Answer:A
Explanation:I believe the correct answer would be they join north pole to south pole. The direction of these lines always goes from the direction of north to south pole. These lines forms loops in order to favor the way which requires or has less resistance.
They point away from the north pole and towards the south pole, is the statement correctly describing magnetic field lines around a bar magnet.
What is a bar magnet?A bar magnet is a rectangular section of an item that has permanent magnetic qualities and is made of iron, steel, or any other ferromagnetic material or ferromagnetic composite.
It has two poles, one north, and one south, and when hanging freely, the magnet aligns itself such that the north pole faces the earth's magnetic north pole.
They point away from the north pole and towards the south pole, the statement correctly describes magnetic field lines around a bar magnet.
Hence statement B correctly describes magnetic field lines around a bar magnet.

A 6.00 volt battery is in a circuit with two resistors, A and B, connected in parallel. If the current flowing
out of the battery is 90.0 mA, what is the value in ohms of B if A is 100 ?
Answers
Answer: [tex]200\Omega[/tex]
Explanation:
Given
The battery used is 6V in magnitude
The current flow is 90 mA
If the resistance of A is [tex]100\Omega[/tex]
Net resistance of the circuit is
[tex]R_{net}=\dfrac{V}{I}\\\\\Rightarrow R_{net}=\dfrac{6}{90\times 10^{-3}}\\\\\Rightarrow R_{net}=\dfrac{200}{3}\Omega[/tex]
If A and B are in parallel then their net resistance must be [tex]\frac{200}{3}[/tex]
[tex]\dfrac{1}{\frac{200}{3}}=\dfrac{1}{100}+\dfrac{1}{R_b}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3}{200}-\dfrac{1}{100}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3-2}{200}\\\\\Rightarrow R_b=200\Omega[/tex]
What type of energy do not harm our environment?
Answers
Answer:
Explanation: Renewable energy is energy that has been derived from earth's natural resources that are not finite or exhaustible, such as wind and sunlight. Renewable energy is an alternative to the traditional energy that relies on fossil fuels, and it tends to be much less harmful to the environment.
what effect does the earth's surface have on solar radiation?
A. The ground absorbs half the solar radiation and stored it as infrared radiation for centuries
B. Half of the solar radiation is absorbed and converted to infrared (heat)
C. Nearly all solar radiation is reflected back into space by the ground
Answers
Answer:
B.
Explanation:
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. In total approximately 70% of incoming radiation is absorbed by the atmosphere and the Earth’s surface while around 30% is reflected back to space and does not heat the surface. The Earth radiates energy at wavelengths much longer than the Sun because it is colder. Part of this longwave radiation is absorbed by greenhouse gases which then radiate energy into all directions, including downwards and thereby trapping heat in the atmosphere.
Hope this helps, sorry if it is incorrect. Have a great day/night!

Higher amplitudes sound will have a _____________________ sound while lower amplitude will have a __________________________ sound. 10. The speed of sound is dependent on density and temperature of the medium being used so that higher density or temperature will yield a (higher / lower) speed (Kinetic Molecular Theory). 11. Give an example of any resonance heard: 12. Give an example of any echo heard. 13. Give an example of any evidence that sound is energy traveling in waves.
Answers
Answer:
9) HIGHER AND LOWER INTESITY, 10) speed of sound must decrease.
11) guitar the strings, flute, 12) In the mountains, 13) sound of a low frequency horn (sub-wofeer)
Explanation:
In this exercise we are asked to complete the sentences.
9) the intensity of the sound is the square of the amplitude, the missing words are
HIGHER INTESITY
LOWER INTENSITY
10) the speed of sound is
v = [tex]\sqrt{\frac{B}{\rho} }[/tex]
and it is also related to temperature
v = [tex]v_o \sqrt{1+ \frac{T}{273} }[/tex]
We must be careful since the compressibility modulus (B) changes significantly between the solid, liquid and gaseous states, if we are in the same medium, the speed of sound decreases with increasing density. For a higher density the speed of sound decreases
Also the speed of sound increases with temperature, but its effect is less,
Therefore, by having these two effects in the opposite direction, the change in density is more important, so the speed of sound must decrease.
.
11) when you listen to a guitar the strings resonate with the instrument body
on the flute has a resonance between the blown air and the flute tube
12) When you are in front of a tall object, the sound is reflected and the echo is heard.
In the mountains, in the squares where there is a large object that reflects in sound
13) when we hear the sound of a low frequency horn (sub-wofeer) we feel the vibration of the air, this is an effect of the pressure energy of the sound on our chest

Answers
Answer:
1. Solar wind: a stream of plasma.
2. Coronal mass ejection: includes prominences and solar flares.
3. Gamma ray photon: energy released during nuclear fusion.
Explanation:
1. Solar wind: a stream of plasma i.e charged particles such as ions, protons, alpha, and electrons that continuously escape at high speed from the Sun because of the very hot plasma contained in the solar corona.
2. Coronal mass ejection: includes prominences and solar flares that flow outward into interplanetary space. Thus, it's a release of solar wind plasma and magnetic field from the outer atmosphere or corona of the sun.
Additionally, a solar prominence is also known as filament and it can be defined as a large, bright, dense cloud of luminous ionized gas such as hydrogen, sodium calcium, etc., that erupts (extends) from the surface of the sun. It can linger in the corona for a very long time, reaching hundreds of thousands of kilometers into the sun's atmosphere (space).
3. Gamma ray photon: energy released during nuclear fusion of radioactive isotopes such as cobalt-60 or cesium-137. It has the shortest wavelength and highest energy in the electromagnetic radiation spectrum.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.

Applying
V = kq/r......................... Equation 1
Where V = Electric potential, q = charge, r = distance, k = Coulomb's constant.
make r the subject of the equation
r = kq/V................... Equation 2
From the question,
Given: q = 1.00×10⁻⁵ C, V = 10000 V
Constant: k = 9.0×10⁹ N⋅m²/C²
Substitute these values into equation 2
r = (9.0×10⁹×1.00×10⁻⁵)/10000

A hot, just-minted copper coin is placed in 101 g of water to cool. The
water temperature changes by 8.39°C and the temperature of the coin
changes by 68.0°C. What is the mass of the coin? Disregard any energy
transfer to the water's surroundings.
Answers
Answer:the specific heat is the measure of how much heat per unfit mass required to raise the temperature by 1 degrees Celsius.the formula is given as Q= cm T where
Q= the amount of heat added
C= specific heat of a substance
T= change in temperature in degrees Celsius
Q=(4186 j/kg degrees Celsius (.109 kg) (8.93- degrees Celsius)=4974.53J
Explanation:
The mass of the copper coin placed in 101g of water is 135.3g.
COLORIMETER:The mass of the copper coin can be calculated using the following expression:
Since; Q = mc∆T
Where;
Q = heat absorbed or releasedm = mass of substancec = specific heat capacity of substance∆T = change in temperaturemc∆T (water) = mc∆T (copper)
According to this question;
COPPER METAL:
m = ?c = 0.385 J/g°C∆T = 68°CWATER:
m = 101gc = 4.18 J/g°C∆T = 8.39°C101 × 4.18 × 8.39 = (0.385 × m × 68)
3542.09 = 26.18m
m = 3542.09 ÷ 26.18
m = 135.3g
Therefore, the mass of the copper coin placed in 101g of water is 135.3g.
