval t a person reaches from A to C with uniform motion while another person reaches the point E from the point B during the same time interval with uniform motion. Both the Persons move in the same direction along the circumference of the circle and start at the same instant. How much time after the start, will the two persons meet each other? 4t b. 7t c. 9t d. never

A sound source S, emitting a sound of frequency 400 Hz and a receiver R of mass m are at the same point. R is performing SHM with the help of a spring of force constant K. At a time t = 0, R is at the mean position and moving towards the right, as shown. At the same time, the source starts moving away from R with some acceleration a. The frequency registered by the receiver at a time t = 10 s is 250 Hz. What is the time (in seconds) at which the corresponding registered frequency of 250 Hz was emitted by the source? [Given that (m)/(K)=(25)/(pi^(2)) and amplitude of oscillation = (100)/(pi) m, V_("sound") = 320 m s^(-1)]

In an L-R circuit connected to a battery of constant e.m.f. E switch S is closed at time t=0. If e denotes the magnitude of induced e.m.f. across inductor and i the current in the circuite at any time t. Then which of the following graphs shows the variation of e with i ?
