For a questions which involves constant acceleration, you can use the SUVAT equations.
S - displacement - -26.5m ( If you to take the right as a positive value - since displacement is a vector quantity involving direction and magnitude)
U
V - Final Velocity - unknown
A - Acceleration - -1.8m/s^2
T - Time - 3.81s
s = vt - 1/2at^2
-26.5m = 3.81v - 1/2 • -1.8 • 3.81^2
Rearrange
-26.5m/-1/2•-1.8•3.81^2=3.81v
3.81v = -2.028~
v = -0.532~ (3sf)
Answer:
2.93 x 10⁻⁴ volts
4.88 x 10⁻⁵ A
Explanation:
N = Number of turns in cylindrical coil = 400
r = radius of the coil = 2 cm = 0.02 m
Area of the coil is given as
A = πr²
A = (3.14)(0.02)²
A = 12.56 x 10⁻⁴ m²
ΔB = Change in magnetic field = 0.13 - 0.06 = 0.07 T
t = time interval = 2 min = 2 x 60 sec = 120 sec
Induced emf is given as
E = 2.93 x 10⁻⁴ volts
R = resistance of the resistor = 6 ohm
i = induced current
Using ohm's law
E = i R
2.93 x 10⁻⁴ = i (6)
i = 4.88 x 10⁻⁵ A
A visible white and red light indicate a second craft is coming from the starboard (right) side.
<h3>What is a navigation light?</h3>
A navigation light often referred to as a running light or position light, is a source of illumination aboard a ship, plane, or spacecraft that provides information about the location, course, or condition of the vehicle. Red and green navigation lights help with traffic control by indicating the orientation of the craft.
All navigation light systems typically comprise one or more white lights as well as red and green sidelights that designate the boat's port and starboard sides.
Having a flashlight on board is also essential since you never know when a navigation light may go out.
The typical navigational lights:
SidelightsSternlightMasthead lampoverall white lighting
Sidelights: Because they are visible to other vessels approaching from the side or head-on, these red and green lights are sometimes known as combo lights. The port (left) and starboard (right) sides of a ship are indicated by the red and green lights, respectively.
sternlight: Only from behind or almost behind the ship can one see the sternlight.

Every atom has electrons. When you add new electrons to the wire, they will be passed on to an atom. The electrons keep passing from atom to atom until it reaches the light source, basically. It's kinda like that one song "100 jugs of milk" or whatever it's called. Each atom passes the atom next to it an electron.
Answer:
Electric field = 8.6364 × 10⁶ V/m
Explanation:
Given that:
The Voltage across the cell membrane = 76.0 mV
Also, 1 mV = 0.001 V
So, Voltage = 0.076 V
Given the thickness of the membrane = 8.80 nm
Also, 1 nm = 10⁻⁹ m
So, Thickness = 8.80 × 10⁻⁹ m
The expression for electric field is shown below as:
Electric field = 8.6364 × 10⁶ V/m
