Answer:
The answer is 5000 NExplanation:
The force acting on a body can be found by using the formula
force = mass × accelerationFrom the question
mass = 10 kg
acceleration = 500 m/s²
We have
force = 10 × 500
We have the final answer as

Example of Anchoring Bias
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.

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.

+1 Because there are 82 protons.
Explanation:
What would pressure be if volume was 0
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.

what would you expect to see if a piece of copper metal is placed in a solution that contains nickel(II) ions?
A. copper atoms become copper(II) ions
b. nickel ions become solid nickel
c. no reaction happens
d. a precipitate forms that contains copper and nickel ions
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 .

A brick delivery truck parks on a roadside scale that measures 4 m by 6 m. If the brick truck weighs 60 000 N, what pressure does the scale put on the spring below?
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

The dimensions of a cuboid are in the ratio of 1:2:3 and its total surface area is
88m square. Find
the dimensions.
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

Answer:
Equation:
Q = m•C•ΔT
SCIENCE A meteorologist uses a weather map to explain an upcoming change in weather. The map shows a blue line with triangles approaching a red line with semicircles. Based on the map, which weather prediction is most valid? (1 point) A a significant drop in temperature will occur across the area. B There is no chance of precipitation in the forecast. C Warm temperatures will replace cold temperatures. D Humidity levels will rise.
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.

Speed in excess of 100 km/h, which is 208.8 km / h
Further explanationLinear 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
KnownΔx = 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]

Calculate the mass percent of sulfuric acid in a solid sample given a 0.8390g sample of that solid required 32.22 mL of 0.2012 M NaOH for neutralization.
A) 62.11
B) 2.64
C) 37.89
D) 75.78
E) 1.27
Please give an answer and an explanation, thanks!
Answer
C
Explanation:
i remember learning this
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%.
What is percentage by mass?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%.

Which of these would have particles with the highest kinetic energy?
ice
water
water vapor
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
When Silver (Ag) forms a metallic bond with other Silver atoms, what do the valence electrons move into? A. the all go to the same Silver atom B. the bond with the oxygen in the atomsphere C. they escape to free space D. the sea of electrons
Answer:
D. the sea of electrons
Explanation:
Metallic bonds are defined as the bonds formed between two or more metals. Silver atom form metallic bond with other silver atoms.
In metallic bond, the free electrons or valence electrons present in s and p orbitals delocalize. The valence electrons do not move around the atoms or enter the atoms whereas they form a sea of electrons in which they surround the nuclei (positively charged) of the metal ions interacting. The valence electrons are then freely move in the space between the atomic nuclei.
Hence, the correct answer is "D. the sea of electrons".

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.
