Answer:

The answer is C, warm ocean water evaporates and then condenses, forming a low pressure area below.

Explanation:

Ocean water evaporates caused by the heat from the sun. The evaporating water forms a cloud of warm, moist air that moves upward.

The earth has a radius of 6.38 × 106 m and turns on its axis once every 23.9 h.

Vladimir [108]

Answer:

a) V = 465.9 m/s

b) θ = 70.529°

Explanation:

Let's first calculate angular velocity of earth:

$\omega=\frac{2\pi}{23.9h}*1h/3600s$

Velocity of a person on Ecuador will be:

$V_E = \omega*R$

$V_E = 465.9 m/s$

For part b, since angular velocity is the same:

$\frac{\omega*R}{3}=\omega*(R*cos\theta )$

Solving for θ:

$\theta=acos(1/3)$

$\theta=70.529\°$

The viscosities of several liquids are being compared. All the liquids are poured down a slope with equal path lengths. The liqu

Vladimir [108]

Answer:

Move slowly and reach bottom later.

Explanation:

Viscosity is termed as the thickness or consistency of any liquid or semi liquid. It is related to the internal friction of the substance.

When several liquids are poured down with equal path lengths then the liquid will high viscosity will reach the bottom latter while one with less viscosity.

The internal friction of the molecules tends to keep them together making its consistency more thick. Thus when it will slope down from a certain height it will take more time to reach down.

If the work done to stretch an ideal spring by 4.0 cm is 6.0J, what is the spring constant (force constant) of this spring?

cluponka [151]

As AL2006 correctly pointed out the formula is 1/2 kx^2. I was thinking of force and work is the integral of force over the distance applied. So now
$W= \frac{1}{2}k x^{2}$
and
$\frac{2*6.0}{0.04^{2} } = k =7500 \frac{J}{m^{2}}$

What is amplitude? I'm pretty dumb lol

Nady [450]

According to the dictionary, amplitude is: "the maximum extent of a vibration or oscillation, measured from the position of equilibrium."
Hope this helps, and happy studying~!
