Answer:

Skateboard

Explanation:

Acceleration is change in velocity over time.

a = Δv / Δt

The airplane's acceleration is:

a = (1005 km/h − 1000 km/h) / 10 s

a = 0.5 km/h/s

The skateboard's acceleration is:

a = (5 km/h − 0 km/h) / 1 s

a = 5 km/h/s

A solid conducting sphere with radius R = 0.390 m carries a net charge of +0.650 nC.
Tom [10]

Answer:

38.5 N/C

Explanation:

The electric field generated by a charged sphere at a point outside the sphere is equivalent to the electric field generated by a single point charge, and it is given by

E=k\frac{Q}{r^2}

where

k=9\cdot 10^9 Nm^2C^{-2} is the Coulomb's constant

Q is the net charge

r is the distance from the centre of the sphere

In this problem, we have

Q=+0.650 nC=0.65\cdot 10^{-9}C

r=0.390 m

Substituting into the equation, we find

E=(9\cdot 10^9)\frac{(0.65\cdot 10^{-9}C)}{(0.390m)^2}=38.5 N/C

Intersystem crossing is:
Semenov [28]

An intersystem crossing (ISC) is a non-radiative process that involves the transition between two electronic states with different spin multiplicity. That is, when an electron is excited in a molecule in a basal singlet state (either by absorption or radiation) into a state of greater energy, an excited singlet or triplet state can be obtained.

Therefore, ISC is understood as an a non radio active transition between states with different spin multiplicity.

Correct answer is C:  a radiative transition between states with the same spin.
