Answer:

Deep ocean trenches

Explanation:

Subduction zones are Earth's lithosphere (the crust and as well as the upper non-convecting part of the upper mantle) gravitational collapsing sites. Along convergent plate boundaries, subduction zones exist where one sheet of oceanic lithosphere merges with any other layer. So, in order to find  depth of water in the sea, we can find these subduction zones. The best places are a deep ocean- trench like the Mariana Trench in the pacific ocean.

Which statements describe elliptical galaxies? *Select the two correct answers.*
Alecsey [184]

Elliptical galaxies are galaxies that are shaped like an ellipse. An ellipse is oval in shape, which means elliptical galaxies are oval in shape.

The <u>two correct statements</u> that describe elliptical galaxies are:

B. They are the most common galaxy type.

C. They typically contain very little gas and dust.

  • Elliptical galaxies are galaxies where you will find little or no gas and dust. The galaxies that are numerous in number are the elliptical galaxies.

  • In the elliptical galaxy, you can't find any <u>spiral component </u>in it.

Therefore, from the above explanation, we can see that <u>option B and C is the correct option.</u>

1. Driving at slower speeds than traffic flow _____________ .
r-ruslan [8.4K]

<u>The correct option is (D). The strength of electric field depends on the amount of charge that produces the field as well as the distance from the charge. </u>

<u> </u>

Further Explanation:

The electric field intensity at a point is the measure of the force exerted by a charge particle on another charge particle in the particular area of its strength.

The electric field intensity at a distance d due to a static charge having charge q is directly proportional to the amount of charge and inversely proportional to the square of the distance between them.

The Electric field intensity due to a charge is given as:

E = \dfrac{1}{{4\pi {\varepsilon _0}}}\frac{q}{{{r^2}}}

Here, E is the electric field intensity, q is the amount of charge and r is the distance of the charge from the point.

The above expression of electric field shows that the electric field intensity at a point depends on the amount of charge as well as the distance of the point from the charge.

<u>Thus, the correct option is (D). The strength of electric field depends on the amount of charge that produces the field as well as the distance from the charge. </u>

Which statement is true about a body moving at a constant speed in a circle?
Makovka662 [10]

Answer:

B

Explanation:

When something is moving at a constant velocity it's called the centripetal force. And the centripetal force accelerates radially outwards. It's like an ambulance siren. the sound waves are being exerted out into the atmosphere radiallly.

According to ohms law if you don't change the value of the resistor and you double the voltage in a circuit the amount of curren
padilas [110]

Answer: D (doubled)

According to ohm's law

                      I = V/R ,

                      V = IR ;   R = constant and V is doubled

  From the equation

                      V is directly proportional to the current, and it is given that R is constant ;

                    2V = 2I. R    since R = constant

                      Hence I is doubled.
