Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.

Explanation:

Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

Answer:

, if we see we are considering this initial mass of this in this particular case, the initial mass of substantiated- or we can say, mercury oxide heated, it is, we can say, 27 grains. So this is the initial mass which is heated here. It is like this and what we can say we can consider this consent, passion of mass, so consummation of mass. We are looking here, the log, the conservation of the mass, so conservation of mass state at mass. It is always converted, but if it's not the case, we can also modify it it through mass and energy. They are combined converted or we can say, mass energy equivalence here so mass. It is confirmed in this case, so we can say, but here it is said that initially mass was 27 gram and finally mass was 25 gram. So but as we know, mass it is conserved mass, it is always conserved, so if the mass it is conserved, we should say this thing that the lost in the 2 gram weight must be due to the evaporation or we can say formation of the gases which Have been escaped, that is why it cannot be recorded, so we can say 2 gramos in the mass to the escape of the gas, or we can say evaporation. So.

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.

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity

Answer:

4,000x10^2 N/M

The spring constant of the spring is  402.84 N/m.

The period of oscillation is the shortest amount of time after which the motion of the particle repeats. The period of oscillation is the length of time it takes for a particle to complete its to-and-fro motion.

Given parameters:

Mass of the double coconut: M = 20.0 kg.

Time period of oscillation = 60/42.7 second = 1.405 second.

From, \(T = 2\pi \sqrt{\frac{m}{k} }\) we can write:

k = 4π²m/T²

=  4π²(20/1.40²) N/m

= 402.84 N/m.

Hence,  The spring constant is  402.84 N/m.

The force from the barrier is transferred into the object, in this case, a ball, causing it to roll back when it rolls off of another surface (with rolling friction) because of newton's third law.

Newton's third law asserts that when two bodies interact, they exert forces that are equal in size and directed in the opposite direction. Another name for the third law is the law of action and reaction.

This equation is crucial for understanding issues with static equilibrium, where all forces are in balance, but it also holds for bodies moving at a constant or accelerated speed. It doesn't only use bookkeeping methods; the forces it represents are actual forces. For instance, a book laying on a table exerts downward pressure equal to the weight of the book on the table. The third law exerts an equal and opposite force on the book.

Answer: Explanation:

Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

The faster an object is going, the more resistance there will be. An example of this would be if you're running the faster you run, the more air is going against you.

Answer:

1. She is moving at a speed of \(147.18 ms^{-1}\).

2. The speed of the golf ball is \(78.1 m/s\).

Explanation:

1. We can say , at any moment the skydiver is having a kinetic energy of \(1/2 mv^2\)

(where, \(m\) is her mass and \(v\) is the velocity at that point)

Given, \(1/2mv^2 =704000\)

and, \(m = 65KG\)

So, putting the values we get,

\(v=147.18 ms^{-1}\)

2. \(KE=\frac{1}{2} mv^2\)

\(143.3J =\frac{1}{2} (.047)v^2\)

\(v^2=6097.9 m^2/s^2\)

\(v=78.1 m/s\)

Mass of the roller coaster = 1000 kg

Velocity of the roller coaster = 20.0 m/s

We know the formula for finding the kinetic energy is

Kinetic energy = 0.5 * mass * (velocity) ^2

                      = 0.5 * 1000 * (20)^2

                      = 0.5 * 1000 * 400

                      = 200000 Joules
