The s s -subshell has only one orbital while the p p -subshell has three orbitals. Thus, a total of four orbitals are present which can contain a maximum of 4×2 4 × 2 = 8 8 electrons. So eight electrons can have this quantum number.

Answer:
the change in energy of the block due to friction is
Explanation:
From the question we are told that
The frictional force is
The mass of the block is
The length of the ramp is
The height of the block is
The change in energy of the block due to friction is mathematically represented as
The negative sign is to show that the frictional force is acting against the direction of the block movement
Now substituting values
The dipole moment of a molecule and its boiling point are directly varied. If the dipole moment is large, the attraction between the positive and negative charges of a molecule is strong thus, requiring stronger forces to break them. Hence, they will have higher boiling points.
Answer:
Explanation:
The weight of the bee is:
with m the mass and g the gravity acceleration.
Electric force of the bee is related with the electric field of earth by:
with q the charge, E the electric field and Fe the electric force.
So:
Because Newton's first law we should make the net force on it equals cero:
with W the weight, Fe the electric force on the bee due earth's electric field and F the force.
So, the applied electric field should be:
The negative sign indicates that the electric field should be opposite to earth's electric field, so it should be upward.
