relative frequency calculation

Find the weight (W 1 gf) of a solid in air using a hydrostatic balance as shown in figure belo..

Let u be the frequency of a wave. That is, the number of vibrations completed by a particle in one second is u . Time taken to complete u vibrations = 1 second. . But time taken to complete one vibration is defined as the time period of the wa..

Degree of dissociation ( a ) at a particular concentration c is related to the dissociation constant (..

This is the so-called secant law, and it is very useful in making preliminary calculations for a specific MUF. Strictly speaking, it applies only to a flat Earth and a flat reflecting laye..

Melde's fork is arranged such that transverse waves can be set up in the string, when it vibrates. The scale pan is removed from the string and its mass S is found in a balance. It is attached to the string again. The fork is made to vibrate by inserting the plug key and adjusting the contact scre..

Which of the following statement(s) is/are false? I. Data such as blood types (A, B, AB, O) can be organised into a categorical frequency distribution. II. Except for rounding errors, relative frequencies should add up to 100. III. A statistical device used in explorat..

Five dice were thrown 96 times and the number of times 4, 5 or 6 were shown are given in the table. Calculate c 2 . Number of dice throwing 4 or 5 or 6 5 4 3 2 1 0 Frequency 7 19 35 24 8 3 => 11.1 or 12.9 or 17.1 or 11.7..

Jeff used the relation v = i r to calculate the resistance, r , of a copper wire, where i is the current and v , the constant potential. Find the relationship between the current in the wire and the resistance of the wire. => Current in the wire is inversely proportional to the ..
