<span> answer>>>>electric force <<<<by the way i don't like physics but i answer this for you ^-^</span>

<span>This is because centripetal force is just the net force of a circular motion. There are no attractive or repulsive forces here. This is not the case here. </span>
<span>The gravitational force is a force reliant on mass and attraction of the masses. There are attractive forces here, but not really repulsive forces. </span>
<span>The electric force is the only one that would make sense because it has to do with a relationship between charges and includes both repulsive and attractive forces.</span>

evablogger [386]

Answer:

Explanation: light waves against itself, which leads to internal interference of different wave component Which is also referred to as diffraction.

Diffraction causes beam of light to slowly spread out as it travels, so that some of the light will bend away from a straight line motion of the main part of the wave

(Serway 9th ed., 9-3) At one instant, a 17.5-kg sled is moving over a horizontal surface of snow at 3.50 m/s. After 8.75 sec has

Scrat [10]

Answer:

F = 7 N

Explanation:

given,

mass of sled = 17.5 Kg

speed of snow on horizontal surface = 3.5 m/s

time taken to stop = 8.75 s

initial momentum

= m U

= 17.5 x 3.5 = 61.25 Kg.m/s

final momentum

final velocity = 0 m/s

final momentum = 0

impulse = change in momentum

impulse = force x time

equating both the formula of impluse

F x t = 61.25 - 0

F x 8.75 = 61.25

F = 7 N

Force acting on the moving sled is equal to F = 7 N

A plastic ball in a liquid is acted upon by its weight and by a buoyant force. The weight of the ball is 4 N. The buoyant force

Sauron [17]

Answer:

The acceleration is 2.448 meters per square second and is vertically upward.

Explanation:

The Free Body Diagram of the plastic ball in the liquid is presented in the image attached below. By Second Newton's Law, we know that forces acting on the plastic ball is:

$\Sigma F = F - m\cdot g = m\cdot a$ (1)

Where:

$F$ - Buoyant force, measured in newtons.

$m$ - Mass of the plastic ball, measured in kilograms.

$g$ - Gravitational acceleration, measured in meters per square second.

$a$ - Net acceleration, measured in meters per square second.

If we know that $F = 5\,N$ , $m = 0.408\,kg$ and $g = 9.807\,\frac{m}{s^{2}}$ , then the net acceleration of the plastic ball is:

$a = \frac{F}{m} - g$

$a= 2.448\,\frac{m}{s^{2}}$

The acceleration is 2.448 meters per square second and is vertically upward.

Sequence the steps involved in the working of a doorbell. *

Alenkasestr [34]

Answer:

How doorbell chime works?

A simple chime doorbell uses the magnetic field created by the electromagnet to move a magnetic piston to strike two tone bars. ... When the button is pressed, the circuit closes and the electromagnet moves a contact arm. When the contact arm moves, it interrupts the circuit and the electromagnet stops.
