Work output of a large machine in a factory is 89,000 joules, and it’s input is 102,000 joules. Work output of a similar machine
mojhsa [17]
(89000/102000)×100
=87.25%

(92000/104000)×100
=88.46%

efficiency is (output/input)×100
if u get confused which way input and output should go, remember the smaller value is always output and it's above in the fraction, then only it's possible to get a efficiency lower than 100.

A 2kg blob of putty moving at 4 m/s slams into a 6kg blob of putty at rest what is the speed of the to stick together blobs imme
andrew11 [14]
<h2>Answer</h2>

1m/s

<h2>Explanation</h2>

Given that:

<em>Mass of first blob = 2kg = m1</em>

<em>Velocity of blob = 4m/s = v1</em>

<em>Mass of second blob = 6kg = m2</em>

<em>Velocity of blob = 0m/s = v2</em>

<em />

To find:

<em>Final velocity = Vf</em>

<em />

<em>This question is of inelastic collision which is any collision between objects in which some energy is lost.</em>

<em />

<h3>Formula to be use:</h3><h2>(m1*v1) + (m2*V2) = Vf(m1 + m2)</h2>

(2*4) + (6*0) = Vf(2+6)

8 + 0 = Vf(8)

8 = Vf(8)

Vf = 1 m/s

So the speed of two blobs immediately after colliding = 1 m/s

The center of gravity method is used to ________ travel time
icang [17]

Answer:

minimizes

Explanation:

The center of gravity method consists of an algorithm for the location of an installation considering existing ones. This is a very simple technique and is usually used to determine the location of intermediate warehouses and distribution points taking into account the distances that separate them and the contribution (in terms of utility, production or capacity) of each installation.

This location method takes into account three transport factors:

Ci: Transportation cost per unit

Vi: Volume transported from unit i

di: Distance traveled in the transport of the unit i

The primary objective of this method is to find the best location of a given installation of a company with respect to the other elements that make it up, to guarantee the minimum possible time and the minimum Total Transportation Cost.
