So we want to know the mechanical advantage of a machine that has 5 N input force and 25 N out force. Mechanical advantage Ma is the measure of force amplification of some machine. We calculate it by taking the ratio of the output force Fo over the input force Fi. Ma=Fo/Fi=(25 N)/(5 N)=5. So Mechanical advantage for our machine is Ma=5 and the correct answer is the second one.

Explanation</h2>
As we know, the Newton's Second Law of Motion
The F exerted by catapult = 9.35 * 
The Time is = 2.10 s
Velocity of the catapult = 240 km/h = 66.6 m/s (240*1000 m /3600 s)
The mass of jet = ?
First detrmine the acceleration as
{/tex}Acceleration = Velocity/Time {/tex}
Rearrange the formaula as
The mass will be 29495.3 kg
Answer:
Solar power drives Earth's climate. Energy from the sun heats Earth's surface, warms the atmosphere, provides energy for photosynthesis, causes evaporation, drives the weather and water cycles, and powers the ocean currents. ... This circle represents the Earth and the inner-most
The correct answer is:
<span>B) Ionic compounds form charged particles in solution, and electricity will only flow if charged particles are present.
In fact, in ionic compounds ions (which are charged atoms/molecules) are present in the solution, and these free charges can carry the electricity through the solution. Viceversa, in covalent compounds the valence electrons of the atoms are bound togethere between two atoms, so there are no free charges in the solution and electricity cannot flow.</span>
