In a posteroanterior (pa) projection of the chest being used for cardiac evaluation, the heart measures 14.7 cm between its widest points. if the magnification factor is known to be 1.2, what is the actual diameter of the heart?

Answers

Answer 1

Answer:

The actual diameter of the heart is 12.25 cm. Given : Heart measure = 14.7 cm Magnification factor = 1.2

14.7 / 1.2 = 12.25

A wire that is 0.36 meters long moves perpendicularly through a magnetic field at a speed of 0.21 meters/second. The induced emf produced in the wire is 0.45 volts. What is the magnetic field strength?

Answers

Answer:

Magnetic field strength, B = 5.95 Tesla

Explanation:

It is given that,

Length of wire, l = 0.36 m

It is moving perpendicularly through a magnetic field at a speed of, v = 0.21 m/s

Induced emf, E = 0.45 volts

The mathematical expression for induced emf is given by :

$E=(d\phi)/(dt)=Blv$

$(d\phi)/(dt)$ is the rate of change of magnetic flux,

B is magnetic field

So, $B=(E)/(lv)$

$B=(0.45)/(0.36* 0.21)$

B = 5.95 Tesla

Hence, this is the required solution.

Which of the following groups of environmental science careers are most similar?a. Hydrologist, toxicologist, environmental lawyer
b. Environmental physician, environmental veterinarian
c. Environmental activist, oceanographer, ecologist
d. Oceanographer, Environmental journalist

Answers

The correct answer for the question that is being presented above is this one: "b. Environmental physician, environmental veterinarian." The groups of environmental science careers that are most similar is that of Environmental physician and environmental veterinarian.

Correct answer choice is:

B. Environmental physician, environmental veterinarian.

Explanation:

Environmental medicine is a field involving several academic disciplines including physicians, environmental science, chemistry and many other related fields, protruding with environmental diagnostics. The extent of this domain includes examining the interplay's between ecosystem and human health, and the role of the atmosphere in producing or negotiating infection. Likewise, In the wildlife division, doctors are frequently defied with the outcomes of environmental contaminants and contagious infection disorders that probably endanger wild and housebroken animals as well as individuals.

Water surface waves are _________.. a. longitudinal and perpendicular waves. b. vertical and horizontal waves. c. transverse and horizontal waves. d. longitudinal and transverse waves

Answers

Water surface waves are examples of waves that are both longitudinal and transverse waves. As the wave travels through the water, a clockwise circles is observed. Therefore, the answer to this item is letter D. All the rest of the choices do not describe the water surface waves.

A football is kicked into the air with a velocity of 32m/s at an angle of 25º. At the very top of the ball’s path, its vertical velocity is

Answers

At the "very top" of the ball's path, there's a tiny instant when the ball
is changing from "going up" to "going down". At that exact tiny instant,
its vertical speed is zero.

You can't go from "rising" to "falling" without passing through "zero vertical
speed", at least for an instant. It makes sense, and it feels right, but that's
not good enough in real Math. There's a big, serious, important formal law
in Calculus that says it. I think Newton may have been the one to prove it,
and it's named for him.

By the way ... it doesn't matter what the football's launch angle was,
or how hard it was kicked, or what its speed was off the punter's toe,
or how high it went, or what color it is, or who it belongs to, or even
whether it's full to the correct regulation air pressure. Its vertical speed
is still zero at the very top of its path, as it's turning around and starting
to fall.
