False, because hypochondriacs think they have a significant, undetected medical ailment even when testing reveal they are healthy.
Who are hypochondriacs?A hypochondriac is someone who, despite diagnostic testing showing they have no health issues, lives in constant anxiety that they have a terrible, undetected medical illness. They are obsessed with the concept that they suffer from a major illness that has gone untreated.
In adults, hypochondriasis often begins to manifest. Among the symptoms are a persistent, strong anxiety of developing a major illness and concern that seemingly little symptoms portend a larger problem. A patient may change physicians or see them regularly.
Medication and counselling could be helpful.

Eiman connects eight 12Ω lamps in series. What is
the total resistance of the circuit?
please help
Answer:
Total resistance is 96 ohm
Explanation:
Rs = R1 +R2 + R3 + R4 + R5 +R6 + R7 + R8
where R1 is lamp 1
R2 is lamp 2 n so on
Rs = 12 + 12 +12 + 12 +12 + 12 + 12 + 12( as each lamp is of resistance 12)
Rs = 96 ohm

Bill and Nageen have each built an electric motor and they are testing them by having them lift boxes. Bill's motor lifts a box 0.39 metres in 2 seconds. Nageen's motor lifts the same box 0.35 metres in 2 seconds. Whose motor has applied more power to the box?
Answer:
Bill's motor
Explanation:
Bill's motor lifts a box 0.39 metres in 2 seconds.
Nageen's motor lifts the same box 0.35 metres in 2 seconds.
Power = Work done/time
or
[tex]P=\dfrac{mg\times h}{t}[/tex]
Power of bill's motor,
[tex]P_1=\dfrac{m\times 9.8\times 0.39}{2}\\\\P_1=1.91m\ Watts[/tex]
Power of Nageen's motor,
[tex]P_2=\dfrac{m\times 9.8\times 0.35}{2}\\\\P_2=1.71m\ Watts[/tex]
So, Bill's motor applied more power to the box.

State the Law of Electric Charges in your own words.
[tex] \\ [/tex]
According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.
Things that are negatively charged and things that are positively charged pull on (attract) each other. This makes electrons and protons stick together to form atoms. Things that have the same charge push each other away (they repel each other). This is called the Law of Charges.

Why is visible light safe to humans ?
Explanation:
Visible light is the range of electromagnetic waves that humans can see. Anything that glows or gives off light makes waves of what we call visible light. The sun, light bulbs, candles and fire are all things that people automatically think of when it comes to light, but visible light comes from many sources and in many colors. Some other sources of visible light include: television and computer screens, glow sticks, and fireworks
Answer:
Visible light is visible because most of the gases in planetary atmospheres (oxygen, nitrogen, carbon dioxide, methane, ammonia…) are transparent to those wavelengths. We evolved to see those wavelengths because the atmosphere in visible light is transparent.

How do we know when an object is in static or dynamic equilibrium?
Answer:
First Condition of Equilibrium
Explanation:
This means that both the net force and the net torque on the object must be zero. The condition Fnet=0 F net = 0 must be true for both static equilibrium, where the object's velocity is zero, and dynamic equilibrium, where the object is moving at a constant velocity.The sum of the forces on it in each direction is zero. The sum of the torques on it in each direction is zero. Its linear momentum is zero.The diagram below shows a wave. The feature of the wave are labeled A, B, C, and D. Which label identifies the wavelength?
According to the given diagram, the c identifies the wavelength of the curve. Hence, option C is correct.
What is wavelength?In order to characterize waveform signals that are transmitted across wires or into space, the term "wavelength" is used to refer to the separation between two identical positions (adjacent crests) in succeeding cycles. Typically, this length in wireless systems is measured in meters (m), centimeters (cm), or millimeters (mm) (mm). When describing the wavelength of infrared (IR), visible light (UV), and gamma radiation, units of 10-9 nanometers (nm) or angstroms (10-10 m) are more usually used.
The relationship between frequency and wavelength is inverse, with frequency being the number of wave cycles per second. A signal's wavelength shortens as its frequency rises, or we may say that the relationship between wavelength and refractive index is inverse.

If you were in charge of designing a wire to carry electricity across your city, state or province, which of
the following properties would be most important for your wire to have?
Should it be thick or thin, aluminum or nichrome, buried underground or installed out in the sun
Pleaseeee I need this done I beg Ill give brainiest and make sure its at least on paragraph if not then at least as many sentences as you can please
Answer:
Thin, aluminium and buried underground.
Explanation:
When it comes to electrification of a state or province, some characteristics of the wire to use must be considered. This would help to minimize and avoid power loss and wire burns.
i. The wire to use should be thin, and a quite number can be twisted one against the other so as to increase the surface area for heat dissipation.
ii. Aluminium wire is more preferable for this project. It has a high melting point, and reduces energy loss.
iii. Burying the wire underground through an insulator is the best choice, though expensive but would preserve the wire from external influence.
Sally's mass on Earth is 50 kg. What is her mass on the moon?
Answer:
Being that the moon has a gravitational force of 1.622m/s 2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon. Conversely, a person is 83.5% heavier on earth than on the moon.
Explanation:

Sally's mass on Moon is: C. 50 kg
Mass is a measure of the amount of matter that an object or a body is typically made up of. The standard unit of measurement for the mass of an object is kilograms (kg).
Regardless of the location of a person, an object at any given time, mass (amount of matter that they're made up of) is always the same i.e constant.
This ultimately implies that, whether you're on the Moon, space, planet Earth or any other place; your mass would always remain the same or constant.
In this scenario, Sally's mass on Earth is 50 kg. Thus, we can deduce that her mass on Moon would be 50 kg.
