C) refract

Explanation:

When light passes from air into water, the light waves will bend or they refract and the pencil will appear to be broken.

In normal space, light travels along a straight path with no alteration of the path along which it travels.

  • When light crosses the boundary from a denser to a less dense medium, it is refracted.
  • Refraction implies that the angle of the light is bent.
  • This is because the new medium causes the light rays to slow down compared to the speed it was coming forth with.

In your own words describe what free fall is
nekit [7.7K]

Answer:

u are falling

Explanation:

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.

An electron is trapped between two large parallel charged plates of a capacitive system. The plates are separated by a distance
Lorico [155]

Answer:

The electron will get at about 0.388 cm (about 4 mm) from the negative plate before stopping.

Explanation:

Recall that the Electric field is constant inside the parallel plates, and therefore the acceleration the electron feels is constant everywhere inside the parallel plates, so we can examine its motion using kinematics of a constantly accelerated particle. This constant acceleration is (based on Newton's 2nd Law:

F=m\,a\\q\,E=m\,a\\a=\frac{q\,E}{m}

and since the electric field E in between parallel plates separated a distance d and under a potential difference \Delta V, is given by:

E=\frac{\Delta\,V}{d}

then :

a=\frac{q\,\Delta V}{m\,d}

We want to find when the particle reaches velocity zero via kinematics:

v=v_0-a\,t\\0=v_0-a\,t\\t=v_0/a

We replace this time (t) in the kinematic equation for the particle displacement:

\Delta y=v_0\,(t)-\frac{1}{2} a\,t^2\\\Delta y=v_0\,(\frac{v_0}{a} )-\frac{a}{2} (\frac{v_0}{a} )^2\\\Delta y=\frac{1}{2} \frac{v_0^2}{a}

Replacing the values with the information given, converting the distance d into meters (0.01 m), using \Delta V=100\,V, and the electron's kinetic energy:

\frac{1}{2} \,m\,v_0^2= (11.2)\,\, 1.6\,\,10^{-19}\,\,J

we get:

\Delta\,y= \frac{1}{2} v_0^2\,\frac{m (0.01)}{q\,(100)} =11.2 (1.6\,\,10^{-19})\,\frac{0.01}{(1.6\,\,10^{-19})\,(100)}=\frac{11.2}{10000}  \,meters=0.00112\,\,metersTherefore, since the electron was initially at 0.5 cm (0.005 m) from the negative plate, the closest it gets to this plate is:

0.005 - 0.00112 m = 0.00388 m [or 0.388 cm]

Which statement is true regarding the circuit schematic below?
asambeis [7]

C. This is a direct current

<h3></h3><h3>What is schematic Current?</h3>

An electrical schematic is a diagram that shows how all of the wires and components in an electronic circuit are connected.

The ability to read electrical schematics is a really useful skill to have. To start developing your schematic reading abilities,

it’s important to memorize the most common schematic symbols.

Each physical component (i.e resistor, capacitor, transistor) has a unique schematic symbol.
