Answer:
In a nutshell, units of A and B are and , respectively.
Explanation:
From Dimensional Analysis we understand that and have length units () and have time units (). Then, we get that:
(Eq. 1)
(Eq. 2)
Now we finally clear each constant:
In a nutshell, units of A and B are and , respectively.
Answer:
The current in the wire = 39.53 A.
Explanation:
The given cross -sectional area of the wire = 1.35 .
The number of electrons flowing in the wire at any point is
= 5.41 electrons.
The charge of an electron is known to be =
The electronics flow across the wire for a time of, t = 2.19 seconds.
The current in the wire = (number of electrons) ×
= 5.41 ×
= 39.53 A.
The formula for current is actually, i = .
The (number of electrons )×(charge of an electron) will equal the total charge flowing through the wire in the given time = 2.19 seconds.
The current in the wire = 39.53 A.
Because they're quadcopters
Answer:
Ondas y sonido. Una onda es una perturbación que avanza o que se propaga en un medio material o incluso en el vacío. ... El sonido es un tipo de onda mecánica que se propaga únicamente en presencia de un medio material.

Answer:
Free body diagram
Explanation:
A free body diagram shows all the forces acting on an object. an example would be a box sitting on the floor.
Draw a square and you would have an arrow from the box pointed down to represent gravity pulling the box down and an arrow from the box pointing upwards to represent the normal force of the ground pushing back. in the scenario the two arrows would be equal length because the forces balance out since the box is motionless. in a situation where there is motion one arrow would be bigger such as if a box was falling. in this example it would have an arrow down to show gravity but no arrow up because it is in free fall. The sum of the forces which is represented by the arrows is what your net force is. The free body diagram helps you visualize all the forces acting on an object.
