Answer:

<h3>The answer is 20 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass = 24 g

density = 1.2 g/mL

We have

$volume = \frac{24}{1.2} \\$

We have the final answer as

Hope this helps you

A 5000-lb wrecking ball hangs from a 50-ft cable of density 10 lb/ft attached to a crane. Calculate the work done if the crane l

aniked [119]

Answer:

total work is = 52450 J

Explanation:

given data

mass = 5000-lb

density = 10 lb/ft

height = 50 ft

solution

as we will treat here cable and ball are separate

and

here work need to lift cable is

w = (10Δy )(9.8 y ) j

and

now summing all segment of cable

so passing limit Δy to 0

so total work need

= $\int\limits^{10}_0 {98y} \, dy$

= $[49 y^2]^{50}_0$

= 2450J

so lifting 5000 lb wrcking 50 m required additional 5000 + 2450

so total work is = 52450 J

A stream of water strikes a stationary turbine blade horizontally, as the drawing illustrates. The incident water stream has a v

bulgar [2K]

Answer:

F = 1908 N

Explanation:

GIVEN,

Incident water stream has a velocity = U = +18.0 m/s,

Exiting water stream has a velocity = V = -18.0 m/s.

Mass of water per sec : M / t = 53 kg /s

Change in velocity d v =18 m / s – ( -18 m / s)

= 36 m / s

Magnitude of the average force exerted on the water by the blade

F = ( M / t ) x dv

=( 53 kg /s ) x ( 36 m/s )

F = 1908 N

Which rational number could be graphed between 0 and 1?A number line going from negative 5 to positive 3 in increments of 1.Nega

vovikov84 [41]

In order to find which rational number is between 0 and 1, let's convert them into their decimal form:

$\begin{gathered} \text{negative one-half:} \\ -\frac{1}{2}=-0.5 \\ \\ \text{one}-\text{fourth:} \\ \frac{1}{4}=0.25 \\ \\ \text{three}-\text{halves:} \\ 3\cdot\frac{1}{2}=\frac{3}{2}=1.5 \\ \\ 1.75 \end{gathered}$

Looking at the numbers in their decimal form, we can see that the number between 0 and 1 is one-fourth, therefore the correct option is the second one.
