Vehicle Kinematics: a vehicle sliding sideways into a gravel pit, a vehicle driving down a bank, a vehicle driving up a ramp and a vehicle sliding laterally against a curb.  "sliding laterally against a curb" and "sliding sideways into a gravel pit".

Answer:

We can find the difference using the definition of each concept.

First of all, kinematics refer to a subfield of classical mechanics that only DESCRIBES the motion of a body, point or any object.

Now, vehicular kinematics refer to the study of the motion of a vehicule, only to describe the movement. This subject is studied to test vehicules. Vehicular kinematics and vehicule dynamics are two important fields to analyse in vehicules production, to improvement them in case of accidents. It's important to specify that all these studies are only about the car itself.

On the other hand, we have occupant kinematics which refer to the study of the motion of the occupant who is inside the vehicle. This study is aimed to calculate the movement of the occupant in case of accidents, in order to prevent serious injuries. The best example for this is the air bag, which is an invention to prevent major injuries in case of accidents, this innovation was developed by analysing the motion of the occupant to see where the body goes and which part of the body hits the car inside. The air bag represents a simple but useful innovation that prevents many death per year in car accidents.

Therefore, basically, the difference between these two kinematics is that one studies the vehicle motion and the other one studies the occupant motion, the person inside the vehicle. These studies are important to develop and innovate new things to prevent accidents or serious injuries after an accident.

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.

A certain lightbulb has a tungsten filament with a resistance of 26 Ω when cold and 170 Ω when hot. If the equation R = R0 [1 +
iris [78.8K]

Answer:

Explanation: The equation that relates resistance of tungsten at different temperatures is as follows

R = R₀ [1 + α ∆T]  , R₀ is resistance at lower temperature , R is resistance at higher temperature . α is temperature coefficient of resistivity and ∆T is rise in temperature .

Putting the values

170 = 26 [1 + .0045 ∆T]

∆T = 1230.75

lower temperature = 40◦C

higher temperature = 1230 + 40

= 1270◦C
