In a pulley system, two blocks are connected by a rope as shown below. The coefficient of static friction between block A and th
umka21 [38]

Hi there!

We can begin by doing a summation of forces for each block.

Block A:

This block has the force of tension (in direction of acceleration +) and static friction (opposite direction -) acting on it. Thus:

\Sigma F_A = T - F_s\\\\m_Aa = T - \mu m_Ag

Block B:

This block has the force of tension (opposite of acc. -) and gravity (in direction of acc +), working on it.

\Sigma F_B = m_Bg - T\\\\ m_Ba = m_Bg - T

Add both of the expressions and solve for the maximum mass of Block B.

\Sigma F = m_Bg - T + T - \mu m_Ag\\\\a(m_A + m_B) = m_Bg - \mu m_Ag

To find the minimum value, we can set a = 0, so:

0 = m_Bg - \mu m_Ag\\\\\mu m_Ag = m_B g\\\\0.8(20)(9.8) = m_B (9.8)\\\\m_B = \frac{0.8(20)(9.8)}{9.8)} = \boxed{16 kg}

The block must weigh <u>> 16 kg</u> for block A to move.

An object is in circular motion how will the object behave if the centripetal force is removed
Monica [59]

If the force is removed, then there are no other forces acting on the object, the object will continue to move at constant velocity, meaning that it would move in a line tangent to the circular path.

zheka24 [161]
I believe the correct answer would be A. The extraction of oil shale is detrimental to the environment mainly because the process of extraction requires large amounts of land. Lands are being excavated in order to locate areas which contains the oil. This is not good since it affects ecosystems and destroy habitats.

TEA [102]

Answer:

Asking a question

Research existing sources

Define an hypothesis

Design and conduct a study

Draw conclusion

Report result.

Explanation:

Scientific study simply means establishing the existence or proving the veracity of an hypothesis, hence making it a fact. A scientific study follows an orders set of procedure;

Asking a question is the first step as this is what prompts the research, question usually stems after making an observation.

The a observation made and question asked will lead to making research on the observed phenomenon, this is to check if such question has been asked in the past and maybe any scientific study as been carried out in the past.

To make research further, an hypothesis is defined in a bid to find more evidence to support one's observation through experiment.

Study design and implementation is next as the type of study to be embarked upon will determine which type of design preparation and study pattern to deploy.

Conclusion a d report of observations made are the last part of a scientific study which is key as all outcomes of the study should be adequately detailed in an understandable format while also ensuring reproducibility.
