How many paths do the electrons have to flowlin a series circuit?

1 answer:

4 0

One path because in a series circuit it is only one path while in a parallel circuit you have 2 or more. Our houses use parallel so that is why you can turn off one light and the rest would stay on.

a small asteroid of mass 125 kg is orbiting a planet that has a mass of 3.52x 10^13 what is the radial distance between the aste

asambeis [7]

Answer:

r = 2.031 x 10⁶ m = 2031 km

Explanation:

In order for the asteroid to orbit the planet, the centripetal force must be equal to the gravitational force between asteroid and planet:

Centripetal Force = Gravitational Force

mv²/r = GmM/r²

v² = GM/r

r = GM/v²

where,

r = radial distance = ?

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

M = Mass of Planet = 3.52 x 10¹³ kg

v = tangential speed = 0.034 m/s

Therefore,

r = (6.67 x 10⁻¹¹ N.m²/kg²)(3.52 x 10¹³ kg)/(0.034 m/s)²

What is the mirror formula for curved mirrors

Reika [66]

The mirror formula for curved mirrors is:
$\frac{1}{f}= \frac{1}{d_o}+ \frac{1}{d_i}$
where
f is the focal length of the mirror
$d_o$ is the distance of the object from the mirror
$d_i$ is the distance of the image from the mirror

The sign convention that should be used in order to find the correct values is the following:
- $f$ : positive if the mirror is concave, negative if the mirror is convex
- $d_i$ : positive if the image is real (located on the same side of the object), negative if it is virtual (located on the opposite side of the mirror)

What are 3 things that can affect gravity?

den301095 [7]

The force of gravity the masses exert on each other. If one of the masses is doubled , the force of gravity between the objects is doubled. Increases , the force of gravity decreases.
