Answer:  

Evaporation rate is the dependent variable in Pedro's experiment

Explanation:

it is the variable that is being measured and is expected to change in response to changes in humidity. The independent variable is humidity, which is being manipulated by placing one beaker near a humidifier and the other in a dry area. Temperature and volume of water are not being directly manipulated in this experiment and are therefore not the dependent variable.

Answer:

A. they emit more blue light than stars like the Sun

Answer:

Myth: A dead organism is the same as a nonliving thing in science. ... Things that are dead once did have the characteristics of life, but when they die, they lose some of the characteristics. That is why dead and non-living are NOT the same thing.

Answer:

Non-living thing is never alive.

Dead thing was once alive.

Living things can breathe, grow, reproduce, detect and respond to the changes in the environment, excrete, use the energy from the environment. E.g., Animals

Non-living things don't exhibit these characteristics. E.g., Soil, air

Let's take an example of living things, say lion. When a lion dies, we never say,”Lion has become a non living thing now”. But we say,” Lion is dead”. Death can only happen to living things.

Lion is dead now. But it was once alive.

But soil is never alive. Never dead too!

Hope this helps!

Have a great day!

Explanation:

The wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

The wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.

Why does the wind move?

he wind blows because of differences in air pressure. ... Instead, the wind blows anti-clockwise around the low pressure area in the Northern Hemisphere and clockwise in the Southern Hemisphere. This is the effect of the earth's rotation, which produces a force, called Coriolis, that deflects the wind from its path.

Why does air move to one place or another?

Air moves because the sun generates heat on the earth, this causes hot air, hot air rises creating wind, the air which is made up of 02 C02 and many other gases is carried by wind. air moves from place to place due to the different temperature and pressure conditions on the earth

Answer:

1.) Wavelength

2.) Number of fringes

Explanation:

1.) If we split a laser beam by using a diffraction grating slide, then we can

verify the wavelength by applying the formula λ​ = ds/l.

2) If we split light into its individual wavelengths using a diffraction grating,

then we can determine the number of fringes by multiplying the spacing of the gradient lines (d) times the distance to the central maxima of the color band (s) divided by the length distance from the grating slide to the screen (l).​

Answer:

Drag friction.

Explanation:

If you have a solid object, go through air, it experiences drag because the air molecules push back a tiny bit. This drag is enhanced because in water, the molecules are more resistant than air, that's why if you try to run in knee deep water, you experience much more drag than when you are running with your legs out of the water.

Explanation:

Try to remember that sleep deprivation or the lack of sleep, messes with the amygdala in the brain - this is the part of the brain that controls some of our emotions.  If you mess with the amygdala then it messes with you - it will cause you to be more fight than flight - it can make you hypersensitive to stuff that you normally could use your coping skills to conquer!

Explanation:

Hope this helps!

Answer:

Electrical forces result from mutual interactions between two charges. ... The direction of each of these three forces can be determined by applying the basic rules of charge interaction: oppositely charged objects attract and like-charged objects repel

Explanation:

Explanation:

We have,

Number of turns in a coil is 41

Dimensions of a rectangular coil is 5 cm by 10 cm

Initial magnetic field is 0 and new field is 0.52 T. The magnetic field is directed perpendicular to the plane of the coil.

It is required to find the magnitude of the average emf that is induced in the coil if the displacement occurs in 0.330 s. According to Faraday's law,

[tex]E=\dfrac{-d\phi}{dt}[/tex]

[tex]\phi[/tex] = magnetic flux

[tex]E=\dfrac{-d(NBA)}{dt}\\\\E=NA\dfrac{-(B_f-B_i)}{dt}\\\\E=41\times 0.005\times \dfrac{(0.52)}{0.33}\\E=0.32\ V[/tex]

So, the magnitude of induced emf is 0.32 V.

Answer: C.

The sum of all the acceleration vectors

Explanation: The word resultant means the sum of two or more vectors.

Since acceleration is a vector quantity,

The resultant acceleration will be the sum of all the acceleration vectors. Where there are two or more acceleration to be considered on an object in a system.

In order for you to lift abook off the ground the energy involved is mechanical energy which involves potential energy to kinetic energy transformation

Answer:

Change in velocity = 0.219 × 10⁸ m/s (Approx)

Explanation:

Given:

Ray moving through glass (n1) = 1.51

Ray moving through (n2) = 1.36

Find:

Change in velocity.

Computation:

Speed of light = 3 × 10⁸

Change in velocity = [(c/n2) - (c/n1)]

Change in velocity = [(c/n1) - (c/n1)]

Change in velocity = 3 × 10⁸[(1/1.36) - (1/1.51)]

Change in velocity = 3 × 10⁸[0.7352-0.6622]

Change in velocity = 3 × 10⁸[0.073]

Change in velocity = 0.219 × 10⁸ m/s (Approx)

Answer: The term magnetism comes from the region of Magnesia, a city in Western Turkey, where Greeks found lodestones, which attracted iron pieces across the space.   It is also observed that, magnets attract as well as repel.  We can explain this dual nature of magnetic force by proposing that each magnet has two poles, north pole (N) and south pole (S).  You will observe two things during the activities:

1)      When two magnets are brought near each other, like poles repel; opposite poles attract.

2)      When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.

Answer:

D. The resistance increases.

Explanation:

Resistance of a wire is R = ρL/A, where ρ is the resistivity of the wire, L is the length, and A is the cross sectional area.

As L increases, R increases.

Answer:

At Convergent Boundaries:

Subduction

Island arcs

Volcanic mountains

At Divergent Boundaries:

Mid-ocean ridges

Rift valleys

Plates pulling apart

Magma breaks through crust

Magma flows from cracks

Explanation:

A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

Divergent boundaries occur in the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.

Answer:

39.) Current = 1.5 A

40.) B

Explanation:

Given that three 12 Ohms resistors are connected in parallel.

The equivalent resistance R will be

1/R = 1/R1 + 1/R2 + 1/R3

Substitute the values into the formula

1/R = 1/12 + 1/12 + 1/12

1/R = 3/12

Find the reciprocal of both sides

R = 12/3

R = 4 Ohms

From Ohm's law,

V = IR

Where V = 6v

Substitute V and the R into the formula and make current I the subject of formula

6 = I × 4

I = 6/4

I = 1.5 A

Therefore, the resulting current is 1.5 Ampere.

40.) If the devices and outlets in each circuit in a household are wired in parallel, The main reason for this is

Plugging in more devices decreases the total resistance on the circuit.

Because, the sum of resistance of resistors in parallel is less than the least resistance of a resistor is the circuit. Also, they will all share the same amount of voltage because there is no voltage drop.

Answer:

The answer is D.

Explanation:

An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base.
