No.
The flow of electrons is in the opposite side to the flow of convectional current.
Convectional current is considered to be the flow of positive charges from the positive terminal of the cell called anode to the negative terminal of the cell called cathode through the external circuit.
Electrons flow from cathode to the anode of the cell through the external circuit.
Answer:
Explanation:
Given
-- Mass of the boy
-- Mass of the girl
-- Acceleration of the girl towards the boy
Required
Determine the acceleration of the boy towards the girl ()
From the question, we understand that the surface is frictionless. This implies that the system is internal and the relationship between the given and required parameters is:
Substitute values for and
Make the subject
<em>Hence, the acceleration of the boy towards the girl is 1.446m/s^2</em>
The answer is 3, 240J
KE=1/2 m v^2
KE= 1/2(45kg)(12m/s)^2
KE=1/2*45*144
KE= 3, 240 Joules
Similarities: They are waves, they both displace particles, both transfer energy
Differences: Transverse- particles move perpendicularly, waves are perpendicular to direction, and they are 2 dimension . Longitudinal- particles are displaced same direction as a wave, move left and right, and are one dimension
How to measure:
Transverse- measure 2 adjacent crests or troughs
Longitudinal- measure from one rare faction to another or one compression to another
Example: Transverse- vibrations in string . Longitudinal- sound waves
