Answer:
When the electric field due to one is a maximum, the electric field due to the other is also a maximum, and this relation is maintained as time passes.
Explanation:
Phase of a wave or light ray is the instantaneous situation of the cycle in which the wave is at a given time.
When two waves are in phase means that the maximum and minimum of both coincide in time. They are in the same point of their cycle at the same time. And this relationship is maintained as time passes.
The waves can also be visualized as the oscillation of an electric field. (usually plotted like a sine function).
So the fact that two waves are in phase means that the maximums of their electric field coincide in time.
The relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.
<h3>What is the relation between electric intensity and flux?</h3>
The electric field is the field, which is surrounded by the electric charged. The electric field is the electric force per unit charge.
- The intensity of this electric field is the number of electric field lines which are pass perpendicular to the unit element of fixed area.
- The flux of this electric field is the number of electric field lines which are pass normally to the fixed area.
The electric flux can be given as,
When angle is zero,
Thus, the total flux is,
Thus, the relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

At each point on a 'line', the direction of the 'line' is the direction of the force
on a small test magnet placed in the field at that point.
If two 'lines' crossed at the same point, that means a small test magnet placed
at that point in the field would feel a force in two different directions.
But even if that were true, then the net effect on the small test magnet would be
the vector sum of the two forces, and they would be represented by a single net
force anyway, and therefore by a single field 'line' at that point.
Answer:
The final temperature is T2= 5.35°C
Explanation:
Apply the Gay-lussacs's law we have
P1, initial pressure= 5.00 x 10^6 Pa
T1, initiation temperature= 25.°C
P2, final pressure= 1.07 x 10^6 Pa
T2, final temperature= ?
Cross multiplying and making T2 subject of formula we have
T2= 5.35°C
Answer:
10 A
Explanation:
τ = Maximum torque of the loop = 9 mN
N = Number of turns in the loop = 50
a = side of the loop = 15 cm = 0.15 m
A = Area of the loop = a² = 0.15² = 0.0225 m²
B = magnitude of magnetic field = 0.800 T
i = magnitude of current in the loop
Maximum torque of the loop is given as
τ = N B i A
Inserting the values
9 = (50) (0.8) (0.0225) i
i = 10 A
