While researching machines and how they work, tika finds several online sites that discuss how force and distance are related to work done by a machine.

how should tika most likely describe this relationship between force and distance to her study group?

if the input force is less than the output force, then the input distance must be greater than the output distance.
if the input force is greater than the output force, then the input distance must be greater than the output distance.
if the input force is less than the output force, then the input distance must be the same as the output distance.
if the input force is equal to the output force, then the input distance must be greater than the output distance.

The right answer for the question that is being asked and shown above is that: "If the input force is greater than the output force, then the input distance must be greater than the output distance." Tika most likely describe this relationship between force and distance to her study group is that If the input force is greater than the output force, then the input distance must be greater than the output distance.

Answer: it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.explanation: we have equation of motion $s=ut+\frac{1}{2} at^2$ ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/s $s=0*t+\frac{1}{2} *2.18*t^2$ $s=1.09t^2[/ 2equating equation 1 and 2 [tex]4.75t = 1.09t^2\\ \\ t=4.36 seconds.$ so it will take 4.36 seconds to reach her average velocity 10.69 miles/hour.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
