The following data gives the information on the observed lifetime (in hours) of 225 electrical components : Determine the modal lifetimes of the components.

The following table givesthe information on the observed lifetimes(in hours) of 215 electrical components. Determine the modal lifelines of the components.

What is the information conveyed by the following observations :Atom is electrically neutral.

The following data gives the distribution of total monthly household expenditure of 200 families of a village. Find the modal monthly expenditure of the families. Also, find the mean monthly expenditure :

The following frequency distribution gives the monthly consumption of electricity of 68 consumers of a locality. Find the median, mean and mode of the data and compare them.

The following data was recorded for values of object distance and the corresponding values of image distance in the experiment on study of real image formation by a convex lens of power +5 D.One of these observations is incorrect.Identify this observation and give reason for your choice: .

The integrated rate equations can be fitted with kinetic data to determine the order of a reaction. The integrated rate equations for zero, first and second order reactions are : Zero order : [Al =-kt+ [A]_0 First order : log [A] = -(kt)/2.303 + log [A]_0 Second order : 1/([A])=kt+1/[A]_0 These equations can also be used to calculate the halt life periods of different reactions, which give the time during which the concentration of a reactant is reduced to half of its initial concentration, i.e, at time t_(1//2), [A] = [A]_0//2 Answer the following (1 to 5) question : For a second order reaction, rate at a particular time is x. if the initial concentration is tripled, the rate will become

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : In electric circuits, wires carrying currents in opposite directions are often twisted together. Reason : If the wires are not twisted together, the combination of wires forms a current loop, the magnetic field generated by the loop, might affect adjecent circuits or components.

In these question, a statement of asertion followed by a statement of reason is given .Choose the correct answer out of the following choices: Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion. Assertion is correct statement but reason is wrong statement. Assertion is wrong statement but reason is correct statement. Assertion:the pairs E_x,B_y nd E_y,B_x ,components of space and time varying electric field overset vec (E) and magnetic field oversetvec(B) can generate a plane electromagnetic wave travelling along the Z-direction. Reason:It is because,electromagnetic waves propagae in the direction of vectro overset vec E xx overset vec B .
