Answer:when a chemical reaction occurs with only one substance, the atoms of that substance rearranges to form new bonds to make the products.

Explanation: During chemical reaction, the bonds between the reactants are broken and the atom bonds in new ways to form products that are chemically and physically different from the reactants.

Example is the breakdown reaction of hydrogen peroxide(the reactant) into water and oxygen( products). Here, 2 molecules of hydrogen peroxide is broken down to form 2 molecules of water and one molecule of oxygen. The atoms that started out in the hydrogen peroxide molecules are rearranged to form water molecules and oxygen molecules.

Answer:

The atoms of the substance are rearranged

Explanation:

When a chemical reaction involves only one substance, the atoms of the reactant substance rearranges to yield the product substance(s).

Chemical bonds in the reactant substance are broken and new bonds are formed as the atoms in the reactant substance forms the product substance (s).

A car traveling at 30 m/s speeds up to 35 m/s over a period of 5 seconds. What is the acceleration of the car?
Delvig [45]

Answer:

u =30 m/s

v = 35 m/s

t = 5 secs

Explanation:

a = (v- u)/t

a = (35-30)/5

a = 5/5

a = 1 m/s^2

What are 3 different forces that act on objects on the earth ΩvΩ
Stolb23 [73]
A force is a push or pull acting upon an object as a result of its interaction with another object. There are a variety of types of forces. a variety of force types were placed into two broad category headings on the basis of whether the force resulted from the contact or non-contact of the two interacting objects.

Contact Forces

Action-at-a-Distance Forces

Frictional Force
Gravitational Force
Tensional Force
Electrical Force
Normal Force
Magnetic Force
Air Resistance Force
Applied Force
Spring Force


These are types of individual forces

Edge 2020 waves and diffraction lab report d a t a ​
Sever21 [200]

Answer:Theoretical Discussion

The diffraction of classical waves refers to the phenomenon wherein the waves encounter an obstacle that fragments the wave into components that interfere with one another. Interference simply means that the wave fronts add together to make a new wave which can be significantly different than the original wave. For example, a pair of sine waves having the same amplitude, but being 180◦ out of phase will sum to zero, since everywhere one is positive, the other is negative by an equal amount.

A marble rolling at a speed of 2.71 m/s falls of the end of a table that is 1.25 m high. How far from the base of the table does
katrin [286]

Answer:

The marble lands at a distance of 1.36 m from the base of the table.

Explanation:

The motion of the marble falling off the table is a projectile with initial velocity in the horizontal direction only.

The motion can be solved in two directions, the horizontal and vertical direction.

Along the vertical direction, the initial velocity is 0 m/s as it has only horizontal component initially. Also acceleration in the vertical direction is acceleration due to gravity.

Let us use equation of motion in vertical direction.

y-y_0=v_{0y}t+\frac{1}{2}at^2

Where,

v_{0y}\rightarrow \textrm{vertical component of the initial velocity}.\\y\rightarrow \textrm{final position of the marble}\\y_0\rightarrow \textrm{initial vertical position}\\a_y\rightarrow \textrm{acceleration in the vertical direction}\\t\rightarrow \textrm{time taken to reach bottom}

Now, plug in 0 for y, 1.25 for y_0, 0 for v_{0y}, -9.8 for a_y. This gives,

0-1.25=0+\frac{1}{2}(-9.8)t^2\\-1.25=-4.9t^2\\t^2=\frac{-1.25}{-4.9}\\t^2=0.255\\t=\sqrt{0.255}=0.501\ s

Therefore, time to reach bottom is 0.501 s.

Now, consider the horizontal motion. There is no acceleration in the horizontal direction. So, distance is given as the product of horizontal velocity and time taken.

Horizontal distance covered by the marble is given as:

x=v_{0x}\times t=2.71\times 0.501=1.36 \textrm{ m}

Therefore, the marble lands at a distance of 1.36 m from the base of the table.
