The sympathetic nervous system ____________digestion and _____________blood pressure. (2 points)

Physics
1 answer:
Talja [164]4 years ago
3 0

Answer:

The sympathetic nervous system _____decelerates_______digestion and __accelerates___________blood pressure. See the explanation below, please.

Explanation:

The sympathetic nervous system together with the parasympathetic make up the autonomic nervous system. The sympathetic system acts in situations of stress, prepares the body for "fight or flight", increases heart rate and blood pressure at the cardiovascular level, at the digestive level it slows down the system, produces bronchodilation, pupil dilation (mydriasis).

SashulF [63]

Answer: 2045

Explanation:

Given

We had sent a radio signal to advance civilization in 2006 which is 39 light-years away i.e. time taken by light to reach reticuli star system is 39 years.

So, it will arrive the destination in the year 2006+39=2045

The resolving power of a microscope is proportional to the wavelength used. A resolution of 1.0 10-11 m (0.010 nm) would be requ
Anon25 [30]

Answer:

K = 13448.64eV

Explanation:

(a) In order to calculate the kinetic energy of the electrons, to "see" the atom, you take into account that the wavelength of the electrons must be of the order of the resolution required (0.010nm).

Then, you first calculate, by using the Broglies' relation, the momentum of the electron associated to a wavelength of 0.010nm:

p=\frac{h}{\lambda}       (1)

p: momentum of the electron

h: Planck's constant = 6.626*10^-34 Js

λ: wavelength = 0.010nm

You replace the values of the parameters in the equation (1):

p=\frac{6.262*10^{-34}Js}{0.010*10^{-9}m}=6.262*10^{-23}kg\frac{m}{s}

With this values of the momentum of the electron you can calculate the kinetic energy of the electron by using the following formula:

K=\frac{p^2}{2m}    (2)

m: mass of the electron = 9.1*10^-31 kg

K=\frac{(6.262*10^{-23}kgm/s)^2}{2(9.1*10^{-31}kg)}=2.15*10^{-15 }J

In electron volts you obtain:

2.15*10^{-15}J*\frac{6.242*10^{18}eV}{1J}=13448.64eV

The kinetic energy required for the electrons must be, at least, of 13448.64 eV

katrin2010 [14]

Answer:

b.) the diverge in incident beam of light

Explanation:

A lens refers to any refracting surface. The manner in which a lens is curved tells whether it is a concave(diverging) lens or a convex (converging) lens.

A convex lens is thicker at the center than at the edges. It makes light to converge at a point.

A concave lens is is thinner at the center than at the edges. It makes light to appear to diverge from a point, hence the answer above.
