A bin has a volume of 1.5m^3, what is its volume in ft^3?

Physics
1 answer:
il63 [147K]3 years ago
6 0

Answer:

1.5m^3=1.5\times 3.28^3ft^3=52.931ft^3

Explanation:

We have given volume V = 1.5m^3

We have to convert this volume into ft^3

We know that 1 m = 3.28 feet

So for converting  1.5m^3  to ft^3 we have to multiply 3.28^3 to 1.5

So 1.5m^3=1.5\times 3.28^3ft^3=52.931ft^3

So in cubic meter 1.5 will be equal to 82.923 cubic feet

On dry concrete, a car can decelerate at a rate of 7.00 m/s2 , whereas on wet concrete it can decelerate at only 5.00 m/s2 . Fin
MariettaO [177]

Answer:

Explanation:

a ) Let the distance required in former case be d₁ .

initial velocity u = 30 m /s , final velocity v =0 , deceleration a = 7.00 m /s²

v² = u² - 2 a s

0 = 30² - 2 x 7 x d₁

d₁ = 64.28 m

b) initial velocity u = 30 m /s , final velocity v =0 , deceleration a = 5.00 m /s²

v² = u² - 2 a s

0 = 30² - 2 x 5 x d₂

d₂ = 90  m

c)

t = .5 s

s₁  = ut - .5 at²

= 30 x .5 - .5 x 7 x .5²

= 15 - .875

= 14.125 m

t = .5 s

s₂  = ut - .5 at²

= 30 x .5 - .5 x 5 x .5²

= 15 - .625

= 14.375  m

The​ half-life of a certain radioactive substance is 12 hours. There are 19 grams present initially. a. Express the amount of su
neonofarm [45]

Answer:

(a) N=19\times e^{-\lambda t}

(b) 15 hours

Explanation:

half life, T = 12 hours

No = 19 g

(a) Let N be the amount remaining after time t.

Let λ be the decay constant.

\lambda =\frac {0.6931}{T}

The equation of radioactivity used here is given by

N=N_{o}e^{-\lambda t}

N=19\times e^{-\lambda t}

(b) N = 8 gram

Substitute the values in above equation

\lambda =\frac {0.6931}{12}

λ = 0.0577 per hour

So, 8=19\times e^{-0.577t}

e^{-0.0577t}=0.421

Take natural log on both the sides

- 0.0577 t = - 0.865

t = 15 hours

An earthquake in San Francisco produces a wave with a period of 0.80 seconds and a wavelength of 40 m., How long will it take fo
gtnhenbr [62]

Answer:

A) 3.11 Hrs

Explanation:

Wave speed is given by the formula

Speed = \frac{wavelength}{Time\: period}

now we will have

speed = \frac{40}{0.80}

v = 50 m/s

now the time taken by the wave to move the distance 560 km is given as

t = \frac{distance}{speed}

t = \frac{560\times 10^3}{50}

t = 11200 s

t = 3.11 hours
