How much does it cost to run a computer for 50 hours in a week if the monitor runs on 140 Watts and the tower runs on 160 Watts and the Electric Company charges 11.2 cents per kilowatt-hour?

140W + 150W = 300W = 0.3kW
0.3kW x 50 hours = 15kW-hrs
15kW-hrs x 11.2 cents = 168 cents.

First, calculate the total power consumption per hour: 140W (monitor) + 160W (tower) = 300W. Then convert to kilowatts: 300W / 1000 = 0.3kW. Next, find the total energy consumed per week: 0.3kW * 50 hours = 15kWh. Finally, calculate the cost: 15kWh * $0.112/kWh = $1.68 for running the computer for 50 hours in a week.

What is the movement of electric charges in a closed circuit?
Electric Current
What is the basis of statement that lines of electric force begin end only in charges?
The basis for this statement is the concept of electric field lines originating from positive charges and terminating on negative charges. This is in accordance with the fundamental property of charges where opposite charges attract each other. Therefore, electric field lines cannot start or end in empty space, as they always originate from and terminate on charges.
What does the law of electric charges say about two objects that are positive charged?
The law of electric charges states that like charges repel each other. Therefore, if two objects are both positively charged, they will repel each other due to the like charge.
What particles have negative electric charges equal to the positive charges of the protons?
Electrons have negative electric charges equal in magnitude to the positive charges of protons.
What are the 2 types of electric charges?
The two types of electric charges are positive and negative. Positive charges repel each other, as do negative charges, while positive and negative charges attract each other.
The flow of electric charges is called?
The flow of electric charges is current.
What does the flow of electric charges create?
The flow of electric charges creates an electric current, which is the movement of electric charges through a conductor. This current can be harnessed to power electrical devices and systems.
What is a pair of electric charges called?
flow of electricity through a conductor are electric charges
How do like electric charges react other?
Like electric charges - charges of the same sign - repel each other.
How much does it cost to run a computer for 50 hours in a week if the monitor runs on 140 Watts and the tower runs on 260 Watts and the Electric Company charges 11.2 cents per kilowatt-hour?
It would cost $2.24 in electricity to run the computer 50 hours in a week.
What are the characteristics of stationary electric charges?
Stationary electric charges do not move and remain in a fixed position. They create an electric field around them that can interact with other charges or objects nearby. These charges can attract or repel other charges depending on their polarity.
What are the two causes of electric and magnetic forces?
Electric forces are caused by the attraction or repulsion of electric charges, while magnetic forces are caused by the motion of electric charges.
What are stationary electric charges called?
Stationary electric charges are called static charges. These charges do not move and are typically found on objects that have gained or lost electrons.
What is the device that detects electric charges?
An electrometer is a device that detects electric charges by measuring the voltage or current associated with the charges.
What does a positive electric chrge do?
A positive electric charge creates an electric field around it and interacts with other charges. It repels other positive charges and attracts negative charges. Positive charges move towards areas of lower voltage in an electric field.
What surrounds electric charge and exerts force on other charges?
Electric charges are surrounded by an electric field, which exerts a force on other charges. This force can either attract or repel depending on the charges involved and their distance from each other.
What do you call it when charges are moving?
When charges are in motion, it is called electric current. Electric current is the flow of electric charge through a conductor.
