Answer:
B hopefully this helps you with work
Answer:
The last significant figure is inherently uncertain because of the rounding off. The rounding-off uncertainty is usually half of the last figure's decimal-place value if no other uncertainty is expressed. As a rule of thumb results of measurements and calculations have a limited number of significant figures.
I think the correct answer from the choices listed above is the third option. The magnetic quantum number of an electron (m) designates the orientation in space of the orbital (electron cloud). <span>This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell. </span>
Answer:
speed
Explanation:
it is used because it has both magnitude and direction.
Answer:
|q1| / |q2| = 1/7
Explanation:
We are told that both particles are in the same magnetic field, B.
The charge of the first particle is q1
The charge of the second particle is q2
Let the speed of particle 1 be v1.
Let the speed of particle 2 be v2.
The magnetic force acting on particle 1 due to the magnetic field, B, is:
F1 = |q1| * v1 * B
The magnetic force acting on particle 2 due to the magnetic field, B, is:
F2 = |q2| * v2 * B
We are told that both particles experience the same magnetic force. This means that F1 = F2
Therefore:
|q1| * v1 * B = |q2| * v2 * B
=> |q1| * v1 = |q2| * v2
|q1| / |q2| = v2/v1
We are told that the speed of particle 1 is seven times that of particle 2. Hence:
v1 = 7 * v2
Hence:
|q1| / |q2| = v2 / (7 * v2)
|q1| / |q2| = 1/7
