Two students performed the same experiment separtely and each one of the recorded two readings of mass which are given below Correct reading of mass is 3.0g. On the basis of given data, mark the correct option out of the following statements

A

Results of both the students are neither accurate nor precise.

B

Results of student A are both precies and accurate.

C

Results of student B are neither precise nor accurate

D

Results of student B are both precise and accurate.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Average of readings of student,
`A=(3.01+2.99)/(2) = 3.00`
Average of readings of student,
`B=(3.05+2.95)/(2) = 3.00`
Average reading of both students A and B, is close to the correct reading hence both are accurate.
Readings of student A are close to each other ( differ only by 0.02) and also close to the correct value. Hence the reading of A are precise also. But readings of B are not close to each other ( differ by 0.1) and hence are not precise.

A student performs an experiment to determine how the range of a ball depends on the velocity with which it is projected. The "range" is the distance between the points where the ball lends and from where it was projected, assuming it lands at the same height from which it was projected. It each trial, the student uses the same baseball, and launches it at the same angle. Table shows the experimental results. |{:("Trail","Launch speed" (m//s),"Range"(m)),(1,10,8),(2,20,31.8),(3,30,70.7),(4,40,122.5):}| Based on this data, the student then hypothesizes that the range, R, depends on the initial speed v_(0) according to the following equation : R=Cv_(0)^(n) , where C is a constant and n is another constant. The student speculates that the constant C depends on :- (i) The angle at which the ball was launched (ii) The ball's mass (iii) The ball's diameter If we neglect air resistance, then C actually depends on :-
