In each of the following pairs, circle the form of radiation with the LONGER WAVELENGTH:

A. red light or blue light

B. microwaves or radiowaves

C. infrared radiation or red light

D. gamma rays or UV rays​

Answer:

Equation:

Q = m•C•ΔT

Answer:

Sediment

Explanation:

Explanation:

Area = Length × Breadth

A = 4 × 6

A = 24m square/ 24m sq.

Force = Pressure × Area

Force = 60,000 N/ 60,000 Newton

Pressure = Force/ Area

P = 60,000/24

P = 2500 Pa

Human Movement is important because it most commonly used to insure optimal athletic ability. It can also be used to identify the cause of most common sports injuries and movement-related problems. The name for this type of study is called Kinesiology. This is a very necessary part of students understanding dance, sports, and physical well-being. Studying Kinesiology results in better physical performance, as well as many cardiovascular improvements. Kinesiology is used to answer many still unknown question about human movement.

Answer:

The lower the temperature, the lower the pressure inside of the sphere. If the exact values were plotted out, a linear relationship would be apparent. Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.

D: the thermal energy is moving from the ice cube into the water causing the temperature of the water to decrease.​



Answer:

The correct option is D) Humidity levels will rise

Explanation:

A rise in humidity means that it is most likely there is going to be a rain.

When blue semi-circle lines with triangles approach red semi-circle lines it is a situation where cold front is approaching a warm front.

The resultant effect is that the warm and cold air both come to a standstill. This will most likely trigger cloud and fog and may even lead to rain.

Answer:

water vapor

Explanation:

because gas molecules moves the fastest

Answer:

water vapor

Explanation:

Liquid water molecules have less freedom to move around. While molecules of water vapour have more freedom to move around as there is larger space between the molecules. Hence, the kinetic energy of water molecules is more as compared to the kinetic energy of liquid water

Answer:

c. no reaction happens

Explanation:

Let me take your mind back to the idea of electrode potentials of metals. Remember that the more negative the electrode potential of a metal, the more reducing the metal is. Metals with more negative electrode potentials displace metals with less negative electrode potentials from their aqueous solutions.

The electrode potential of nickel is -0.25 V while that of copper is +0.34 V. Hence, copper is lower than nickel in the activity series and can not displace it from aqueous solution.

This implies that, if a piece of copper metal is placed in a solution that contains nickel(II) ions, no reaction happens .

Answer:

opposite

Explanation:

Newtons law explains that for every action force there is an equal and opposite reaction.

Answer:

Based on their groups

Explanation:

Answer:

They are arranged vertically depending on how many valence electrons they have, if they have the same amount, they will have the same chemical family in each column.

Answer:

Here is an example of anchoring Bias

If I were to ask you where you think Apple’s stock will be in three months, how would you approach it? Many people would first say, “Okay, where’s the stock today?” Then, based on where the stock is today, they will make an assumption about where it’s going to be in three months. That’s a form of anchoring bias. We’re starting with a price today, and we’re building our sense of value based on that anchor.

Anchoring bias occurs when people rely too much on pre-existing information or the first information they find when making decisions. For example, if you first see a T-shirt that costs $1,200 – then see a second one that costs $100 – you're prone to see the second shirt as cheap.

Anchoring or focalism is a term used in psychology to describe the common human tendency to rely too heavily, or "anchor," on one trait or piece of information when making decisions.

Mass percentage does not have any unit as numerator and denominator contains the same unit. The percentage of sulfuric acid in solid sample is 38.07%.

Mass percentage represents the the percentage of each element that is making a particular compound.

Mathematically,

Percentage of mass = (component’s mass ÷ total mass) x 100%

[tex]\rm 2 NaOH aq + H _{2} SO _{4} aq → Na _{2}SO _{4}aq + 2 H _{2} O[/tex]

Volume of NaOH solution = 32.22 mL = 0.03222 L

Concentration or molarity of the NaOH solution = 0.2012 M

Moles of NaOH : 0.03222×0.2012=0.006444mol

2 moles of sodium hydroxide reacts with 1 mole of sulfuric acid.

0.006444mol of sodium hydroxide reacts with =0.006444÷2=0.003222mol of sulfuric acid.

Mass of sulfuric acid neutralized = 0.003222 moles × 98.08 g/mol =0.31601376g

Percentage of sulfuric acid in solid sample= (0.31601376g÷0.8390g)×100=38.07%

Thus the percentage of sulfuric acid in solid sample is 38.07%.

Answer:sodium

Speed in excess of 100 km/h, which is 208.8 km / h

Linear motion consists of 2: constant velocity motion with constant velocity and uniformly accelerated motion with constant acceleration  

• An equation of uniformly accelerated motion  

[tex]\large {\boxed {\bold {x=xo+vo.t+\frac {1} {2} at ^ 2}}}[/tex]

vt = vo + at  

vt² = vo² + 2a (x-xo)  

x = distance on t  

vo / vi = initial speed  

vt / vf = speed on t / final speed  

a = acceleration  

I think it's not chemistry but physics

Δx = 290 m

vf = 0⇒stop

Δt = 10 s

We use the formula in the question

[tex]\tt \Delta x=\dfrac{1}{2}(vf+vi)\Delta t\\\\290=\dfrac{1}{2}(0+vi).10\\\\vi=58~m/s=\boxed{\bold{208.8~km/h}}[/tex]

Answer:

density = 2g/cm³

Explanation:

density = mass/volume

mass = 20g

volume = 10cm³

density = 20g/10cm³

density = 2g/cm³

Answer:

The length of the cuboid =x=2m, breadth =2x=4m, height =3x=6m

Explanation:

Let the length of the cuboid =x, breadth =2x, height =3x

Total surface area of a cuboid =2(l×b+b×h+l×h)

Given, total surface area of the cuboid =88m^2

2( x*2x + 2x*3x + x*3x )=88m

22x^2 =88

x=2

Hence, the length of the cuboid =x=2m, breadth =2x=4m, height =3x=6m
