A vector is any quantity that has both a size and a direction.

Some examples of vector quantities: velocity, acceleration, displacement, electrostatic field, magnetic field, momentum, force

They all have different units of measurement for their sizes.

____ [38]

Answer:

Hello, Your answer should be is Auditory Nerve

Explanation:

Because the "Auditory Nerve" bundle of nerves that carries hearing information, The cochlear nerve, also known as the acoustic nerve, is the sensory nerve that transfers auditory information from the cochlea (auditory area of the inner ear). Its not A, because the "Optic nerve" second pairs of cranial transmitting impulses to the brain. Its not really C, Because the "Cochlea" is a spiral cavity that is inside of the inner ear. And its not D, because the "Stirrup" is the stapes or stirrup is on the bone, by the middle ear of humans and mammels too. So your best answer will be Auditory Nerve.

Particles q1 = -53.0 uc, q2 = +105 uc, and

Nimfa-mama [501]

Answer:

$-180.38\ \text{N}$

Explanation:

$q_1=-53\ \mu\text{C}$

$q_2=105\ \mu\text{C}$

$q_3=-88\ \mu\text{C}$

r = Distance between the charges

$r_{12}=0.5\ \text{m}$

$r_{23}=0.95\ \text{m}$

$r_{13}=1.45\ \text{m}$

k = Coulomb constant = $9\times 10^9\ \text{Nm}^2/\text{C}^2$

Net force is given by

$F=F_{12}+F_{13}\\\Rightarrow F=\dfrac{kq_1q_2}{r_{12}^2}+\dfrac{kq_1q_3}{r_{13}^2}\\\Rightarrow F=kq_1(\dfrac{q_2}{r_{12}^2}+\dfrac{q_3}{r_{13}^2})\\\Rightarrow F=9\times 10^9\times (-53\times 10^{-6})(\dfrac{105\times 10^{-6}}{0.5^2}+\dfrac{-88\times 10^{-6}}{1.45^2})\\\Rightarrow F=-180.38\ \text{N}$
