The answer should be B. a stable isotope to a decaying isotope.
Answer:
The magnetic flux through a loop is zero when the B field is perpendicular to the plane of the loop.
Explanation:
Magnetic flux are also known as the magnetic line of force surrounding a bar magnetic in a magnetic field.
It is expressed mathematically as
Φ = B A cos(θ) where
Φ is the magnetic flux
B is the magnetic field strength
A is the area
θ is the angle that the magnetic field make with the plane of the loop
If B is acting perpendicular to the plane of the loop, this means that θ = 90°
Magnetic flux Φ = BA cos90°
Since cos90° = 0
Φ = BA ×0
Φ = 0
This shows that the magnetic flux is zero when the magnetic field strength B is perpendicular to the plane of the loop.
Answer:
Z
Explanation:
The purple and yellow rays from the same point on the object are shown converging at point Z, where the image will be.
Answer:
0.046
Explanation:
displacement = velocity/ time
d = 6m/s / 130s
d = 0.046m
It can’t be b because that will increase the dissolving rate
