Answer: begins during adolescence

Explanation:

During puberty the testosterone hormone is released by the testes in males which initiates the process of spermatogenesis in males. The spermatogenesis is the process by which the maturation of the sperm cells in the testes takes place. The testes comprises of numerous thin, coiled tubules called as the seminiferous tubules. The each spermatozoa consist of head, middle body and short tail to swim and fertilize the female ovum.

15. The Energy possessed by a body by virtue<br>of its position or state is called :

shepuryov [24]

Answer:

The Energy possessed by a body by virtue of its position or state is called Potential energy.

Mathematically potential energy can be written as,

Potential energy = mgh

Where 'm' represents mass of the body, 'g' represents gravity of the earth and 'h' represents height of body. Potential energy depends on the height, higher the hight from the surface of the earth, maximum will be the potential energy.

What characteristics of EM waves did you discover?

jarptica [38.1K]

The characteristics of electromagnetic waves typically represent as follows:

There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values at the same time and place.
The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
The shape of electromagnetic waves is transverse waves.
It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
The universal constant of the velocity of electromagnetic waves in a vacuum is $\boxed{ \ c = 3 \times 10^8 \ m/s. \ }$
The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.

<h3>Further explanation</h3>

Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

The acceleration vector of a particle in projectile motion ________.

Alex73 [517]

Answer:

Points downward, and its magnitude is 9.8 m/s^2

Explanation:

The motion of a projectile consists of two independent motions:

- A uniform horizontal motion, with constant velocity and zero acceleration. In fact, there are no forces acting on the projectile along the horizontal direction (if we neglect air resistance), so the acceleration along this direction is zero.

- A vertical motion, with constant acceleration g = 9.8 m/s^2 towards the ground (downward), due to the presence of gravity wich "pulls" the projectile downward.

The total acceleration of the projectile is given by the resultant of the horizontal and vertical components of the acceleration. But we said that the horizontal component is zero, therefore the total acceleration corresponds just to its vertical component, therefore it is a vector with magnitude 9.8 m/s^2 which points downward.
