Answer: D.  estrogen and progesterone

Explanation:

Puberty is a transitional phase from childhood to adulthood. It is initiated by the certain hormone production which are responsible for bringing changes in the physiology and morphology of the child which leads to the development of features which are found in adults like development of breasts in girls and development of beard and chest hair in boys.

The estrogen hormone secretes in females during puberty. It is responsible for the development of breasts, helps in development of the vagina, fallopian tubes and uterus. The progesterone helps in initiation and maintenance of the mensuration cycle.

A gargoyle statue falls off the side of a building from a height of 75 m . How long did it take to reach the ground
disa [49]

Distance of a fall from rest = (1/2) (g) (Time²)

75 m = (1/2) (9.8 m/s²) (Time²)

75 m = (4.9 m/s²) (Time²)

Divide each side by (4.9 m/s²):

Time² = (75 m) / (4.9 m/s²)

Time² = (15.3) (s²)

Square-root both sides:

<em>Time = 3.91 seconds</em>

Suman climb a 5 metre high ladder in 10 second calculate his power the mass of his body is 50 kg​
nadezda [96]

Answer:

245W

Explanation:

Given parameters:

Mass of his body = 50kg

Height of climb  = 5m

Time  = 10s

Unknown:

Power = ?

Solution:

Power is defined as the rate at which work is done;

 Mathematically,

           Power  = \frac{work done}{time}

  Work done  = mgh

m is the mass

g is the acceleration due to gravity

h is the height

  Work done  = 50 x 9.8 x 5  = 2450J

 

          Power  = \frac{2450}{10}   = 245W
