Answer:
(4) The physical and chemical properties of these minerals determine how humans use them.
Explanation:
All the materials and the metals found on earth shows certain characteristics naturally or in their physical state. These physical characteristics can be their look, their structure, their color, strength, melting point, boiling point, density, etc.
And chemical properties of the metals are defined as those characteristics or features of the metals that it exhibits when these metals reacts chemically.
The physical properties as well as the chemical properties distinguishes each metal from each other. These properties determines how people use these metals in their life.
Which is not a way in which life is dependent on photosynthesis?
A.) Organisms breathe in the oxygen
B.) Its sugar is used as a food
C.) Helps cure disease
D.) Helps reduce global warming
Answer:
The answer is A
Explanation:
I have had this question before
hope this helps!! <3
The one that is not a way in which life is dependent on photosynthesis is that helping in cure of diseases. The correct option is C.
What is photosynthesis?Photosynthesis is a technique that plants as well as other lifeforms use to transform light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
Photosynthesis' primary function is to convert solar energy into chemical energy and then store that chemical energy for later use. This process powers the majority of the planet's living systems.
Photosynthesis is essential to all living things because it is the primary source of oxygen in the atmosphere.
Without photosynthetic activity, the carbon cycle would not have been possible, oxygen-requiring life would perish, and plants would perish.
Due to photosynthesis, the organisms breathe in the oxygen, sugar is used as a food, and also helps to lower down global warming.
Thus, the correct option is C.

If you were to throw one show with a force of 20 Newtons and the other with a force of 10 Newtons, which would accelerate more? Why?
Answer:
The show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.
Explanation:
From Newton's second law of motion, acceleration is the ratio of applied to mass of the object.
[tex]acceleration = \frac{Force}{mass}[/tex]
Acceleration is directly proportional to an applied force. At a constant mass, acceleration increases with an increase in the applied force.
Therefore, the show with 20 N force will accelerate more than the show with 10 N force, because 20 N force is greater than 10 N force.

1.-Una fuerza horizontal de 40 N es apenas suficiente para poner en marcha un trineo de 600 N sobre nieve compacta. Después de empezar el movimiento se requieren tan solo 10 N para mantener el trineo a rapidez constante. Halle los coeficientes de fricción estática y cinética
Answer:
Los coeficientes de fricción estática y cinética son [tex]\frac{1}{15}[/tex] y [tex]\frac{1}{60}[/tex], respectivamente.
Explanation:
Por la Primera Ley de Newton, sabemos que la fuerza externa debe tener igual magnitud y dirección contraria a la fuerza de reacción (fricción). Puesto que el trineo se mueve sobre una superficie horizontal, la magnitud de la fuerza normal es la del peso ([tex]W[/tex]), en newtons. El coeficiente de fricción estática ([tex]\mu_{s}[/tex]), sin unidad, es la razón de la fuerza de fricción justo antes del movimiento inminente ([tex]F[/tex]), en newtons, a la fuerza normal ([tex]N[/tex]), en newtons:
[tex]\mu_{s} = \frac{F}{W}[/tex] (1)
Si sabemos que [tex]F = 40\,N[/tex] y [tex]W = 600\,N[/tex], entonces el coeficiente de fricción estática es:
[tex]\mu_{s} = \frac{F}{W}[/tex]
[tex]\mu_{s} = \frac{40\,N}{600\,N}[/tex]
[tex]\mu_{s} = \frac{1}{15}[/tex]
El coeficiente de fricción cinética ([tex]\mu_{k}[/tex]), sin unidad, es la razón de la fuerza de fricción experimentada por el trineo en movimiento ([tex]F[/tex]), en newtons, a la fuerza normal:
[tex]\mu_{k} = \frac{F}{W}[/tex] (2)
Si sabemos que [tex]F = 10\,N[/tex] y [tex]W = 600\,N[/tex], entonces el coeficiente de fricción cinética es:
[tex]\mu_{k} = \frac{F}{W}[/tex]
[tex]\mu_{k} = \frac{10\,N}{600\,N}[/tex]
[tex]\mu_{k} = \frac{1}{60}[/tex]
Los coeficientes de fricción estática y cinética son [tex]\frac{1}{15}[/tex] y [tex]\frac{1}{60}[/tex], respectivamente.

