In a real system of levers, wheels, or pulleys, the AMA is less than the IMA because _____.

grandymaker [24]

In a real system of levers, wheel or pulleys, the AMA (actual mechanical advantage) is less than the IMA (ideal mechanical advantage) because of the presence of friction.

In fact, the IMA and the AMA of a machine are defined as the ratio between the output force (the load) and the input force (the effort):
$IMA= \frac{F_{out}}{F_{in}}$
however, the difference is that the IMA does not take into account the presence of frictions, while the AMA does. As a result, the output force in the AMA is less than the output force in the IMA (because some energy is dissipated due to friction), and the AMA is less than the IMA.

Why do you think ionic bonds are generally weaker than covalent bonds?

serious [3.7K]

<span> The short answer is that they are not always weaker in fact. Some ionic compounds have very strong bonds, while some covalent bonds are quite weak. Usually however, it is easier to break an ionic bond than a covalent one. What determines the actual strength of a bond is quite complex, but let me try to explain the basic principles. this is the best answer i can come up with</span>

As a positively charged object moves toward a negatively charged object, their potential energy increases. As a positively charg

Zielflug [23.3K]

Answer:

As a positively charged object moves toward another positively charged object, their potential energy increases. True

As a negatively charged object moves toward another negatively charged object, their potential energy increases True

Explanation:

When two like charges move towards each other, there is increase in potential energy because the motion is in opposition to the direction if the field. Hence when two negative or two positive charges move towards each other, there is an increase in potential energy.

However, potential energy is inversely related to the distance of separation of the charges.

At one instant, an object moving downward in free fall on the Earth has a speed of 50 m/s. Its speed 1 second later is

maksim [4K]

Answer:

velocity 1 second later = 59.8 m/s

Explanation:

Velocity final = Velocity initial + acceleration • time

Velocity final = 50m/s + 9.8m/s/s • 1s

Velocity final = 59.8 m/s
