Virty [35]

Answer:

Step-by-step explanation:

Velocity of first Person v_1=450 ft/min

Velocity of second Person v_2=350 ft/min

Distance between them P=100 ft

Let x be the distance moved by 1 st and y be the distance moved by second person by the time 12:02 PM

In Triangle ABC

BC=350 t+450 t

BC=800 t

using Pythagoras

AC^2=AB^2+BC^2

AC^2=100^2+(800t)^2

differentiating with respect to time

2\times AC\times \frac{\mathrm{d} AC}{\mathrm{d} t}=2\times (800t)\times 800

\frac{\mathrm{d} AC}{\mathrm{d} t}=\frac{800^2\times t}{AC}

AC after 2 minute

AC=1603.121 ft

\frac{\mathrm{d} AC}{\mathrm{d} t}=\frac{800^2\times 2}{1603.121}

\frac{\mathrm{d} AC}{\mathrm{d} t}=\frac{64\times 10^4\times 2}{1603.121}

\frac{\mathrm{d} AC}{\mathrm{d} t}=798.44 ft/min

Question
Alekssandra [29.7K]

Answer:

d=7.8\ g/cm^3

Step-by-step explanation:

Given that,

The dimensions of a rectangular block = 4 cm x 2 cm x 1.5 cm

Mass, m = 93.6 g

We need to find the density of steel. We know that the density of an object is equal to the mass divided by volume. So,

d=\dfrac{m}{V}\\\\d=\dfrac{93.6}{4\times 2\times 1.5}\\\\d=7.8\ g/cm^3

So, the density of the steel is 7.8\ g/cm^3.
