The volume of a container is reported as 3.49 ft3. what is the volume in units of in3?
Kobotan [32]

The volume in units of 6.03x10^3 in3

1ft = 12 inch

So to convert foot into inches we have to multiply by 12

The volume of container = 3.49ft^3

=3.49×12×12×12

= 6030.72 in^3

<h3>What is the volume of a container?</h3>

The amount of space a container encloses, or how much room is inside of it, is measured by its volume. The volume of a box can be calculated using this straightforward formula: volume V = L × W × H for a box with height H, width W, and length L.

Many different units can be used, however because of the way this formula is written, the volume would have length to the third power dimensions. For instance, if the container's measurements are given in metres, the capacity of the box will be given in metres squared, or m3.

A manufacturer of CD-ROM drives claims that the player can spin the disc as frequently as 1200 revolutions per minute.
Leya [2.2K]

a. 7.0 m/s

First of all, we need to convert the angular speed (1200 rpm) from rpm to rad/s:

\omega = 1200 \frac{rev}{min} \cdot \frac{2\pi rad/rev}{60 s/min}=125.6 rad/s

Now we know that the row is located 5.6 cm from the centre of the disc:

r = 5.6 cm = 0.056 m

So we can find the tangential speed of the row as the product between the angular speed and the distance of the row from the centre of the circle:

v=\omega r = (125.6 rad/s)(0.056 m)=7.0 m/s

b.  875 m/s^2

The acceleration of the row of data (centripetal acceleration) is given by

a=\frac{v^2}{r}

where we have

v = 7.0 m/s is the tangential speed

r = 0.056 m is the distance of the row from the centre of the trajectory

Substituting numbers into the formula, we find

a=\frac{(7.0 m/s)^2}{0.056 m}=875 m/s^2
