Explanation:

MONOMERS

Answer:

B

Explanation:

moving a car requires energy from gas, growing a plant requires energy from the sun, and getting a tan requires energy from the sun. So it must be a stationary inanimate object.

Answer: D

Explanation: Look at the figure, we can conclude that the correct answer is

X: Low potential energy

Y: High potential energy

Z: Flow of electrons

Because electrons flow where there is difference in potential energy. And electrons move from a region of high potential energy to a region of low potential energy.

Since the arrow is pointing to X, that means

Z is the flow of electrons, X is of low potential energy and Y is of high potential energy.

Answer:

5.024×10⁻⁵ m

Explanation:

A = πr²................ Equation 1

Where A = cross sectional area of the wire, r = radius of the wire, π = pie.

Given: r = 4.0×10⁻³ meter.

Constant: π = 3.14.

Substitute these values into equation 1

A = 3.14(4.0×10⁻³)²

A = 3.14×16×10⁻⁶

A = 50.24×10⁻⁶

A = 5.024×10⁻⁵ m.

Hence the cross sectional area of the wire = 5.024×10⁻⁵ m

The cross sectional area of this wire will be "5.024 × 10⁻⁵ m". To understand the calculation, check below.

According to the question,

Radius of silver wire, r = 4.0 × 10⁻³ m

Constant, π = 3.14

We know the formula,

→ Area will be:

A = πr²

By substituting the above values,

  = 3.14 × (4.0 × 10⁻³)²

  = 3.14 × 16 × 10⁻⁶

  = 5.024 × 10⁻⁵ m

Thus the above answer is right.

hy how are you now this is 2020 question but now it is 2022

Answer:

1.) V = 12t^3 - 120t^2 + 252t

2.) No

3.) At positive V and negative V

Explanation: Given that the position of an object at any time t is s(t)=3t4−40t3+126t2−9.

1.) To determine the velocity V, we will differenciate the equation above with respect to t.

V = ds/dt

ds/dt = 12t^3 - 120t^2 + 252t

Therefore,

V = 12t^3 - 120t^2 + 252t

2.) The equation above depict an exponential equation which proves that the object never stops changing.

3.) The object moves to the right at positive velocity V and moves to the left at negative velocity V

i. The velocity of the object at any time is V = 12t^3 - 120t^2 + 252t

ii. The object is Not changing.

iii. At positive V and negative V.

Since the position of an object at any time t is

s(t)=3t4−40t3+126t2−9.

1.

Here the velocity is

V = ds/dt

ds/dt = 12t^3 - 120t^2 + 252t

SO,

V = 12t^3 - 120t^2 + 252t

2.) The equation above represents an exponential equation that proves that the object never stops changing.

3.) The object moves to the right at positive velocity V and moves to the left at negative velocity V

Answer:

Batteries have the positive end Cathode, and a negative end of anode. There is also an electrolyte that allows electrical charges to go from the cathode to the anode.  

-Anode most often is made of zinc  

- Manganese dioxide as Cathode.  

- the electrolyte contains ions

Explanation:

GIVE THE OTHER DUDE BRAINLIEST

A battery is made up of three parts. The Cathode (positive end +), the Anode (negative end -), and the electrolyte.

Batteries have a negative end called the anode and a positive end called the cathode. Another electrolyte facilitates the transfer of electrical charges from the cathode to the anode.

Between the cathode and anode, electrical charges can move thanks to the electrolyte. The flow of electricity that results from these chemical reactions provides the electrical voltage potential needed to power a circuit.

The following list includes typical battery materials.

- Zinc is typically used to make anodes.

- The cathode is manganese dioxide.

- There are ions in the electrolyte inside and between.

Therefore, three components make up a battery. The electrolyte, the cathode (positive end +), and the anode (negative end -).

Answer: Speeding Up

Explanation:

Force is proportional to the acceleration of an object. The greater the force, the more acceleration will be produced.

When the force on the tire is equal to the weight of the car, the car is reaching a stability as a result of increase in motion.

But when the force of the load on the tire is quite large(most likely several times the weight of the car) and is directed forward, then, the car is at high speed.

Answer:

c

Explanation:

The step that has been missing in the carbon cycle has been decomposition, as it breaks the organic matter into simpler carbon that can be absorbed. Thus the correct option is C.

The carbon cycle can be defined as the transfer of carbon in varying forms in the atmosphere. Carbon has been present in the atmosphere in the form of air.

The air has been taken up by the plants for the formation of glucose. The atmospheric carbon has been converted into sugars by photosynthesis.

The sugar has been taken up by the consumers and is released back into the earth from the decomposition of the plants and waste from consumers or by the combustion process.

The carbon cycle can be given as:

Photosynthesis (Food) [tex]\rightarrow[/tex] Consumers

    Decomposition [tex]\downarrow[/tex]               [tex]\downarrow[/tex] Combustion

                            Carbon dioxide

The step that has been missing in the carbon cycle has been decomposition, as it breaks the organic matter into simpler carbon that can be absorbed. Thus the correct option is C.

Answer: 16.3 seconds

Explanation: Given that the

Initial velocity U = 80 ft/s

Let's first calculate the maximum height reached by using third equation of motion.

V^2 = U^2 - 2gH

Where V = final velocity and H = maximum height.

Since the toy is moving against the gravity, g will be negative.

At maximum height, V = 0

0 = 80^2 - 2 × 9.81 × H

6400 = 19.62H

H = 6400/19.62

H = 326.2

Let's us second equation of motion to find time.

H = Ut - 1/2gt^2

Let assume that the ball is dropped from the maximum height. Then,

U = 0. The equation will be reduced to

H = 1/2gt^2

326.2 = 1/2 × 9.81 × t^2

326.2 = 4.905t^2

t^2 = 326.2/4.905

t = sqrt( 66.5 )

t = 8.15 seconds

The time it will take for the rocket to return to ground level will be 2t.

That is, 2 × 8.15 = 16.3 seconds

Answer:

The new force between the charges becomes double of the initial force.

Explanation:

The force acting between charge particles is given by :

[tex]F=k\dfrac{q_1q_2}{r^2}[/tex]

k is electrostatic constant

r is distance between charges

If one of the charges are doubled, then, q₁ = 2q₁

The new force becomes,

[tex]F'=\dfrac{2kq_1q_2}{r^2}\\\\F'=2F[/tex]

So, the new force between the charges becomes double of the initial force.

Answer:

1.2

Explanation:

Data obtained from the question include:

Velocity of light in the oil (V) = 2.5x10^8m/s

Velocity of light in air (C) = 3x10^8m/s

Refractive Index (n) =.?

The rafractive index (n) for the oil is given by:

Rafractive index (n) = Velocity in air (V) /velocity in oil (V)

n = C/V

n = 3x10^8 / 2.5x10^8

n = 1.2

Therefore, the Refractive Index of the oil is 1.2.
