Apples are stored in a container (width = length = 3.5 ft) that is filled to a depth of 2.75 feet. If the unit density of an app

le is 49.3 lb/ft^3 and porosity is 31%, how many pounds of apples are in the box? Show work please.

Answer:

The mass of the apples in the box are 1145.95 lb.

Explanation:

Given that,

Width = 3.5 ft

length = 3.5 ft

Depth = 2.75 feet

Density = 49.3 lb/ft³

We need to calculate the volume

Using formula of volume

V=l\times h\times b

Put the value

V=3.5\times3.5\times2.75

V=33.6875\ ft^3

We need to calculate the mass

Using formula of density

\rho=\dfraxc{m}{V}

m=\rho\timesV

Put the value into the formula

m=49.3\times33.6875

m=1660.79\ lb

But porosity is 31 % so apples is 69% mass of total container.

So, Total mass in pounds is

M=\dfrac{69}{100}\times1660.79

M=1145.95\ lb

Hence, The mass of the apples in the box are 1145.95 lb.

Why are unit of length mass and time independent with each other?​
mariarad [96]
Масса (килограмм), длина (метр) и время (секунда) - это 3 из 7 основных единиц в системе СИ.

Базовые единицы произвольно определены как то, что они есть, поэтому они не могут быть получены.

Все другие единицы в системе СИ являются производными от 7 основных единиц, таких как скорость (метр / секунда).

Остальные 4 - это температура (Кельвин), количество вещества (моль), электрический ток (ампер) и светимость (кандела).

11111nata11111 [884]

Answer:

v_f =63 m/s

Explanation:

given,

starting force = 0 N

uniform rate increase to 36 N

time of action of Force = 35 s

mass of the body = 10 Kg

Speed of the object = ?

From the given data

if we plot F-t curve  we will get a triangular shape

we know,

Impulse = Area between F-t curve

            = (1/2) x base x height

             = 0.5 x 35 x 36

             = 630 N.s

now use Impulse-momentum theorem

Impulse = change in momentum

630 = 10 x (v_f - vi)

630 = 10 x (v_f - 0)

v_f =63 m/s

Speed of the object at 35 sec is equal to v_f =63 m/s
