Answer:

ENERGY STAR-certified dishwashers

Explanation:

use advanced technology to get dishes clean while using less water and energy. Soil sensors test the degree of dirt on dishes throughout the wash and adjust the cycle to achieve optimum cleaning with minimal water and energy use.

Energy-Saving “No-Heat” Dry

Most new dishwashers offer an energy-saving no-heat drying feature. At the end of the rinse cycle, if the feature is selected, room air is circulated through the dishwasher by fans, rather than using an electric heating element to bake the dishes dry.

Distribution intensity is commonly divided into three levels:

gregori [183]

It is indeed divided into Intensive, exclusive, and selective disribution. let me explain them. When we talk about Intesive distribution we say that we have a strategy that is designed to place products in as many outlets as possible. The exclusive distribution is when we recognize policy by granting exclusive geographic territories to one or very few retail customers so no other retailers in the territory can sell a particular brand. And when we talk about selective distribution we know that it lies in between the intensive and exclusive distribution strategies because it uses a few selected customers in a territory

A ball of mass 0.190 kg has a velocity of 1.50 i m/s; a ball of mass 0.305 kg has a velocity of -0.401 i m/s.They meet in a head

Mice21 [21]

Answer:

Explanation:

According to law of conservation of momentum, the momentum of the object before collision is equal to that of the object after collision. Using the formula

m1u1 + m2u2 = (m1+m2)v

m1 and m2 are the masses of the object

u1 and u2 are the respective initial velocities

v is the final velocity

Given

m1 = 0.190kg

u1 = 1.5m/s

m2 = 0.305kg

u2 = -0.401m/s

Substitute

0.19(1.5)+(0.305)(-0.401) = (0.19+0.305)v

0.285 - 0.122305 = 0.495v

0.162695 = 0.495v

v = 0.162695 /0.495

v = 0.329m/s

Hence their velocities after collision is 0.329m/s in the positive x direction
