Assertion `:` In a movie, ordinarily 24 frames are projected per second from one end to the other of the complete film.
Reason `:` The image formed on retina of eye is sustained up to `1//10s` after the removal of stimulus.

A

If both the assertion and reason are true and reason explains the assertion.

B

If both the assertion and reason are true but reason does not explain the assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
When the movie is screened, the frames are displayed on after the other at the rate of `24` frames per second. The image of an object is formed on the retina. From where it is sent to the brain. If the object moves, the brain continues to show the old image for about one sixteenth of a second.

Read the statements given below. Identify and write the concept upon which the given statement is based. Identify and write the name of phenomenon that allows the image formed on retina to remain imprinted there for (1^(th))/(16) of a second after the object is removed from the front of the eyes.

A charge of 1 coul. is placed at one end of a non-conducting rod of length 0.6m. the rod is rotated in a vertical plane about a horizontal axis passing through the other end of the rod with angular frequency 10^(4) pi "radian/sec" . Find the magnetic field at a point on the axis ofrotation at a distance of 0.8 from the centre of the path. Now half of the charge is removed from one end and placed on the other end. The rod is rotated in a vertical plane about horizontal axis passing through the mid-point of the rod with the same angnlar frequency. Calculate the magnetic field at a point on the axis at a distance of 0.4m form the centre of the rod.

  • Assertion: If a body is dropped from the top of a twoer of height h and another body is thrown up simultaneously with velocity u from the foot of the tower, then both of them would meet after a time (h)/(u) . Reason: For a body projected upwards, the distance covered by the body in the last second of its upwards journey is always 4.9m irrespective of velocity of projection (g=9.8 m//s^(2))

  • Read the passage given below and answer the following questions: The transition metals when exposed to oxygen at low and intermediate temperatures form thin, protective oxide films of up to some thousands of Angstroms in thickness. Transition metal oxides lie between the extremes of ionic and covalent binary compounds formed by elements from the left or right side of the periodic table. They range from metallic to semiconducting and deviate by both large and small degrees from stoichiometry. Since d-electron bonding levels are involved, the cations-exist in various valence states and hence give rise to a large number of oxides. The crystal structures are often classified by considering a cubic or hexagonal close-packed lattice of one set of ions with the other set of ions filling the octahedral or tetrahedral interstices. The actual oxide structures, however, generally show departures from such regular arrays due in part to distortions caused by packing of ions of different size and to ligand field effects. These distortions depend not only on the number of d-electrons but also on the valence and the position of the transition metal in a period or group. Assertion (A): Transition metals form protective oxide films. Reason (R): Oxides of transition metals are always stoichiometric.

    A
    Assertion and reason both are correct statements and reason is correct explanation for assertion.
    B
    Assertion and reason both are correct statements but reason is not correct explanation for assertion.
    C
    Assertion is correct statement but reason is wrong statement.
    D
    Assertion is wrong statement but reason is correct statement.

    When researchers find a reasonably complete fossil of a dinosaur, they can determine the mass and weight of the living dinosaur with a scale model sculpted from plastic and based on the dimensions of the fossil bones. The scale of the model is 1/20, that is, lengths are 1/20 actual length, areas are (1//20)^(2) actual areas, and volumes are (1//20)^(3) actual volumes. First, the model is suspended from One arm of a balance and weights are added to the other arm until equilibrium is reached. Then the model is fully submerged in water and enough weights are removed from the second arm to reestablish equilibrium (Fig. ). For a model of a particular T. rex fossil 791.10 g had to be removed to a reestablish equilibrium . what was the volume of (a) the model and (b) the actual T . rex ? (c) if the density of T.rex was approximately the density of water , what was its mass ?

    Two metalic plates A and b has the same area of 5xx10^(-4)m^(2) are placed parallel to each other at a distance of 1 cm. Plate B carrins a positive charge of 33.7xx10^(-12)C . A monochromatic beam of light, with photons of energy 5eV each, starts falling on plate A at t=0 so that 10^(16) photons fell on it per square metre per second. Assume that one photoelectron is being emitted for every 10^(6) incident photons. Assuming that all the emitted photoelectrons are collected by plate b and th work function of plat A remains constant at the value 2 eV, the numbeer of photoelectrons emitted up to t=10 s is nxx10^(6) . Find the value of n. Negleect the time taken by the photoelectron to reach plate B. (Take epsilon_(0)=8.85xx10^(-12)C^(2)/N-m^(2) )

    The English alphabet is categorised into 5 groups, each starting with a vowel and encompassing the immediately following consonants in the group. Thus, the first group would have letters A, B,C and D, the second E, F, G and H, and so on. These groups are assigned values as 10 for the first, 20 for the second, and so on, up to 50 the last. Every letter in a particular group will have the same value of the group when used to form words. The value of each letter should add up to compute the value of the word. If the word has letters only from the same group, the value of the word would be the value of the letter multiplied by the number of letters in the word. However, if the letters in a word are from different groups, the value of the first letter of the word and any other letter of that group will be the same as that of its group, but that of the subsequent letter will he ‘double’ as much as the value of its group. For example: The value of ‘CAB’ will be 30 (i.e. 10 + 10 + 10 ) as all the three letters are from the first group, each one having a value of 10. The value of ‘BUT’ will be 10 + (50*2) + (40*2)= 190 The value of ‘JUNK’ will be 30 + (50*2) + 30 + 30 = 190 . Now, find out the value of each word in the following questions: HIGH 1) 40 2) 60 3) 70 4) 80 5) None of these
