Answer:

67.7 N

Explanation:

Draw a free body diagram of the person on the sled.  There are four forces:

67.7 N  to the right,

friction force to the left,

weight force down,

and normal force up.

Constant velocity means 0 acceleration.

Sum of the forces in the x direction:

∑F = ma

67.7 N − F = 0

F = 67.7 N

Here are a few ideas for a Rube Goldberg machine that closes a fridge door:

A marble rolls down a ramp and hits a small lever.

The lever activates a toy car that rolls down a track and hits a domino.

The domino falls and triggers a chain reaction that results in a weight falling onto a lever.

The lever pulls a string that is attached to a door handle.

The door handle turns and the fridge door closes.

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) \(\rightarrow\) Consumers

    Decomposition \(\downarrow\)               \(\downarrow\) 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:

My answer to the question is option C.

A balanced chemical equation reflects the idea that the mass of the products is equal to the mass of the reactants. The correct option is C.

In a balanced chemical equation, the mass of the products must be equal to the mass of the reactants.

According to the law of conservation of mass, in a chemical reaction, the mass of the products must be equal to the mass of the reactants because matter cannot be created or destroyed, it only can be transformed.

For example, for the given reaction:

CH₄ + 2O₂ → CO₂ + 2H₂O

The mass of the reaction is:

\( m_{CH_{4}} + m_{O_{2}} = m_{CO_{2}} + m_{H_{2}O} \)

So the sum of the masses of the reactants must be equal to the sum of the masses of the products.

Therefore, the correct option is C.

Explanation:

The reason behind why people in the smaller car  are more likely to get injured than those in the large one is greater acceleration of the small car.

Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. Si unit of acceleration is meter/second² (m/s²).

When There was a head-on collision between a compact hybrid car and a SUV, according to Newton’s 3rd law, the force exerted on each other is the same. But .

As from  Newton's 2nd Law, we know that numerical value of force is simply multiplication of mass and acceleration. So, due to having small mass, smaller car suffers more acceleration for same amount of unbalanced force.

This acceleration acts against current inertia of motion of both cars and try to change it. As small car has greater acceleration, people in the smaller car are more likely to get injured than those in the large one although  both cars are equally strong.

Explanation:

The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.

The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. There is no known limit for long and short wavelengths. Extreme ultraviolet, soft X-rays, hard X-rays and gamma rays are classified as ionizing radiation because their photons have enough energy to ionize atoms, causing chemical reactions. Exposure to ionizing radiation can be a health hazard, causing radiation sickness, DNA damage and cancer. Radiation of visible light and longer wavelengths are classified as nonionizing radiation because they have insufficient energy to cause these effects.

Throughout most of the electromagnetic spectrum, spectroscopy can be used to separate waves of different frequencies, producing a spectrum of the constituent frequencies. Spectroscopy is used to study the interactions of electromagnetic waves with matter.[4]

The total amount you'll end up paying is $8,119.78, which is more than the amount you're borrowing. This is because the interest on the loan adds up over time.

They are offering you a loan of $7,000 with an interest rate of 6.5%. The loan term is 48 months, which means you have four years to repay the loan.

Based on these terms, your monthly payments will be $170.41.

However, the total amount you'll end up paying is $8,119.78, which is more than the amount you're borrowing. This is because the interest on the loan adds up over time.

To put it simply, the dealership is lending you $7,000, but they are also charging you 6.5% interest on the amount you borrow. This means that for every month you keep the loan, you'll pay some interest, which adds up over time. By the end of the 48-month loan term, you'll have paid back the $7,000 you borrowed, plus the additional $1,119.78 in interest.

So, before you decide to accept the loan offer, it's important to understand the total cost of the loan and whether the monthly payments fit into your budget. You may also want to shop around and compare loan offers from different lenders to find the best deal for you.

Therefore, you'll have paid back the $7,000 you borrowed, plus the additional $1,119.78 in interest. which is greater than the borrowed.

Forty million years ago, the continent of India, which was being carried northward by the Indo-Australian plate, collided with Asia forming the Himalayan mountain range (fold mountains). Since the initial encounter, the subcontinent of India has moved 2,000 kilometers farther north at a rate of 5 centimeters a year, sliding beneath Asia as it moves. In 10 million years India will plow into Tibet a further 180km. This is about the width of Nepal.

In an analogy of a circuit with a resistance to an obstacle race, we can consider various elements of the race as representative of different components of the circuit.Obstacles, Track or Route, Participants, Start and Finish Line.

Obstacles: The obstacles in the race represent the resistors in a circuit. Just as resistors impede the flow of current in a circuit, obstacles in the race create hurdles that slow down the participants. The difficulty or magnitude of the obstacles can be equated to the resistance value of the resistors in a circuit.

Track or Route: The race track or route itself can be seen as the conductive path in a circuit. It provides a pathway for the participants to move and complete the race. Similarly, the conductive path in a circuit allows the flow of current from the power source to the load.

Participants: The people participating in the race represent the flow of electrons in a circuit. Just as the participants move through the obstacles in the race, electrons move through the resistors in a circuit. The rate at which participants complete the race can be compared to the current flowing through the circuit.

Start and Finish Line: The start and finish line of the race correspond to the terminals of a circuit. The start line represents the positive terminal, where the participants begin their journey, and the finish line represents the negative terminal, where the race concludes.
