The nuclear charge an electron actually experiences is called the effective nuclear charge. This charge is always less than the

actual nuclear charge since in a many-electron system the electrons. True or false?
Physics

Vesna [10]3 years ago

Answer:

True

Explanation:

This charge becomes less because of interference of other electrons because of which a portion of positive charge on nucleus is cancelled out thus resulting in decrease of force due to negative charge on an electron and a portion reduced positive charge on nucleus. Thus an electron experiences an effective nuclear charge which is less than the actual nuclear charge if other electrons were not present. This effect is called electrom shielding -- True!

What is the kinetic theory of matter? How does it relate to the motion of molecules?
Charra [1.4K]

Answer:

Explanation:

Kinetic energy is energy that an object has because of its motion. The Kinetic Molecular Theory explains the forces between molecules and the energy that they possess. This theory is based on three theories about matter. Matter is composed of small particles (atoms, molecules, and ions).

marshall27 [118]

Answer:

x = 2000 Km

Explanation:

Given

y = 10 km

Slope: 1 : 200

x = ?

We can apply the formula

y / x = 1 / 200   ⇒     x = 200*y = 200*10 Km

⇒     x = 2000 Km

Explain whether demand is likely to be elastic or inelastic for Big Macs. A. Elastic comma since many other fast food items coul
anyanavicka [17]

Answer:

A - elastic since many other fast food items could be considered close substitutes.

Explanation:

The price elasticity of demand is how much the demand of the Big Macs will change due to a 1% change in price. Should the elasticity be greater than 1, the Big Macs will be elastic. Should it be less than 1, the Big Macs are inelastic.  

Demand elasticity is calculated as the percentage change in quantity demanded divided by a percentage change in price.

Since Big Macs are (i) a luxury good, and (ii) have close substitutes (other burgers available at McDonalds and other fast food stores), we will say their elasticity is greater than 1.  

This means that the demand of Big Macs will change due to a 1% increase in price due to the presence of close substitutes.
