Answer:

<h2>They both include a question, procedure and conclusion.</h2>

Explanation:

Both type of investigations include a question, procedure and conclusion. Actually, <em>these three elements are standard for any type of investigation.</em>

All investigation are developed based on a problematic situation which defines a question, that the investigator seek to answer. In the attempt of answering, he develop several procedure according to the methodology of the investigation, that is, a descriptive and comparative investigation have different procedures, to seek a similar purpose, to answer the question.

After developing all procedures needed according to the methodology, a conclusion is made, based on the facts from the procedure. This conclusion is the actual attempt to answer the question, having two possible outcomes, or the problem in the question is solved, or just the procedure and methodology couldn't do it that far.

En resume, those are elements of both type of investigation.

Therefore, the right answer is the first one.

Anon25 [30]

The block has the greatest average power provided is bock m.

<h3>What is instantaneous power?</h3>
  • This is the product of force and velocity exerted on an object.

Mathematically instantaneous power is calculated as;

P = Fv

where;

  • F is the applied force
  • v is the velocity

Both blocks (m and 2m) will experience the same force but different velocity.

The smaller block (m) will experience greater velocity.

Thus, the block has the greatest average power provided is bock m.

Define moment of momentum. at which condition is it's magnitude zero?​
ololo11 [35]

Let's start with the concept of momentum. What is it? Linear momentum in physics is mathematically written as a product of mass and velocity of an object. Now let us suppose a body of mass m is moving in an inertial frame of reference with velocity v. Consider the fact that no external force is acting on the system. The momentum of this body is given by mv, where m is the mass and v is its velocity. In case of simple real world problems not delving into the realms of relativity, mass is a conserved quantity and it cannot be zero. Hence the velocity of the body must be zero and hence the momentum.

However, photons are considered to have a rest mass zero.

However note the point carefully "rest mass". A body in motion cannot have mass to be zero.

Why does a vibrating simple pendulum not to produce any sound
Gelneren [198K]
It does produce 'sound' ... a compression wave traveling through the air. But your ears don't hear a sound that's vibrating less than 20 or 30 times every second. If you could swing your pendulum that fast, you could hear the sound of its vibrations pushing the air around.
