A person stands 35.0 m from a flag pole. With a protractor at eye level, he finds that the angle to the top of the flag pole is

Phoenix [80]

Answer:

The flag is 16.321 meters high.

Explanation:

The situation is represented in the attached figure

In the figure we have

$tan(\theta )=\frac{H}{D}$

Given that

θ = 25.0 degrees

D = 35.0 meters

Applying values in the above equation we have

$tan(25)=\frac{H}{35.0}\\\\\therefore H=35.0\times tan(25^{o})=16.321meters$

Bacteria vary somewhat in size, but a diameter of 2.9 μm is not unusual.

Sedbober [7]

Answer:

a) 6.4 x 10^-12 cm^3

b) 17 x 10^-6 mm^2

Explanation

a). The shape is assumed to be spherical The volume = volume of a sphere = \frac{4}{3} \pi r^3

πr

V = \frac{4}{3}*3.142* 1.15^3

∗3.142∗1.15

= 6.3715 μm^3

1 μm^3 = 10^-12 cm^3

6.3715 μm^3 = 6.3715 x 10^-12 cm^3

==> 6.4 x 10^-12 cm^3

Consider the addition of an electron to the following atoms from the third period. Rank the atoms in order from the most negativ

sergeinik [125]

The question is incomplete, the atoms in the third period referred to in the question are shown in the image attached.

Answer:

Cl>Si>Ar

Explanation:

Electron affinity refers to the energy released when an atom accepts electron (s) to form a negative ion. It is a periodic property that shows similar trends as electro negativity.

Considering the atoms in period three given in the question; chlorine will have the most negative value of electron affinity. This owes to the fact that halogens accept electrons easily to form negative ions. Silicon in group 14 shows much less negative value of electron affinity while argon, a noble gas, does not accept electrons at all and has an electron affinity of zero KJMol-1 by standard.
