Why does stone take so long to cool?
Answer:
Stone has what's called a high thermal conductivity, which is simply a fancypants way of saying that it allows heat to flow through it quickly. For example, suppose the piece of stone in question is at room temperature, or 70 degrees. Your body likes to keep an average toasty temperature of 98.6F.
How long would it take you too run the 100m sprint if from rest you accelerate at 2m/s/s for the whole race?
Answer:
10 s
Explanation:
Given:
Δx = 100 m
v₀ = 0 m/s
a = 2 m/s²
Find: t
Δx = v₀ t + ½ at²
100 m = (0 m/s) t + ½ (2 m/s²) t²
t = 10 s

1. Reflection Question: What are some actions or activities that can affect your heart rate and respiratory rate and cause either or both of them to increase or decrease?
Answer:
There are following two activities which affect heart rate and respiratory rate.
1-Exercise
2-Hiking
Explanation:
when we are exercising or hiking our heart rate and respiratory rate affected. This is because during hiking and exercising our body may need three or four time your normal cardiac output. This is because our body consuming energy during the workout and our muscles needs more oxygen. To meet the need of energy and oxygen respiration rate become fast and heart rate also increase.

If a questions says "at what point does the ball stop?" what is it asking for?
Explanation:
If a question says "at what point does the ball stop?", it means we need to find the position of the ball when its final velocity is equal to 0. It can be calculated using the equation of kinematics as follows :
d = ut + (1/2) at²
and
v²-u²=2ad
Where, u is initial velocity, v is final velocity, a is acceleration, t is time and d is displacement.

For writing a scientific lab report, when you write the discussion do you need to include every single result in your data? Or do you just include a summary of your data?
Answer:
include a summary of data
Explanation:
In writing a scientific laboratory report, only the summary of the data is included in the discussion and not the entire result.
The discussion section of a lab report deals with the interpretation and explanation of findings during the course of the experiment in relation to the background information leading to the experiment/research. Hence, only the summary of the data generated is required. The detailed results are usually reported in the result section, not the discussion section.

describe how changing the particles changed the atom
Answer: During chemical changes particles do change with atoms or ions regrouping . Bonds (links) between atoms break and new ones form and energy is either given out or taken in.
Explanation:
Chemical reactions make particles to change and resulting to change atoms or ions via regrouping .
What is chemical reaction?The chemical reaction is the reaction between two reactants that led to the formation of products.
The products are substances that forms after reaction. The reactants are the substances which are original materials.
Bonds between atoms break and make new ones. In this process, energy is either rejected or taken in.
The particle are the electrons which are shared between the atoms of same or different elements.
The electrons in the valence get donated or accepted by the atoms and form bond. When the electrons are donated, the bonds break and when electrons are accepted, bonds are formed. So, the new element or compound is formed.
Thus, the chemical reaction are responsible for change in atoms due to change in particles.

An object is moving along a straight line. The graph shows the velocity of the object over
time.
What is the instantaneous acceleration of the object at time = 9.5 seconds?
A.-20 m/s2
B.0 m/s2
C.20 m/s2
D.-10 m/s2
Answer:
From 9 to 10 sec the velocity is decreasing at a constant rate.
Change in V = 20 m/s - 30 m/s = -10 m/s
Since acceleration is constant from point E to point F (straight line)
and t = 9.5 sec is on this line
a = (20 m/s - 30 m/s) / 1 sec = -10 m/s^2
The instantaneous acceleration of the object at time = 9.5 seconds is - 10 m/s².
What is acceleration?Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.
From t = 9 second to t =10 second the velocity of the object decreases at a constant rate.
Change in velocity of the object = final velocity - initial velocity
= 20 m/s - 30 m/s
= -10 m/s
time interval is = 10 sec - 9 sec = 1 sec.
Hence, acceleration of the object is: a = Change in velocity/ time interval
= - 10 m/s/1s
= -10 m/s²
Therefore, the instantaneous acceleration of the object at time = 9.5 seconds is - 10 m/s².

An object of mass 30 kg is falling in air and experiences a force due to air resistance of 50 newtons. Determine the net force acting on the object:
Explanation:
Draw a free body diagram. There are two forces: weight force pulling down and air resistance pushing up.
Sum the forces in the y direction:
∑F = 50 N − (30 kg) (10 m/s²)

The friction of the water on a boat produces an acceleration of -10 m/s2. If the
boat is traveling at 30 m/s and the motor is shut off, how long does it take the boat
to slow down to 5.0 m/s?
a
2.5 s
b 2.35
c
2.2 s
d
2.0 s
Answer:2.5s
Explanation:
Idk I guessed and got it right
Friction is the force that exists between two surfaces that are sliding or attempting to slide across each other.
The acceleration produced by the friction of water is a = [tex]-10 m/s^2[/tex]
The boat takes 2.5 seconds to slow down.
What causes of friction?Surface roughness: When two rough surfaces collide, they generate frictional force or an opposing force, which can sometimes be converted into heat. Body deformation: Deformations in the body or the surface of the body in contact may cause friction during motion.Friction is the force that exists between two surfaces that are sliding or attempting to slide across each other. For example, friction makes it difficult to push a book across the floor. Friction always acts in the opposite direction that the object is moving or attempting to move.The equation that rules the change of velocities is:
[tex]V = V _0 + at[/tex]
Where:
a = acceleration
Vo = initial speed
v = final speed
t = time
The acceleration produced by the friction of water is a = [tex]-10 m/s^2[/tex] and the boat is initially traveling at v=30 m/s. When the motor is shut off, the boat will start braking until it stops. We need to find the time it takes to ready the final speed of v=5 m/s.
t = [tex]\frac{V - V_0 }{a}[/tex] = -5-30 /10 = 2.5 s.
The boat takes 2.5 seconds to slow down.

Answer:
It is spinning, making the ball a little more airborn than the one that isn't spinning
Answer:
A spinning ball creates a Centrifugal Force because it is given the "energy" so to speak to spin. A ball that is not moving does not need any external energy to keep it still or, in other terms, at rest.

The elements least likely to form bonds are found in which group?
O 15
O 16
017
O 18
The element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.
What is group 18 of the periodic table known?The elements of group 18 in the modern periodic table are known as noble gases. These gases are colorless, odorless, tasteless, and nonflammable under standard conditions.
They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
Due to this fact, they would not have any ability to form bonds with other elements in order to produce compounds or molecules. They are the most stable elements because they have a full outer shell of valence electrons, so they have no need to bond with other elements.
Therefore, the element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.
