Which of the following has 5 significant digits?
O 0.00030
O 50,000
O 100.0300
O 500.00
Answer:
50,000
Explanation:
when we say significant digits we mean the numbers that matter when stating the value of the number.
0.00030 can be written as 0.0003 without affecting it's value, the last zero is not significant.
50,000 all of the numbers here are significant to its value if we take away a zero it becomes 5,000 which is not equal to 50,000. so every digit here is significant
100.0300 can be written as 100.03 without loosing any value
500.00 can be written as 500 without loosing any value. ( think of this as $500.00, this also equals $500)
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
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!

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 ?
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]

Se tienen 500g de alcohol etílico a una temperatura de -40 °C ¿Cuánto calor se necesita para transformarlo a vapor a una temperatura de 150ºC?
The question is: You have 500g of ethyl alcohol at a temperature of -40 ° C. How much heat is needed to transform it into steam at a temperature of 150ºC?
Answer: 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of [tex]-40^{o}C[/tex] to [tex]150^{o}C[/tex].
Explanation:
Given: Mass = 500 g
Initial temperature = [tex]-40^{o}C[/tex]
Final temperature = [tex]150^{o}C[/tex]
The standard value of specific heat of ethyl alcohol is [tex]2.46 J/g ^{o}C[/tex].
Formula used to calculate the heat energy is as follows.
[tex]q = m \times C \times (T_{2} - T_{1})[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat
[tex]T_{1}[/tex] = initial temperature
[tex]T_{2}[/tex] = final temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times (T_{2} - T_{1})\\= 500 g \times 2.46 J/g^{o}C \times [150 - (-40)]^{o}C\\= 233700 J[/tex]
Thus, we can conclude that 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of [tex]-40^{o}C[/tex] to [tex]150^{o}C[/tex].

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.
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

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.

If Europium (Eu) undergoes proton decay and loses 3 protons, which element will it become?
Answer:
Neodymium (Nd)
Explanation:
An element is made up of atom, which contains three subatomic particles namely; proton, electron, and neutron. In a neutral atom, the number of protons determines the atomic number of that element and the atomic number of an element is the identity of that element in the periodic table.
Hence, a change in the proton number of an element means a change in the atomic number and ultimately a change of that element. In this question, Europium (Eu) element with atomic number, 63, loses three protons. This means that that atom now has 60 protons, which denotes the atomic number of another element called Neodymium (Nd).
Therefore, Europium (Eu) element has become Neodymium (Nd) due to loss of protons.
