The statement 'Protons and Electrons attract each other because they are oppositely charged. Protons are positively charged, and electrons are negatively charged' is true.

<u>Explanation:</u>

Protons are positively charged particles while the electrons are oppositely charged and hence they both attract each other in an atom. Protons along with the neutrally charged neutrons are present inside the nucleus while the electrons are present in the outermost shells of an atom.

Moreover, precisely we can tell that both the protons and electrons attract each other due to the gravitational attraction inside the atom and the interaction between their internal electric charges and their magnetic fields.

Interestingly, there are equal number of protons and electrons inside an atom and hence an atom is usually neutral in charge. So, the given statement is right.

A group of organisms that is able to interbreed is called a
uranmaximum [27]

Answer:

D species

Explanation:

According to the most widely used species definition, the biological species concept, a species is a group of organisms that can potentially interbreed, or mate, with one another to produce viable, fertile offspring. In this definition, members of the same species must have the potential to interbreed.

a cepheid variable star is a star whose brightness alternately increases and decreases. suppose that cephei joe is a star for wh
MrRissso [65]

After one day, the rate of increase in Delta Cephei's brightness is;0.46

We are informed that the function has been used to model the brightness of the star known as Delta Cephei at time t, where t is expressed in days;

B(t)=4.0+3.5 sin(2πt/5.4)

Simply said, in order to determine the rate of increase, we must determine the derivative of the function that provides

B'(t)=(2π/5.4)×0.35 cos(2πt/5.4)

Currently, at t = 1, we have;

B'(1)=(2π/5.4)×0.35 cos(2π*1/5.4)

Now that the angle in the bracket is expressed in radians, we can use a radians calculator to determine its cosine, giving us the following results:

B'(1)=(2π/5.4)×0.3961

B'(1)≈0.46

A vertical wall (8.7 m x 3.2 m) in a house faces due east. A uniform electric field has a magnitude of 210 N/C. This field is pa
Dominik [7]

Answer:

\phi=4344.72Nm^2/c

Explanation:

From the question we are told that:

Dimension of Wall:

 (L*B)=(8.7 m * 3.2 m)

Electric field B=210 N/C

Angle \theta =42 \textdegree North

Generally the equation for electric Flux is mathematically given by

 \phi=EAcos\theta

 \phi=210*(8.7*3.2)*cos 42

 \phi=4344.72Nm^2/c

The pumping of air into and out of the lungs in known as
sineoko [7]

Answer:

Respiration

Explanation:

The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