If the wavelength of a wave stays the same and the speed doubles, what happens to the frequency of the wave?
Explanation:
velocity = wavelength × frequency => v= f1 × λ => f1 = v/ λ
λ = stays the same
v = doubles
2v = f2 × λ
2v/λ = f2
now ,
f2/f1= 2vλ/ vλ = 2
f2 = 2f1
therefore frequency is doubled

What is the mass number, symbol, and charge of an ion that contains 35 protons, 45 neutrons and 36 electrons?
Bromine contains 35 protons, 36 electrons, and 45 neutrons. The mass number of Bromine is 80. The ion charge of bromine is +7. "Br" is the symbol of Bromine.
Discussion about bromine:
Two chemists, Carl Jacob Löwig and Antoine Balard, independently discovered bromine in 1825 and 1826, respectively.
The chemical element bromine has the atomic number 35 and the symbol Br. It is the 3rd halogen, and at room temperature, it is a flammable red-brown liquid that easily evaporates to create a vapor of a similar color. Its characteristics fall in between those of iodine and chlorine.
Due to its high reactivity, elemental bromine does not naturally occur in its free form but rather as crystals minerals halide salts that are colorless and soluble, similar to table salt. Although the bromide ion (Br) is relatively uncommon in the Earth's mantle, its great solubility has led to its buildup in the seas.

Answer:
So the conclusion is that in presence of air net force acting downward reduces for feather and hence falls slower than coin. But in absence of air resistance, net downward force is just equal to force due to gravity which is same for both coin and feather and hence they fall down at the same rate.

The shortening of a transmitted signal's wavelength and/or an increase in its frequency, which indicates that the object is
moving toward the observer, is called the
Answer: The Doppler effect occurs when a source of a wave is moving relative to an observer (or the observer is moving relative to the source). In this case, the apparent frequency of the sound, as heard/seen by the observer, is shifted with respect to the original frequency of the wave.
More specifically, the relationship between the apparent frequency, f', and the original frequency, f, is given by:
where:
is the velocity of the wave
is the velocity of the observer relative to the source, and it is positive if the observer is moving towards the source, and negative if the observer is moving away from the source
is the velocity of the source relative to the observer, and it is positive if the source is moving away from the observer, and negative if the source is moving towards the observer
The doppler effect occurs in many daily-life situations: for instance, when an ambulance approaches you, you hear an increase in the apparent frequency of the siren due to the Doppler effect. Another example is the movements of distant galaxies from us: when they move away from us, the apparent frequency of the light they emit decreases, so their wavelengths appear to increase towards the red color (red-shift); on the contrary, when they are moving towards us, the apparent frequency seems to increase, so the wavelength seems to decrease towards the blue color (blue-shift).

An asteroid has a mean radius equal to 17 times that of Earth. Using Kepler's 3rd law find its period. T^2=a^3
Answer:
If T^2 = a^3
T1^2 / T2^2 = a1^3 / a2^3
Or T2^2 = T1^2 * ( a2^3 / a1^3)
Given T1 = 1 yr and a2 / a1 = 17
Then T2^2 = 1 * 17^3
or T2 = 70 yrs
Which best describes the type of lens that would help someone with one of these eye conditions? Concave lenses would help someone who is nearsighted because the lenses make objects look smaller and closer. Concave lenses would help someone who is farsighted because the lenses make objects look smaller and closer. Convex lenses would help someone who is nearsighted because the lenses can make objects look smaller and closer. Convex lenses would help someone who is nearsighted because the lenses can make objects look larger and farther away.
Answer:
The answer is "Option a".
Explanation:
The concave lenses are there for narrow-sighted people, convex for the far people. In eyewear, curved lenses are used to rectify visibility. Since in nearsighted individuals the width between the eye lens as well as the retina is larger than should be, these readers can't clearly distinguish distant things.
Answer:
The correct answer is - Concave lenses would help someone who is nearsighted because the lenses make objects look smaller and closer.
Explanation:
Concave lenses are related to the condition of nearsightedness whereas convex lens is related to the farsightedness. Nearsightedness is the condition where a person can see closer objects clearly but the objects at a farther distance can not see properly.
Concave lenses make objects look smaller and closer as it makes the image farther than it is actually. It forms a virtual image as it is a diverging lens.
