Answer:
A or B you choose
Explanation:
This is called current electricity or an electric current. A lightning bolt is one example of an electric current, although it does not last very long. Electric currents are also involved in powering all the electrical appliances that you use, from washing machines to flashlights and from telephones to MP3 players.
what is an electrical current, amp, ampere Current is the flow of electrons. When a circuit is closed then a current of electrons can flow and when a circuit is open then no current can flow. We can measure the flow of electrons just like you can measure the flow of water through a pipe.
Answer:
d.solid to liquid cause they were once on a fixed and started to slide.liquid particles slide along a container so it is a solid to liquid
Distorted maps attempt a compromise, cutting the terrestrial surface along some arbitrarily chosen lines, then projecting each lobe (or gore, in case of interruptions, repeat periodically along related lines like meridians), separately with lower overall deformation. Gore boundaries are often designed to fall on less important areas, like oceans.
Answer:
F = 10.86 units
Explanation:
The magnitude of a vector in terms of the magnitude of its rectangular components is given by the following formula:
F = √(Fₓ² + Fy²)
where,
F = Magnitude of the Vector = ?
Fₓ = magnitude of the x-component of vector = 8.7 units
Fy = magnitude of y component of vector = - 6.5 units
Therefore, using these values in the equation, we get:
F = √[(8.7 units)² + (- 6.5 units)²]
F = √(117.94 units²)
<u>F = 10.86 units</u>
Answer:
The direction of propagation is west.
Explanation:
We know that electromagnetic waves (EM-waves) are transverse in nature. EM-waves containing electric field and magnetic field both are perpendicular to the each other ( E ⊥ B ).
Transverse waves : the direction of propagation is perpendicular to the direction of amplitude which we call transverse waves. eg : light waves, water waves, gravitational waves etc.
Here, in our case the direction of electric field is pointing upward to the plan of the screen and the direction of magnetic field is pointing north
∴ 
× 
Where 
direction of electric field, 
direction of magnetic field, 
direction of propagation at particular instant.
Above equation follows right hand rule. put your finger toward you (out of the screen) then curl to the north side then the thumb will give you the direction of the wave propagation ( west side )
In our case west direction is the direction of wave propagation.
