According to the Aufbau principle,

1 answer:

3 0

The correct answer is A, electrons enter orbitals of lowest energy first. The Aufbau principle states that electrons orbiting atoms fill the lowest energy levels available before filling higher levels. Following this, molecules can go into the most stable electron configuration.

In the future, people will only enjoy one sport: Electrodes. In this sport, you gain points when you cause metallic discs hoveri

Answer:

Disk C and Disk D

Explanation:

The total charge in the disks

$q_1 + q_2 = q_{total}$

must be conserved before and after bringing them together.

Lets equate the sum of the initial charge with the sum of the final for the disk:

$q_{1_i} + q_{2_i} = q_{1_f} + q_{2_f} = 2 * (+8.5) \mu C$

$q_{1_i} + q_{2_i} = +17 \mu C$

So, the initial charges must sum +17 μC.

Now, as there are no charges over +17 μC, this means that both charges must be positive.

As the only positive charges are $q_C$ and $q_D$ , this disk must be the ones we are looking for. And, as we can see, they sum 17 μC:

$q_{C} + q_{D} = 5 \mu C + 12 \mu C = 17 \mu C$

A rope is wrapped around a pulley many times. The pulley can be modeled as a solid disk of radius R and mass M, and a mass mA ha

aleksandr82 [10.1K]

The magnitude of the tangential acceleration of the hanging mass is 2mg/MR

<h3>Tangential acceleration of the hanging mass</h3>

The tangential acceleration of the hanging mass around the pulley is determined from the principle of conservation of angular momentum as shown below;

τ = Iα

Where;

I is the moment of inertia
α is the angular velocity

$\alpha = \frac{\tau}{I} \\\\\alpha = \frac{mgR}{3/2MR^2} \\\\\alpha = \frac{2mgR}{3MR^2} \\\\\alpha = \frac{2mg}{3MR}$

Where;

m is the hanging mass
M is the mass of solid disk

The tangential acceleration is calculated as follows;

$a = \alpha R\\\\a = \frac{2mg}{3MR} \times R\\\\a = \frac{2mg}{3M}$

Thus, the magnitude of the tangential acceleration of the hanging mass is 2mg/MR
