Answer: B. Bacteria in the plant converts nitrogen from the soil into molecules  that plants can use.

Explanation:

Root nodules are present in roots of plants which are in symbiotic relation with the nitrogen-fixing bacteria.

Nitrogen fixing bacteria fix nitrogen from the atmosphere and take up from the soil and convert into a form which is usable by the plants. These play an important role in nitrogen cycle.

How much force is needed to accelerate a 68 kilogram skier at a rate of 1.2m/sec
xxMikexx [17]

Let's use Newton's 2nd law of motion:

                                     Force = (mass) x (acceleration)

                                     Force = (68 kg) x (1.2 m/s²) =  81.6 newtons .

A student states, "The wave model is better than the particle model for electromagnetic radiation because it is easier to unders
Kobotan [32]

The student's claim did not follow the scientific method of discovery, hence, it is an opinion not a scientific claim.

<h3>What is the scientific method?</h3>

The scientific method is a procedure employed by scientific towards understanding the world around them as well giving explanation for phenomena in the natural world.

The scientific method involves:

  • observations
  • asking questions
  • putting forward a hypothesis
  • testing the hypothesis through experiments
  • analyzing results of the experiments and drawing conclusions
  • establishing a theory.

Since the student in question just put forward an opinion without testing it out using the scientific method, the statement is not a scientific claim.

If the PLATE SEPARATION of an isolated charged parallel-plate capacitor is doubled: A. the electric field is doubled
mash [69]

Explanation:

The electric field of an isolated charged parallel-plate capacitor is given by :

E=\dfrac{q}{A\epsilon_o}........(1)

Where

q is the electric charge

A is the area of cross section of parallel plate

It is clear from equation (1) that the electric field of a parallel plate capacitor is directly proportional to the charge on the plate and inversely proportional to the area of cross section of a plate.

So, the correct option is (E) i.e. "none of the above".

If a flea can jump straight up to a height of 0.410 m , what is its initial speed as it leaves the ground?
aivan3 [116]

Initial velocity = \(v_0\)

acceleration in the downward direction = -9.8 \(\frac {m}{s^2}\)

Final velocity at the highest point = 0

Maximum height reached = 0.410 m

Now, Using third equation of motion:

\(v^2 = {v_0}^{2} + 2aH

\(0^2 = {v_0}^{2} - 2 \times 9.8 \times 0.410

\({v_0}^{2} = 2 \times 9.8 \times 0.410\)

\(v_0 = 2.834 \frac {m}{s}\)

Speed with which the flea jumps = \(2.834 \frac {m}{s}\)
