Answer:
A permanent magnet creates a magnetic field at all points in the surrounding region.
An electric current in a conductor creates a magnetic field at all points in the surrounding region.
A moving electric charge creates a magnetic field at all points in the surrounding region.
Explanation:
Magnet field is a region around the magnet in which the magnetic force can be experienced. A magnet has two poles: North pole and South pole. A Magnetic field originates from north pole and ends at south pole.
Magnets are of two types: Permanent magnet and temporary magnet.
A moving charge produces magnetic field. A stationary charge can not produce a magnetic field.
The rate of flowing charge constitutes an electric current. If the cardboard is placed around the current carrying conductor and the iron fillings spread around the cardboard then the iron nails get stick to it. It means that a current carrying conductor creates a magnetic field around it.
Therefore, the true statements from the given statements are as follows;
A permanent magnet creates a magnetic field at all points in the surrounding region.
An electric current in a conductor creates a magnetic field at all points in the surrounding region.
A moving electric charge creates a magnetic field at all points in the surrounding region.
Answer:
Net Force = 0
Explanation:
Causes objects to accelerate. Balanced Forces. Two equal forces push in opposite direction causing no change in motion causing net force = 0.
Answer:
I think is Number 2
The rate at which calcium chloride is equal to the rate at which sodium chloride is produced.
Let me know if I'm wrong.
Answer:
<em>The current is 11 Amperes</em>
Explanation:
<u>Electric Current</u>
The electric current is defined as a stream of charged particles that move through a conductive path.
The current intensity can be calculated as:
Where:
Q = Electric charge
t = Time taken by the charge to move through the conductor
The current intensity is often measured in Amperes.
The charge passing through a point in a circuit is Q= 55 c during t=5 seconds, thus the current intensity is:
I = 11 Amp
The current is 11 Amperes
The frequency of the light beam is 4.72 x 10¹⁴ Hz.
<h3>
Frequency of the light beam</h3>
The frequency of light beam and wavelength of light is related in the following equations;
c = fλ
where;
- c is the speed of light = 3 x 10⁸ m/s
- f is the frequency
- λ is the wavelength
f = c/λ
f = (3 x 10⁸) / (636 x 10⁻⁹)
f = 4.72 x 10¹⁴ Hz
Thus, the frequency of the light beam is 4.72 x 10¹⁴ Hz.
