Answer:
The wavelength of a wave is 1.72 m.
Explanation:
Given,
Frequency, f = 0.9 Hz
Speed of a wave, v = 154.9 cm/s = 1.549 m/s
The speed of a wave is given by :
![v=f\lambda](https://tex.z-dn.net/?f=v%3Df%5Clambda)
![\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{1.549\ m/s}{0.9\ Hz}\\\\\lambda=1.72\ m](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bv%7D%7Bf%7D%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7B1.549%5C%20m%2Fs%7D%7B0.9%5C%20Hz%7D%5C%5C%5C%5C%5Clambda%3D1.72%5C%20m)
So, the wavelength of a wave is 1.72 m. Hence, this is the required solution.
Explanation:
Walmart is a supermarket giant working across the oceans in the market, creating a huge fortune from it.
Some terms that Walmart followed to build its empire are as follows.
Efficient Supply Chain
The supply chain of Walmart is one of the most effective supply chain in the world, the supermarket giant uses very less break-in between the supplier and their store to minimize costs and increase overall profit.
Strategic partnership
Strategic alliance is one of the main reasons for the popularity of Walmart Walmart finds the best product provider and tells them if they can meet the demand then there is a long-term relationship plan that lowers costs.
Intuitive inventory storage
Walmart uses very intuitive way of storing the inventory, It keep its inventory in truck and then later the inventory is loaded to the semi truck without moving them to the warehouse , this broadly increases the efficiency of the transportation and time.
Using latest technology
Walmart uses state of the art sorting and transporting technologies to ensure the required quality and speed it requires and to obtain high profits and and super efficient system.
Walmart used the above mentioned words to create an environment for low-cost manufacturing. This concentrated on the biggest group of people in the middle class and the aim was to provide great quality low cost merchandise. Walmart provided the best procurement and distribution system to reduce prices and therefore consumers got the goods at the best price and higher quality.
Walmart has changed its all slogan from "always low prices" to "save money. live better". Does a specific changes the competitiveness of the market and reflect the competitions effect in the new slogan.
The kinetic energy of a 750 kg car moving at 50.0 km h is 72300 joules.
Given,
mass of car (m)= 750 kg
speed of car (v)= 50 km/h
= 50 x 5/18
= 13.9 m/s
we know that kinetic energy= 1/2 x m x v*v
= 1/2 x 750 x 13.9 *13.9
= 72300 joules
so the kinetic energy is 72300 joules.
Energy is the capacity of an object to do work, and like work, energy's unit is the joule (J). Energy exists in many different forms, but the one we think of most often when we think of energy is kinetic energy. Kinetic energy is often thought of as the energy of motion because it is used to describe objects that are moving.
