To test the hypothesis that plants grow faster in green light, a student set up 3 of the same type of plants. She placed the first plant under a green light, the second plant under a regular light bulb, and the third plant under a red light. What is the dependent variable in this experiment?

Answers


The dependent variable is the speed of plant growth, and the-plant's general health and welfare.

The hypothesis is defective.  It should talk about whether the plant is
DEPRIVED of any green light.  The way the experiment is described,
the results won't be clear.  The "regular" light bulb has a lot of green
wavelengths in it, along with a lot of other stuff that the plant may or
may not be interested in.  So the plant's response to the green light
AND the 'regular' light may be very similar.
 

An small asteroid with a mass of 6.25 x 1014 kg (almost 10 billion times less mass than the Earth) creates a force of 360 N on a nearby spacecraft that has a mass of 7.20 x 105 kg, how far apart are these two objects in km?

Answers

The Objects separated by gravitational force of 360 N, masses 6.25 × 10¹⁴ kg and 7.20 × 10⁵ kg. Applying Newton's law with G = 6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻² yields distance is 2.79139 km.

We can apply Newton's law of universal gravitation to calculate the distance between the two objects. The formula takes the form:

F = (G ⋅ m₁ ⋅ m₂) / r²

Where:

F represents the force between the two objects

G stands for the gravitational constant (6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²)

m₁ and m₂ denote the masses of the two objects

r indicates the distance between the centers of the two objects

Given that the force F = 360 N, m₁ = 6.25 × 10¹⁴ kg, and m₂ = 7.20 × 10⁵ kg, we can solve for r:

r² = (G ⋅ m₁ ⋅ m₂) / F

r = √((G ⋅ m₁ ⋅ m₂) / F)

Now, substituting the values and solving for r:

r = √(((6.67430 × 10⁻¹¹ m³ kg⁻¹ s⁻²) ⋅ (6.25 × 10¹⁴ kg) ⋅ (7.20 × 10⁵ kg)) / 360 N)

r ≈ 2791.39 m

Finally, converting the distance from meters to kilometers:

r ≈ 2.79139 km

Consequently, the two objects are approximately 2.79139 kilometers apart.

What is the closest universe to Earth?

Answers

"Universe" means "everything ... all space and all time".

So there's only one universe, we're in it, and the one that
we're in is the closest one.
As when know of right now, well... we actually don't know if there is a "multiverse". GOD knows, however, you should ask him.

A student wants to build a circuit with four light bulbs and one bell. A student wants to place a switch in the circuit so that only one light will still be on and the bell will still ring when the switch is opened

Answers

Answer:

we have an circuit with two branches in parallel,

* One formed by the switch and three light bulbs

* Another branch formed by a light bulb and the bell

Explanation:

For the construction of the circuit, let us analyze the conditions given, of the 4 light bulbs, only one should remain lit when the dapple is opened, so we must place three light bulbs and the switch in one branch and the other light bulb in the other branch.

For the bell to sound with the abort circuit it must be on the branch where the single bulb is.

Therefore we have an circuit with two branches in parallel,

* One formed by the switch and three light bulbs

* Another branch formed by a light bulb and the bell
