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.

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.

Explanation:

Answer:

h = 10 cm

Explanation:

The magnification produced by a mirror is given by :

[tex]m=\dfrac{h'}{h}[/tex]

h' is the image size and h is the object size

We have, h = 10 cm, m = +1

So,

[tex]m=\dfrac{h'}{h}\\\\h=\dfrac{10}{1}\\\\h=10\ cm[/tex]

So, the size off the object is same as that of the size of the image i.e. 10 cm.

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.

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)

∑F = -250 N

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 .

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.

Answer:

Taking water and oxygen from Earth is rather expensive and hard to do.

Explanation:

Without water and oxygen, travel to other planets is basically impossible

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.

 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:

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.

The mass of cylinder made up of alloy of platinum iridium that is kept at international bureau of weights and measures is called one standard kilogram.

The system of seven fundamental quantities is called SI system .

The element that is least likely to form bonds is found in group 18. Thus, the correct option for this question is D.

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.

Explanation:

Given:

Δx = 100 m

v₀ = 0 m/s

a = 2 m/s²

Find: t

Δx = v₀ t + ½ at²
