Answer:
Explanation:
The wires are in circular shape . They have common center .
magnetic field due to circular wire is given by the formula
B =
where I is current , r is radius of the coil .
magnetic field due to inner wire
=
magnetic field due to outer wire
=
These should be equal and opposite so that by cancelling each other , they create zero field.
=
I = 16.66 A
Direction of current should be in opposite direction ie anticlockwise when looking from above.
Answer:
Graph C
Explanation:
This is the answer because it is the only one that shows the vehicle accelerate to a constant speed before stopping and slowing down.
Answer:
1. is the age group 35 and 44
2. is 2006 i think its 2006 i cant really tell in the picture but its the one before the last one!
Hello,
To start off, Your answer is Refraction.Refraction is always accompanied by a wavelength. So that is why the wave moves from one medium to another.
Hope this helps
Answer:
Force
Explanation:
The mass of an object is the quantity of matter it contains. It is measured in kilograms.
Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/.
When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.
i.e F = m × a
where F is the force, m is the mass of the object and a its acceleration.
The two major classes of force are; contact force and field force.
