Answer:

Option 2. √3 x V

Explanation:

Let the velocity of satellite orbiting Earth at r be V

Let the velocity of the satellite orbiting at 3r be V1

V (orbiting at r) = √(2gr)

V1 (orbiting at 3r) = √(2g3r)

Now let us find the ratio of V1(orbiting at 3r) to V(orbiting at r) .

This is illustrated below

V1 / V = √(2g3r)/√(2gr)

V1 / V = √3

Cross multiply to express in linear form

V1 = V x√3

V1 = √3 x V

From the above illustrations, we can see that the velocity of the satellite when it is moved to an orbital radius of 3r is: √3 x V

These diagrams show two atoms of fluorine and an atom of magnesium.
Bezzdna [24]

the answer is D. A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion

because magnesium only has 2 valence electrons, and it would be easier to lose electrons rather gain.

i just took the test, its right.

All household circuits are wired in parallel. A 1140-W toaster, a 270-W blender, and a 80-W lamp are plugged into the same outle
VARVARA [1.3K]

Answer:

total current = 12.417 A

so it will not fuse as current is less than 15 A

Explanation:

given data

toaster = 1140-W

blender = 270-W

lamp = 80-W

voltage = 120 V

solution

we know that current is express as

current = power ÷ voltage   ......................1

here voltage is same in all three device

so

current by toaster is

I = \frac{1140}{120}

I = 9.5 A

and

current by blender

I = \frac{270}{120}

I = 2.25 A

and

current by lamp is

I = \frac{80}{120}

I = 0.667 A

so here device in parallel so

total current is = 9.5 A + 2.25 A + 0.667 A

total current = 12.417 A

so it will not fuse as current is less than 15 A
