Answer:

Nanomagnetic chips.

Explanation:

In a computer, the hard disk drive chips are magnetic.

A non-volatile data storage device is a computer hard disk drive (HDD). Non-volatile storage devices are those that retain data even after being turned off. HDDs are merely one form of storage device, yet they are required by all computers.

Desktop computers, mobile phones, consumer gadgets, and enterprise storage arrays in data centers are frequently equipped with HDDs. They can use magnetic disks to store operating systems, applications, and other things.

Answer:

Newtons.

Explanation:

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex]

Where;

F represents force measured in Newton.

m represents the mass of an object measured in kilograms.

a represents acceleration measured in meter per seconds square.

Newtons is a measurement we use to determine the amount of force used to move an object by a simple machine. It is the International System of Units (SI) used to measure force and has a symbol of N.

Basically, it was named after Sir Isaac Newton based on his fundamental works in the field of mechanics (motions).

Answer:

hence the y - component of the velocity is 50m/s

Answer:

When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). ... When the pressure exerted on a substance increases, it can cause the substance to condense.

Answer:

The velocity of Mosquito with respect to earth will be 0.302m/s

Explanation:

V(ma) = 1.10 m/s, east  Velocity of mosquito with respect to air

V(ae) = 1.4 m/s at 35°  Velocity of air with respect to Earth in west of south direction.

Velocity of Mosquito with respect to earth will be  

V(me) = V(ma) + V(ae)

We need to find the mosquito’s speed with respect to Earth in the x direction.

V(x, me) = V(x, ma) + V(x, ae) = V(ma) + V(ae)(cos theta(ae) )

Angle (ae) = –90.0° − 35°=−125°

V(x, me) = 1.10 + (1.4)Cos(-125)

             = 1.10 + 1.4(-0.57)

             = 1.10 -0.798

              = 0.302

So the velocity of Mosquito with respect to earth will be 0.302m/s

low frequencies

Explanation:

The type of sonar that causes loud noises in the water is known as active sonar.

Active sonar is a system that emits sound waves into the water and listens for their reflections to detect objects and measure distances. It works by sending out a pulse of sound, which travels through the water and reflects off objects such as submarines, ships, or marine life.

The reflected sound, or echo, is then received by the sonar system's hydrophone, allowing it to analyze the data and provide information about the surrounding environment.

While active sonar is effective for detecting objects and underwater features, it can also produce loud noises that may have various effects on marine life.

The loud sound pulses can potentially disturb or harm marine animals, particularly marine mammals like whales and dolphins, which rely heavily on sound for communication and navigation. The use of active sonar has been a topic of environmental concern, and efforts are made to minimize its impact on marine ecosystems through regulations and responsible use.

Hence, The type of sonar that causes loud noises in the water is known as active sonar.

yes i think that inner planets should be explored because if we ever find new life or are able to live there then i think its worth takeing a risk.

Explanation:

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Explanation:

I majored in Physics

When a snowball thrown at an ice cream truck at Valley Forge in January sticks to the side, the mechanical energy was  changed into thermal energy.

Energy cannot be created or destroyed, according to the rule of conservation of energy. However, it is capable of change from one form to another. An isolated system's total energy is constant regardless of the types of energy present.

The law of energy conservation is adhered to by all energy forms. The law of conservation of energy essentially says that all energy is conserved in closed systems, or systems that are isolated from their surroundings.

Answer: So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. ... That means that longer wavelengths have a lower frequency. Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!

If the wavelength of a wave is short. It is true that the wave will have a lower frequency. A longer wavelength denotes a lower frequency.

A wave is a phenomenon that flows across a material medium without leaving any lasting mark.

Frequency is defined as the number of cycles per second. The time to make one complete cycle is the frequency and the distance between successive crests of a wave is the wavelength.

Thus, a shorter wavelength of a light wave signifies a greater frequency since one cycle may pass in a shorter amount of time. Longer wavelengths have a lower frequency.

Hence  a longer wavelength denotes a lower frequency, whereas a shorter wavelength denotes a higher frequency.

Answer:

E₀ = 5.97 10⁸ N / C

Explanation:

Coulomb's law in a material medium is written

       [tex]F = \frac{1}{4\pi \epsilon } \frac{q_{1} q_{2} }{r^{2} }[/tex]

ε is the electrical permittivity of the material

Electric field and force are related        

          F = q E

in dielectric materials such as mica there is an electric field inside the material that decreases the external field

           E = E₀ /ε

where ε is the electrical permittivity of the material; in general it is tabulated in the form

           [tex]\epsilon _{r} =\frac{\epsilon}{\epsilon_{o}}[/tex]

          [tex]\epsilon = \epsilon_{r} \ \epsilon_{o}[/tex]

we substitute

          F = q E₀ /  \epsilon_{r}  \epsilon_{o}

         [tex]E_{o} = \frac{F \ \epsilon_{r} \ \epsilon_{o} }{q}[/tex]

for the case of mica it is equal to er = 5.4 and suppose a test charge equal to the charge of the electron

we calculate

          E₀ = 2  5.4  8.85 10⁻¹² / 1.6 10⁻¹⁹

          E₀ = 59.74 10⁷

          E₀ = 5.97 10⁸ N / C

Explanation:

Option C is the correct answer

Infrared radiation from the Sun is trapped by greenhouse gases and heats the atmosphere, by this phenomenon of heat absorption the greenhouse gases warm the atmosphere,therefore the correct answer is option C.

The propagation of electromagnetic waves, which are generated from both natural and artificial sources, results in the energy radiation known as electromagnetic radiation.

This radiation does not need any kind of medium to propagate. The electromagnetic wave has components of light as well as heat in them.

By absorbing heat through the process of heat assimilation, greenhouse gases warm the atmosphere by trapping infrared light from the Sun.

Thus, the correct answer is option C.
