Answer:

The orbital diagram represents the filling of electrons in the sub levels of an orbit. The filling of the orbitals in sub- levels follow some basic rules and principles.

The orbital diagram of an orbit containing 16 electrons will be as follows:

1s²2s²2p⁶3s²3p⁴

The maximum number of electrons in each sublevel of the orbitals are:
2 electrons for s-sublevel with one orbital
6 electrons for p-sublevel with three orbital
10 electrons for d-sublevel with five orbital
14 electrons for f-sublevel with seven orbital

In the article, what is the result of the conflict between the American public and the U.S. Food and Drug Administration (FDA)?

user100 [1]

Food and drug administration (FDA) is used for protecting the public health in safety, security, drugs, biological products, and medicinal devices.

Explanation:

The U.S food and Drug Act tells about the sale of misbranded or adulterated food and drugs in interstate commerce and had a foundation for the nation's first consumer protection agency.

The federal law is passed to establish the quality standards for foods, drugs and medical devices manufactured and sold in U.S.

This act has a new consumer protection against unlawful cosmetics and medical devices and enhances the government's ability to enforce the law. The main goal of FDA is to make food and drug safe for public consumption.

A tennis ball of mass m=0.060 kg and speed v=25 m/s strikes a wall at a 45 angle and rebounds with the same velocity at 45°. Wha

Diano4ka-milaya [45]

To solve this problem we will apply the concepts related to the Impulse which can be defined as the product between mass and the total change in velocity. That is to say

$p = m\Delta v$

Here,

m = mass

$\Delta v =$ Change in velocity

As we can see there are two types of velocity at the moment the object makes the impact,

the first would be the initial velocity perpendicular to the wall and the final velocity perpendicular to the wall.

That is to say,

$v_i = vcos\theta$

$v_f = -v sin\theta$

El angulo dado es de 45° y la velocidad de 25, por tanto

$v_i = (25)cos(45) = 17.68m/s$

$v_f = -(25)sin(45) = -17.68m/s$

The change of sign indicates a change in the direction of the object.

Therefore the impulse would be as

$p = 0.060(-17.68-17.68)$

$p = -2.12kg \cdot m/s$

The negative sign indicates that the pulse is in the opposite direction of the initial velocity.

Is it possible for the momentum of a system consisting of two carts on a low-friction track to be zero even if both carts are mo

tamaranim1 [39]

Answer:

Yes, if the carts are travelling into opposite directions

Explanation:

The total momentum of a two carts system is the sum of the momenta of the individual carts:

$p=p_1 +p_2 = m_1 v_1 + m_2 v_2$

where

m1, m2 are the masses of the two carts

v1, v2 are the velocities of the two carts

In order to have a total momentum of zero, we must have

$m_1 v_1 + m_2 v_2 = 0\\m_1 v_1 = - m_2 v_2$ (1)

Let's remind that velocity (and so, momentum as well) is a vector quantity: this means that it has a direction, so when summing together the momenta, we must also consider the sign of the velocity, depending on its direction.

Therefore, if the two carts are moving in opposite directions, the signs of the two velocities will be opposite. For example, we can have

$v_1 > 0 \\v_2 < 0$

This means that the condition in eq.(1) can be satisfied, provided that the two carts are travelling into opposite directions.
