Answer:

28

Explanation:

Velocity ratio= Radius of wheel/radius of axle

Radius of wheel= 4.125 inches

Radius of axle= 0.125 inches

Velocity ratio = 4.125/0.125 = 33

Then;

Efficiency = mechanical advantage/velocity ratio × 100

Since the efficiency of the system = 85%

85 = mechanical advantage/33 × 100

Mechanical advantage = 85 × 33/100 = 28

During the phase change, when solid melts into liquid, its temperature remains constant as the heat energy is stored as potential energy. Likewise, as heat is added to a liquid, its temperature increases as the molecules, once again, move faster.

Melting is the physical process where solid gets converted to the liquid phase. When lauric acid was melting heat was added to it, but the temperature did not rise as it was used in breaking the intermolecular forces.

Melting is categorized as a physical change that is reversible. It involves the transition phase of the matter. Here the solids get converted to liquids.

It is a phase change where the heat is added to the object to undergo physical alterations. The heat energy is stored as potential energy in melting.

This energy and heat are used to break the intermolecular forces present in the matter so that the phase of the matter can be converted from solids to liquids.

Therefore, the heat energy in melting is used to break the forces and bonds.

Answer:

newtons 2nd law is the answer

Explanation:

Oxygen-16 and oxygen-18 differ in structure only in that oxygen-18 has two more neutrons in its nucleus than oxygen-16 has.

There are three known stable isotopes of oxygen (8O): 16O, 17O, and 18O. Radioactive isotopes ranging from 11O to 26O have also been characterized, all short-lived.

Answer:

20 m/s

Explanation:

The measurement 45 N represent the magnitude (size) of a force in photograph. Therefore, option C is correct.

The magnitude of the force is the number that represents the force's strength. Assume the force is 10 N in the direction of the east. The direction is indicated by 'towards east,' and the magnitude is indicated by '10'. Magnitude is thus the 'value' or 'amount' of any physical quantity.

The magnitude of force is expressed in mass times length times time squared. The most common metric unit is the newton (N), which is defined as one kilogram times one meter over one second squared.

Thus, option C is correct.

Answer:

Explained below

Explanation:

Newton's law of inertia states that An object at rest will remain continue at rest or if in motion, will continue in motion unless in both cases it is acted upon by a net external force.

Now, If two forces on the rope are equal and opposite forces, then the net force on the rope will be zero and it will not move. Thus,balance force is present in the rope and the rope will remain at rest since the net force is zero or it will continue in motion if already in motion without stopping since net force is zero

However, if the forces are acting in the same direction, it will result in an unbalanced force which means that the net force will be equal to the sum of the two forces and this will result in a stronger force than even the 2 individual forces and consequently it will cause the rope at rest to move, or if the rope is in motion, it will cause it to stop.

Answer:

B. Dipole-dipole

Explanation:

Dipole-dipole is an intermolecular force between polar molecules, where the positive end of one molecule is attracted to the negative end of the second molecule. Polar molecules form dipoles because they contain both electron-rich and electron-deficient regions, thus containing a partial positive pole and a partial negative pole within the same molecule. Examples of molecules that form dipole-dipole interactions include acetone and formaldehyde.

The intermolecular force acting in CH3CH3 is the dispersion forces.

The nature of intermolecular forces between molecules depends on the polarity of the molecules. Nonpolar polar molecules only have weak dispersion forces acting between their molecules.

The molecule CH3CH3 is a nonpolar molecule. Since it is nonpolar, the only intermolecular force acting between its molecules is the weak dispersion forces.

The list of celestial bodies from smallest to largest are asteroids, moons, planets, and Stars.

A celestial body is an occurrence that naturally takes place in space. The terms object and body can be used interchangeably when referring to space and galaxies. Celestial bodies are firmly bound things with intricate shapes and structures that contain hundreds of smaller items.

The sun, moon, stars, and planets are examples of celestial bodies, sometimes known as heavenly bodies. The cosmos contains celestial objects, which are cosmic bodies that are visible in space and are positioned distant from the earth. We can only see the majority of the celestial groupings with a telescope.

They are usually seen at night and are invisible to the unaided eye. The size of certain celestial bodies is considerably greater than that of the planet. They are located outside of the atmosphere of the earth. There are millions of celestial bodies in the Kuiper belt.

Therefore, the list of celestial bodies, from smallest to largest are asteroids, moons, planets, and stars.
