The speed of a periodic wave disturbance is 2.45 m/s.
<u>Explanation:</u>
Sound waves travel as sinusoidal nature. And the distance between the two successive crests or troughs are determined as the wavelength of the sound wave.
Similarly, the measure of number of complete cycles in a given time is defined as frequency of sound wave. The speed of any wave is determined as the product of wavelength of transmission of wave and frequency of that wave.
Thus,
×
So,
× = 2.45 m/s.
Thus, the speed of periodic wave disturbance is 2.45 m/s.
Male reproductive system
Type of sex cell = gamete or sperm
Where sex cells are produced = testes
Tubes that sex cells = The sperm move into the epididymis, where they complete their development. The sperm then move to the vas deferens (VAS DEF-uh-runz), or sperm duct. The seminal vesicles and prostate gland make a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated.
Where sex cells exists the body = It exits the penis, through the urethra, during ejaculation. Testicles (testes) – oval sex glands located in a skin sack called the scrotum. Sperm and sex hormones are made by the testicles.
Structure where the primary sex = Testicles (testes)
The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules.
Primary sex hormone= sperm
Where an egg= The egg cell is swept through the fallopian tube, which runs from the ovary to the uterus. The egg cell slows in the longest and widest part of the fallopian tube. This is where the egg cell is fertilized by a man's sperm cell.
Where a fertilized egg= Fertilization of an egg by a sperm normally occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants to the uterine lining.
Where the exchange = The placenta is the organ through which gases, nutrients, and wastes are exchanged between the maternal-fetal circulations.
Female reproductive system
Type of sex cells = the egg or ovum
Where sex = At the upper corners of the uterus, the fallopian tubes connect the uterus to the ovaries. The ovaries are two oval-shaped organs that lie to the upper right and left of the uterus. They produce, store, and release eggs into the fallopian tubes in the process called ovulation (av-yoo-LAY-shun).
Tubes that sex cells = During sex, sperm cells travel through the vagina to the uterus and fallopian tubes. In the fallopian tube, the sperm meets the egg that was released from the ovary during ovulation.
Where sex cells = The vagina serves three purposes: It's where the penis is inserted during sexual intercourse. It's the pathway (the birth canal) through which a baby leaves a woman's body during childbirth. It's the route through which menstrual blood leaves the body during periods.
Structure where the primary = Two groups of female sex hormones are produced in the ovaries, the estrogens and progesterone. These steroid hormones contribute to the development and function of the female reproductive organs and sex characteristics.
Primary sex hormone = Estrogen is the major female hormone. The lion's share comes from the ovaries, but small amounts are produced in the adrenal glands and fat cells.
Where an egg = A pregnancy starts with fertilization, when a woman's egg joins with a man's sperm. Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
Where a fertilized egg = Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.
Where the exchange = The placenta contains a complex network of blood vessels that allow the exchange of nutrients and gases between the mother and the developing fetus.

The zero tolerance law applies to drivers <u>under the age of 21.</u>
<h3>Zero Tolerance Law:</h3>
Drivers under the age of 21 who operate a motor vehicle with a BAC of between 0.02% and 0.07% are subject to what is known as the "Zero Tolerance Law." The Zero Tolerance Law aims to prevent underage drivers from driving after consuming alcohol.
The zero-tolerance rule states that it is against the law for anyone under the age of 21 to operate a motor vehicle while having any detectable level of alcohol in their system. Zero Tolerance Law states that a minor has committed the criminal offense of DUI if there is ANY detectable level of alcohol in his or her system while operating a vehicle in public. The minor's driver's license is immediately suspended, and the officer has the authority to confiscate the license on the spot.

#SPJ4
Answer:
Explanation:
a ) 12.0 lbs - mass
b ) .34 g - mass
c ) 120 kg - mass
As lbs , g and kg are units of mass , these things represent mass . lbs is FPS unit of mass and kg is SI unit . g is CGS unit of force .
d ) 1600 kN It represents force because kN or kilonewton is unit of force .
e ) it represents , length or distance because m or metre is unit of length .
f ) 411 cm It represents length or distance because cm is smaller unit of length
g ) 899 MN or million newton . Like d ) It also represents force . Million newton is higher unit of force .
