Answer:

Work done, W =1520 J

Explanation:

We have,

The brakes on a bicycle apply 95 N of force to the wheels. When the  brakes are applied, the bicycle comes to a stop in 16 m.

It is required to find the work done by the brakes on the wheels. We know that the product of force and displacement is equal to the work done. It is given by :

\(W=Fd\\\\W=95\times 16\\\\W=1520\ J\)

So, the work done by the brakes is 1520 J.

According to the Kinetic Molecular Theory of Matter, the temperature of a substance is directly proportional to the average kinetic energy of the particles that make up the substance.

When a liquid thermometer measures something that is hot, the particles in the hot substance have a higher kinetic energy than the particles in the liquid thermometer. This causes the particles in the liquid thermometer to gain kinetic energy and move faster. As they move faster, they take up more space, causing the liquid to expand and rise in the thermometer.

On the other hand, when a liquid thermometer measures something that is cold, the particles in the cold substance have a lower kinetic energy than the particles in the liquid thermometer. This causes the particles in the liquid thermometer to lose kinetic energy and move slower. As they move slower, they take up less space, causing the liquid to contract and fall in the thermometer.

Therefore, when a liquid thermometer measures something that is hot, the liquid expands and rises in the thermometer, and when it measures something that is cold, the liquid contracts and falls in the thermometer.

Explanation:

mars has a shorter year because when it revolves around the sun, it takes less time than, saturn who is millions of miles away from mars, longer. Also, mars is closer to the sun than saturn

The main difference between Mars and Saturn is Mars has a relatively shorter year and a higher atmospheric temperature than Saturn. Hence B option is correct.

One of our solar system's most studied planets is Mars. Mars is the fourth planet from the sun and features two peculiar moons in addition to a distinctive rusty red look.

Inside our solar system, there is a frigid, arid planet called the Red Planet. While it has a relatively thin atmosphere, the dusty, (as far as we can tell) dead planet is everything from boring.

Extreme dust storms may cover the whole planet, the atmosphere's carbon dioxide can get so frigid that it turns straight into snow or ice, and marsquakes—a Mars-version of earthquakes—regularly rumble the surface. Consequently, it is not surprising that scientists are still fascinated by this little red pebble.

Hence option B is correct.

Z.M. says: I am building a small engine with link motion New shoots come up, but they in turn are killed off long before maturity. and no the golf ball is not denser even tho it sinks

Explanation:

Any two objects that have mass attract each other with a force we call gravity.  You probably never noticed this for small objects, because the force is so weak.  But the Earth has lots of mass, and so it exerts a big gravitational force on you.  We call that force your weight.  The fact that gravity is actually a force of attraction is not obvious.  Prior to the work of Isaac Newton, it was assumed that gravity was simply the natural tendency of objects to move downward. this is why they

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.

1: Equilibrium

[] When two forces are equal in opposite directions, they are in a state of equilibrium

2: Friction

[] It can be hard to sometimes slide a paper across a table, roll a car across the ground, etc etc. This is because of a force called friction which resists motion

3: Displacement

[] Work is only "done" when the object or surroundings are having movement, or in motion, and this creates displacement

4: Force

[] A force is a push/pull in any direction, this is a simple definition so not much can be added.

5: Inertia

[] Inertia is a force that likes to remain unchanged, or without movement

6: Effort

[] "Meg is holding up weight without movement. She hasn't done any work since it did not move, but is tired. Why?" Effort! She still put in effort even though no "work" happened

7: Work

[] Force times displacement is the equation for work

8: Motion

[] Look back to #3, when there is motion we can tell work is done

The Correct choice is ~

The other three (Neutrons, Protons, and Electrons) are subatomic particles found inside an atom, where as the Molecules are substances that have atoms as it's constituent particles.

The requried, molecules are not tiny particles. Option D is the right choice.

An atom is the smallest unit of matter that retains the properties of an element. Atoms are composed of three types of subatomic particles: protons, neutrons, and electrons.

Here,
Molecules are not tiny particles that are parts of atoms. Rather, they are formed when two or more atoms combine chemically.

Neutrons, protons, and electrons, on the other hand, are the three types of particles that make up atoms. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus. These subatomic particles are responsible for the properties and behavior of atoms and the elements they form.

Thus, the requried, molecules are not tiny particles. Option D is the right choice.

Answer:

Air always moves from high-pressure places to low-pressure places. This means air moves from denser air to less dense air. This movement of air results in wind. If, for example, there was an area of high-pressure air east of an area of low-pressure air, then the wind would be coming in from the east.

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
