Newton's second law states the following:

The change of movement is directly proportional to the force applied to the body and occurs in the direction where the force is applied.

In other words, we have:

F = ma

Where,

F: net force acting on the body

m: body mass (proportionality constant)

a: body acceleration

Answer:

Newton’s Law that involves mass and acceleration is:

2nd Law

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

Agata [3.3K]

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.

How long would it take you to travel 163 meters at a speed of 33 meters per second?

Leviafan [203]

Speed=

$33m {s}^{ -1}$

Distance=

$163m$

speed= distance/time

So,

Time= distance/speed

Time= 163/33

A parallel plate air capacitor of value C, is charged to a potential V, between

k0ka [10]

Answer:

(i) C=3Co

(ii) V=Vo/3

(iii) Decrease

Explanation:

(i) capacitance increase K times.

(ii) As charge remain constant so by using Q=CV

you will get potential decrease by K time.
