Significant think why scientists presently accept is the key factor in moving information from short term memory is to deliver more the data which is rehashed or utilized, the more probable it is to end up in long-term memory.

Explanation:

Short-term memory (STM) envelops psychological capacities for the capacity, support, and mental control of data that is never again present in the tactile condition. So the Magic number 7 (give or take two) gives proof to the limit of transient memory.

Most grown-ups can store somewhere in the range of 5 and 9 things in their transient memory. It enables the apparent thing important to be changed over into a development that can be put away inside the brain, and afterward reviewed later from the present moment or long-term memory.

A wire of length L is wound into a square coil with 167 turns and used in a generator that operates at 60.0 Hz and 120 V rms val

Mrac [35]

Answer:

$171.43m$

Explanation:

First, define $emf$ ( electromotive force )-is the unit electric charge imparted by an energy source. In this case the generator.

The peak emf is:

$E_p_e_a_k=\sqrt2(E_m_a_x)$ = $\sqrt(2\times 120V)=170V$

Substituting $w=2\pi f$ and the value for peaf $E$ gives:

Total length= $4\sqrt {\frac{NE_p_e_a_k}{Bw}$ = $4\sqrt{\frac{167\times 170}{0.041T\times 2pi \times 60.0Hz}$

= $171.43m$

Hence, wire's length is 171.43m

What is the comparison of Wind turbine and other energy sources?

egoroff_w [7]

Wind is a more efficient power source than solar. Compared to solar panels, wind turbines release less CO2 to the atmosphere, consume less energy, and produce more energy overall.

A thin uniform disk of mass m and radius r has a string wrapped

olasank [31]

The magnitude of the weight of the disk is greater than the magnitude of the tension force of the string. ((c) $F_{T} < F_{g}$ )

<h3>How to analysis a rigid body on dynamical condition</h3>

A rigid body is a system whose geometry cannot be neglected and in which deformations due to external forces applied on the system are negligible.

In this question we need to establish a free body diagram with all critical forces and motion conditions. There are two external forces: (i) tension ( $F_{T}$ ), (ii) weight ( $F_{g}$ ), both in newtons.

The disk falls due to gravity and rotates around the string in a case of rolling, which combines rotation and translation. By Newton's laws of motion we have the following expression:

$\sum F = -F_{g}+F_{T} = -m\cdot R\cdot \alpha$ (1)

Where:

$m$ - Mass of the disk, in kilograms.
$\alpha$ - Angular acceleration, in radians per square second.

By algebra we derive the following relationship between the two forces:

$-F_{g} = -F_{T}-m\cdot R\cdot \alpha$

$F_{g} > F_{T}$

Therefore, the magnitude of the weight of the disk is greater than the magnitude of the tension force of the string. ((c) $F_{T} < F_{g}$ ) $\blacksquare$

<h3>Remark</h3>

The statement is incomplete and poorly formatted. Correct and complete form is shown below:

A thin uniform disk of mass m and radius r has a string wrapped around its edge and attached to the ceiling. The bottom of the disk is at height 3R above the floor, as shown above. The disk is released from rest. The rotational inertia of a disk around its center is $I = \frac{1}{2}\cdot M\cdot R^{2}$ .

When released from rest, the disk falls and the string unwinds. The force that the string exerts on the disk is $F_{T}$ , and the gravitational force exerted on the disk is $F_{g}$ . Which of the following expression correctly relates $F_{T}$ and $F_{g}$ as the disk falls?

(a) $F_{T} > F_{g}$ , (b) $F_{T} = F_{g}$ , (c) $F_{T} < F_{g}$
