Four successive members of the first series of the transition metals are listed below. For which one of them the standard potential (E_(M)^(0)2 + // m) value has a positive sign?

A ball is projected vertically up from ground. Boy A standing at the window of first floor of a nearly building observes that the time interval between tha ball crossing him while going up and the ball crossing him while going down is 2s. Another boy B standing on the second floor notices that time interaval between the ball passing him twice, during up motion and down motion is 1 s. Calculate the difference between the vertical positions of boy B and boy A (Assume , acceleration due to gravity , g=10 m//s^2 )

Radioactive decay is a statisticle process i.e., we cannot precisely predict the timing of a particular radioactivity of a particular nucleus . The nucleus can disintegrate immediately or it may take infinite time . Simply the probability of the number of nuclei being disintegrated at any instant can be predicted . the rate at which a particular decay process in a radioactive sample is directly proportional to the number of radioactive nuclei present and thus obeys first order kinetics . the factor dN/N expresses the fraction of nuclei decayed in time dt. t_(1//2) is the time in which half of the atoms are decayed and average life is the time for the nucleus to survive before decay . Which of the following relation is correct ? (t_(1//2) and t_(3//4) are time required to complete half and 3/4 decay respectively )

The first element of a group differes from its congeners, i.e other members of the group in many ways. These difference may be due to the following i) Small size of atom and ion ii) High electronegetivity iii) Non-availability of low lying d-orbitals The first element of a group shows resemblance with the second element of the adjacent group on the right. This is known as diagonal relationship Metal (M)+ N_(2) rarr "Nitride" underset("hydroysis")overset(H_(2)O)rarr NH_(3) . Metal (M) can be

A freshly prepared radioactive source of half period 2 hour emits radiations on intensity which is 64 times of the permissible safe level. The minimum time after which it would be possible to work with this source is :
