<h3>Answer:</h3><h3>B.one coulomb</h3>

<h3>Explanation:</h3><h3>It takes an enormous number of electrons to equal one coulomb.In fact,it takes about 6.2x10¹⁸.Looking at this from the opposite perspective,one electron has a negative charge equal to -1.6x10¹⁹ coulombs.</h3>

The position-time equation for a certain train is
astraxan [27]

Answer:

a=4.8m/s^2

Explanation:

Hello,

In this case, since the acceleration in terms of position is defined as its second derivative:

a=\frac{d^2x(t)}{dt^2}=\frac{d^2}{dt^2}(2.9+8.8t+2.4t^2)

The purpose here is derive x(t) twice as follows:

a=\frac{d^2x(t)}{dt^2}=\frac{d}{dt}(8.8+2*2.4*t)\\ \\a=4.8m/s^2

Thus, the acceleration turns out 4.8 meters per squared seconds.

Best regards.

You are in a canyon and yell across. It takes 4 seconds for the
Naya [18.7K]

Answer:

Width = 680 [m]

Explanation:

To solve this problem we must know the speed of sound in the air, conducting an internet search, we find that this speed has a value of v = 340 [m/s].

We apply the following kinematic equation, which relates space to time, to define speed.

v = x /t

where:

x = distance [m]

t = time [s]

v = velocity [m/s]

Now replacing:

x = 340 * 4

x = 1360 [m]

But the width of the cannon is calculated when the sound wave hits the wall of the canyon, so this width is half the distance.

Width = 1360 / 2 = 680 [m]

explain how metamorphic rocks are formed, and explain the differences between regional and contact metamorphism?
Igoryamba
Metamorphic rocks form when pre-existing or parent rocks (whether igneous, sedimentary, or even metamorphic) are altered by heat, pressure, and the chemical activity of fluids. When the dominant altering factor is heat, usually  from direct contact , it may undergo fundamental change  in texture and recrystallization is called contact metamorphism. While regional metamorphism,  where rocks texture and minerals are changed by heat and pressure.
