Answer:
All electromagnetic radiation, regardless of its wavelength, travels at what is called the "speed of light". In a vacuum, it is measured as 299,792,458 meters per second. 3.0 x 108 meters per second.
Answer:
magnitude of net magnetic field at given point is
Explanation:
As we know that magnetic field due to a long current carrying wire is given as
here we we will find the magnetic field due to wire which is along x axis is given as
r = 2 m
now we have
into the plane
Now similarly magnetic field due to another wire which is perpendicular to xy plane is given as
r = 2 m
now we have
along + x direction
Since the two magnetic field is perpendicular to each other
So here net magnetic field is given as
Answer:
Mass is zero if the whole rope is horizontal. Imaginary rope.
Explanation:
With any mass at all, only a small section of the rope will be truly horizontal. The rope curve will be a a catenary.
Answer:
A. If two objects collide, each object exerts a force in the same direction as the other.
Explanation:
The magnitude of the force that the charged sphere exerts on the line of charge is 0.0181 N.
<h3>
Magnitude of force between the charges</h3>
Apply Coulomb's law of electrostatic force.
F = (kq1q2)/r²
where;
- q1 is charge 1 = 6.3 n C/m x 0.2 m = 1.26 nC
- q2 is charge 2 = -4 μC
- r is the distance between the charges = 5 cm = 0.05 m
F = (9 x 10⁹ x 1.26 x 10⁻⁹ x 4 x 10⁻⁶)/(0.05)²
F = 0.0181 N
