Electrostatic forces work on anything that is charged.
Usually only protons and electrons, but also some other elementary particles.

Answer:

d. a proton attracting an electron

Explanation:

Electrostatic force is the interaction between bodies that have electrical charges

a and b

The neutrons are particles that have no charge, therefore there are no electrostatic forces acting

Electrons are negatively charged particles and when they interact with each other they repel because they have the same charge

Electrons are particles with negative charge and protons with a positive charge, and when interacting with each other they attract because they have different charge

What is the approximate energy of a photon having a frequency of 4 x 10^7 Hz (h=6.6 x 10^-34]•s)

jok3333 [9.3K]

Answer:

E = 26.4 ×10⁻²⁷ j

Explanation:

Given data:

Energy of energy =?

Frequency = 4×10⁷ Hz

Solution:

Formula:

E = hf

E = 6.6 ×10⁻³⁴ m²Kg/s . 4×10⁷ Hz

Hz = s⁻¹

j = m²Kg/s ²

E = 26.4 ×10⁻²⁷ j.

Several methanol (CH3OH) dimers are drawn below, and several proposed intermolecular bonding interactions are highlighted in gre

Anon25 [30]

Answer:

Posible dimers structures: B) and D) (Figure 1)

Explanation:

The correct dimer structures are the ones that have a right intermolecular bonding interacction. In this case we will have hydrogen bonding. This type of interaction is due to the negative polarization in the oxygen and the positive polarization in the hydrogen. (Figure 2)

So, a correct dimer structure is posible if we have an interaction from the negative part (oxygen) to the positive part (hydrogen). The only structures that have this type of interactions are B and D.

The atomic mall mass is an element depends upon the.

Mama L [17]

The atomic mass of element has been dependent on mass of each isotopes and their abundance in nature.

The atomic mass has been the mass of neutrons and protons of the element. There has been the presence of the isotopes of the elements, with varying abundance, and varying atomic masses.

The atomic mass of the element has been the relative average atomic mass of the element with respect to the mass of the isotopes and their percent abundance.

The average atomic mass (amu) has been given by:

$amu=M_1A_1\;+\;M_2A_2$

Where, $M_1A_1$ has been the atomic mass and abundance of isotope 1.

$M_2A_2$ has been the atomic mass and abundance of isotope 2.

Thus, the average atomic mass has been dependent on mass of each isotopes and their abundance in nature.
