Answer and explanation;

-The cause of convention currents in a hot spring is rainwater and melted snow is cool and denser and sinks to the bottom of the hot spring where it is heated by a shallow magma chamber. The heated water expands and is less dense and rises to the top.

Explanation;

-Convention Current is the movement of fluid caused by the differences in temperature. Transference of heat from one part of a fluid to another.

-Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.

A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provid

Sergeeva-Olga [200]

Answer:

$8.37*10^5$ rpm

Explanation:

Given that rotational kinetic energy = $4.66*10^9J$

Mass of the fly wheel (m) = 19.7 kg

Radius of the fly wheel (r) = 0.351 m

Moment of inertia (I) = $\frac{1}{2} mr ^2$

Rotational K.E is illustrated as $(K.E)_{rt} = \frac{1}{2} I \omega^2$

$\omega = \sqrt{\frac{2(K.E)_{rt}}{I} }$

$\omega = \sqrt{\frac{2(KE)_{rt}}{1/2 mr^2} }$

$\omega = \sqrt{\frac{4(K.E)_{rt}}{mr^2} }$

$\omega = \sqrt{\frac{4*4.66*10^9J}{19.7kg*(0.351)^2} }$

$\omega = 87636.04$

$\omega = 8.76*10^4 rad/s$

Since 1 rpm = $\frac{2 \pi}{60} rad/s$

$\omega = 8.76*10^4(\frac{60}{2 \pi})$

$\omega = 836518.38$

$\omega = 8.37 *10^5 rpm$

what are some challenges of scuba diving and how do pressure variations in depth affect our ability to explore the ocean?

sergiy2304 [10]

Pressure variations affect our ability to explore by limiting how deep we can go. this reason is because as we go deeper in the ocean the pressure increases and can crush you if you go deep enough.

A youngs interference experiment is performed with blu-green argon laser light .The slits is 0.5mm, and the screen is located 3,

hammer [34]

Answer:

515 nm

Explanation:

The equation that gives the position of the maxima (bright fringes) in the interference pattern produced on a distant screen by the diffraction of light through two slits is

$y=\frac{m\lambda D}{d}$

where

y is the distance of the maximum (bright fringe) from the central maximum

m is the order of the maximum

$\lambda$ is the wavelength of the light used

D is the distance of the screen

d is the separation between the slits

In this problem we have:

$d=0.5 mm = 0.5\cdot 10^{-3} m$ is the separation between the slits

D = 3.30 m is the distance of the screen

m = 1 (we are analyzing the 1st bright fringe)

$y=3.40 mm = 3.40\cdot 10^{-3} m$ is the distance of the 1st bright fringe from the central maximum

Solving for $\lambda$ , we find the wavelength of the light used:

$\lambda=\frac{yd}{mD}=\frac{(3.40\cdot 10^{-3})(0.5\cdot 10^{-3})}{(1)(3.30)}=5.15\cdot 10^{-7} m = 515 nm$

Vikentia [17]

The type of logical fallacy that Jonah has used is Hasty generalization. That is option D.

<h3>What is logical fallacy?</h3>

Logical fallacy is defined as those arguments that are based on false logics which may sound convincing but they are false.

Hasty generalisation is defined as the type of fallacy that is being made based on an insufficient evidence about another individual.

From the excerpt given, Jonah is a job seeker for the position of an editor of a school together with other applicants. He said that the other student who wants the position is a horrible writer.

There is no evidence to prove that the student is a bad writer therefore it's a Hasty generalization fallacy.
