Answer:

Ozone, or trioxygen, is an inorganic molecule with the chemical formula O ₃. It is a pale blue gas with a distinctively pungent smell. It is an allotrope of oxygen that is much less stable than the diatomic allotrope O ₂, breaking down in the lower atmosphere to O ₂.

Use the collision theory to explain how increasing the temperature of a reaction will affect the rate of the reaction.

kirill115 [55]

Increasing the temperature causes the particles in the reaction to become kinetically excited, hitting one another in increasing frequency. Increased collision among means faster rate or reaction.

Describe a change caused by kinetic energy as well as a change that involves potential energy

kykrilka [37]

Kinetic energy is formed when the object is in motion.
Potential energy is the energy that is formed relative to others.

One of the example is Corn flour factory.

Corn turned into flour by a windmill that moved by the waterfall. Movement of the mill is relative to the power given by waterfall (potential energy) and the spinning crushes the corn into flour (kinetic energy)

f your risk-aversion coefficient is A = 4 and you believe that the entire 1926–2015 period is representative of future expected

siniylev [52]

Answer:

The portfolio should invest 48.94% in equity while 51.05% in the T-bills.

Explanation:

As the complete question is not given here ,the table of data is missing which is as attached herewith.

From the maximized equation of the utility function it is evident that

$Weight=\frac{E_M-r_f}{A\sigma_M^2}$

For the equity, here as

$Weight$ is percentage of the equity which is to be calculated
${E_M-r_f}$ is the Risk premium whose value as seen from the attached data for the period 1926-2015 is 8.30%
$A$ is the risk aversion factor which is given as 4.
$\sigma_M$ is the standard deviation of the portfolio which from the data for the period 1926-2015 is 20.59

By substituting values.

$Weight=\frac{E_M-r_f}{A\sigma_M^2}\\Weight=\frac{8.30\%}{4(20.59\%)^2}\\Weight=0.4894 =48.94\%$

So the weight of equity is 48.94%.

Now the weight of T bills is given as

$Weight_{T-Bills}=1-Weight_{equity}\\Weight_{T-Bills}=1-0.4894\\Weight_{T-Bills}=0.5105=51.05\%\\$

So the weight of T-bills is 51.05%.

The portfolio should invest 48.94% in equity while 51.05% in the T-bills.

The __________ states that the firing rate of neurons in the auditory nerve matches the frequency of the sound wave.

borishaifa [10]

Correct answer choice is:

C. Volley principle (FREQUENCY MATCHING)

Explanation:

Volley theory declares that groups of neurons of the hearing rule counter to a noise by firing action potentials imperceptibly out of the stage with one another so that when connected, a higher pulse of sound can be encoded and transmitted to the brain to be examined.

What are the strength and direction of an electric field that will balance the weight of a 0.9 g plastic sphere that has been ch

Vladimir79 [104]

(a) The force exerted by the electric field on the plastic sphere is equal to
$F=qE$
where $q=-3.4 nC=-3.4 \cdot 10^{-9} C$ is the charge of the sphere and E is the strength of the electric field. This force should balance the weight of the sphere:
$F=mg =0.9 g$
where m is the mass of the sphere and g is the gravitational acceleration.

Since the two forces must be equal, we have:
$qE=mg$
and so we find the intensity of the electric field
$E= \frac{mg}{q}= \frac{0.9 \cdot 9.81 m/s^2}{3.4 \cdot 10^{-9} C} =2.6 \cdot 10^9 N/C$

(b) Now let's find the direction of the field. The electric force must balance the weight of the sphere, which is directed downward, so the electric force should be directed upward. Since the charge is negative, the force is opposite to the electric field direction, and so the direction of the electric field is downward.
