What are the advantages of using an electric motor over other types of motors?
The advantages of using an electric motor over other types of motors include higher efficiency, lower maintenance requirements, quieter operation, and better control over speed and torque.
What type of magnetic field will produce an electric current in a wire?
A current carrying wire has a magnetic field around it but no electric field.There will be electric field around a body only if it has static electricity.In this wire, charges(electrons) are moving.The number of charges entering is equal to number of charges leaving the conductor.So it remains neutral.A neutral body cannot have an electric field around it. ACTUALLY, there IS also an electric field. A current is made up of moving charges, and all charges (moving or static) create an electric field. Materials that have a neutral charge are not good conductors and therefore would not have a current going through them in the first place.
How could you calculate the speed at which a thunderstorm cell is moving?
To calculate the speed at which a thunderstorm cell is moving, you can track its position over time using radar data or satellite imagery. Measure the distance the storm travels between two points over a specific time interval. The speed can then be calculated using the formula: speed = distance/time. This will give you the storm's movement in miles per hour or kilometers per hour.
What happens to the speed of an object as it travels farther without any additional force added to it?
Newton's First Law explains what happens in this case.If no force acts on the object, its speed won't change over time. In fact, its velocity won't change either.
What is the symbol for the speed of light?
Normally its a lowercase c, as in E=m(c)2. Energy=mass times the speed of light squared.
What is the equation to find the speed the car travels over a distance?
Speed = Distance / Time
WHAT IS A MEASURE OF HOW A WAVE TRAVELS OVER TIME?
Speed of the wave.
What are parts of an electromagnetic wave?
Electric field and magnetic field
What is the speed of which a wave travels through a medium?
Over 6,000 mph.
Which of these is the measure of distance a wave travels over time?
wave speed
How long does the electric field extend?
The electric field extends over a distance infinitely, theoretically. However, the strength of the field decreases with distance from the source charge.
What is a field in the electromagnetic spectrum?
There are electric fields and magnetic fields. If those change over time, the changes may propagate at the speed of light - that's called an electromagnetic wave.
What do you mean by electric flux?
Electric flux measures the flow of electric field through a surface. It is defined as the dot product of the electric field and the normal to the surface, integrated over the surface area. It represents the number of electric field lines passing through a given area.
What is meant by total normal electric induction over a surface?
Total normal electric induction over a surface refers to the total electric flux passing through the surface when the electric field is perpendicular to the surface. It is a measure of the total electric field passing through the surface and is calculated by the dot product of the electric field and the surface area vector.
What is the average speed of a car that travels 120 kilometers in two hours?
speed = distance over time speed = 120/2 = 60 km/hr
The distance an object travels per unit of time is called?
Speed. The equation to find speed is distance over time.
What happens to an objects speed if it travels with constant acceleration?
If an object travels with constant acceleration, its speed will change at a constant rate over time. The object's speed will increase if the acceleration is positive, decrease if it is negative, and remain constant if the acceleration is zero.
