Answer 1

Answer:

Amoeba (plural = amoebae) is a well known genus of unicellular organism, a protist. One of its most common species, the Amoeba Proteus, is about 0.2 to 0.3 mm large. The amoeba was first discovered by August Von Rosenhof in 1757.[1] It is a genus of protozoa that moves with false feet, called pseudopodia.

The wave take 0.12 to reach the satellite. Calculate the height of the orbit of the communications satellite

Answers

Answer:

x = 3.6 10⁷ m

Explanation:

The speed of an electromagnetic wave is constant, in a vacuum its value is    c = 3 10⁸ m / s, this speed decreases when entering a material medium,

         v = c / n

where n is the refractive index, but in this case the refractive index of air is n = 1.00002. The refractive index of a vacuum is n = 1, so we can assume that the change in velocity is negligible.

For the calculation we can use the relations of the uniform motion

        v = x / t

        x = v t

let's calculate

        x = 3 10⁸ 0.12

        x = 3.6 10⁷ m

what is an electron shell

Answers

Answer:

In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atom's nucleus. The closest shell to the nucleus is called the "1 shell", followed by the "2 shell", then the "3 shell", and so on farther and farther from the nucleus.

Explanation:

Answer:

An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n

A rectangular block of copper metal weighs 1896 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, what is the density of copper? (hint: find the volume of a block first)

Answers

Answer:

8.9 g/cm^3

Explanation:

density = mass/volume

volume = length * width * height

volume = (8.4 cm)(5.5 cm)(4.6 cm)

volume = 212.52 cm^3

mass = 1896 g

density = (1896 g)/(212.52 cm^3)

density = 8.9 g/cm^3

The brightest, hottest, and most massive stars are the brilliant blue stars designated as spectral class O. If a class O star with a mass of 3.38 ´ 1031 kg has a kinetic energy of 1.30 ´ 1042 J, what is its speed?

Answers

Answer:

2.77 * 10^5 m/s

Explanation:

Let us recall that kinetic energy is given by 1/2 mv^2

Where;

m = mass of the body

v = velocity of the body

In this case,

m = 3.38 * 10^31 kg

KE= 1.30 * 10^42 J

KE = 1/2 mv^2

v = √2KE/m

v = √2 * 1.30 * 10^42/3.38 * 10^31

v = √7.69 * 10^10

v = 2.77 * 10^5 m/s

a. The needle is aligned with the coil.
b. The needle is aligned with the electrical field from the battery.
c. The needle is aligned with the magnetic field from the coil.
d. None of the above

Answers

Answer: C. The needle is aligned with the magnetic field from the coil.

The best explanation for the position of the compass needle in the investigation is "The needle is aligned with the magnetic field from the coil." The correct option is C.

What is a magnetic field?

A magnetic field is a region in space where a magnetic force can be detected. It is created by moving charges, such as electrons in a current or the motion of the Earth's molten core. The strength and direction of the magnetic field depend on the properties of the magnetic source and can be visualized using magnetic field lines. The magnetic field plays a fundamental role in electromagnetism and has important practical applications in a wide range of devices, from electric motors and generators to MRI machines and particle accelerators.

Here in the Question,

The strength of an electromagnet depends on the strength of the magnetic field produced by the current flowing through the coil. As the current flows through the coil, it generates a magnetic field around it, which causes the compass needle to align with the field lines. The direction of the magnetic field around the coil depends on the direction of the current flowing through it, and the compass needle aligns itself with the magnetic field lines produced by the coil.

Option (a) The needle is aligned with the coil is not a correct explanation because the compass needle is not aligned with the physical coil itself but with the magnetic field generated by the coil.

Option (b) The needle is aligned with the electrical field from the battery is not a correct explanation because the electrical field produced by the battery does not affect the position of the compass needle. The electrical field is used to create a current in the coil, which produces a magnetic field that the compass needle aligns with.

Option (d) None of the above is not a correct explanation because the compass needle is indeed aligned with the magnetic field produced by the coil.

Therefore, the best explanation for the position of the compass needle is that it is aligned with the magnetic field from the coil.

-Try one new workout every month. Keeping the same exact routine when it comes to your fitness is never a good thing.

-More water
With any diet, the most important thing to remember is to stay hydrated. Drinking water will support your body with digestion, transporting nutrients to your bones and muscles, and even improving cognitive function.
Ideally, you want to drink about half your body weight in ounces per day, i.e. if you weight 150 pounds, you should drink 75 ounces of water a day.

-Stretching
The benefits are vast and the repercussions of failing to stretch can be dramatic.
Do yourself a favor and always stretch before and after a workout. This will promote a healthy cool down, improve flexibility, and reduce next day aches. Failure to stretch can lead to injures and muscle damage.

-Body Fat
This may seem like an obvious one, but it is one of the most important steps to a healthier you. Reducing your body fat has a lot of benefits such as:

Improved joints and tendons
Lowered risk of diabetes
Reduced risk of heart disease
Reduced inflammation
Better performance and endurance
Improved appearance and confidence
Better hormonal profiles in your body
Remember, it is not a race to see how quickly you can decrease your body fat. Healthy weight loss is around 1-2 pounds a week for your fitness goals.[2]

Crash dieting or pushing yourself too much in the gym can lead to you achieving an unrealistic target, and you may find yourself gaining all the weight you have lost.

a chef is testing out a new iron cookware. He knows that iron specific heat of 445 j/kg Celsius. he heats a 2kg iron pan on a stove for 5 minutes and finds that the temperature of the iron skillet has increased by 150 degrees Celsius. calculate the amount of heat energy absorbed by the pan.

Answers

Answer:

[tex]\boxed {\boxed {\sf 133,500 \ Joules}}[/tex]

Explanation:

Since we are given the specific heat, mass, and change in temperature, we should use this formula for heat energy.

[tex]q=mc \Delta T[/tex]

The mass is 2 kilograms. Iron's specific heat is 445 Joules per kilogram degree Celsius. The temperature increases by 150 degrees Celsius.

[tex]m= 2 \ kg \\c= 445 \ J/kg \textdegree C\\\Delta T= 150 \textdegree C[/tex]

Substitute the values into the formula.

[tex]q= (2 \ kg)( 445 \ J/kg \textdegree C)(150 \textdegree C)[/tex]

Multiply the first two numbers. The kilograms will cancel.

[tex]q= 890 \ J/\textdegree C (150 \textdegree C)[/tex]

Multiply again. This time the degrees Celsius cancel.

[tex]q= 133, 500 \ J[/tex]

The pan absorbs 133,500 Joules of heat energy.
