The stopwatch used by a student to measure velocity of a pulse in a slinky was of least count 0.1 second. He stops the stopwatch
sweet-ann [11.9K]

Least count of the pulse stopwatch is given by

\Delta t = 0.1 s

this means each division of the stopwatch will measure 0.1 s of time

After 3 journeys from one end to other we can see that total time that is measured here is shown by the clock as 52nd division

So here total time is given as

Time = (Number of division) (Least count)

now we will have

T = 52 \times 0.1s

T = 5.2 s

The area of an equilaterla triangle is increasing at a rate of 5 m^2/hr. find the rate at witch the height is chganging when the
Lena [83]

The rate at which the height is changing is ( 5 / x ) m / hr

We know that,

Area of an equilateral triangle A = \sqrt{3} x^{2} / 4

h = \sqrt{3} x / 2

Where,

x = Side

h = Height

Given that,

dA / dt = 5 m^{2} / hr

h = \sqrt{3} x / 2

Differentiate both sides with respect to t

dh / dt = ( \sqrt{3}  / 2 ) ( dx / dt )

dx / dt = ( 2 /  \sqrt{3} ) ( dh / dt )

A = \sqrt{3} x^{2} / 4

Differentiate both sides with respect to t

dA / dt = ( \sqrt{3} / 4 ) ( 2x ) ( dx / dt )

5 =  ( \sqrt{3} / 4 ) ( 2x ) ( 2 /  \sqrt{3} ) ( dh / dt )

dh / dt = ( 5 / x ) m / hr

Rate of change of height is defined as the rate at which height of an object changes with respect to time. It is represented as dh / dt

Therefore, the rate at which the height is changing is ( 5 / x ) m / hr
