Astudent working in a grocery store after school pushes several grocery carts together along a ramp. the ramp is 3 meters long and rises 0.5 meter. what is the ideal mechanical advantage of the ramp?

6, mechanical advantage

Explanation:

A student working in a grocery store after school pushes several grocery carts together along a ramp. The ramp is 3 meters long and rises 0.5 meter. What is the ideal mechanical advantage of the ramp?

The ramp is an example of a simple machine

definition of terms

a machine is a device which enables work to be done in a quick and convenient way

mechanical advantage is work input/work output. also the ratio of load to effort

for the question given we simply say

work input/ work output

3/0.5=

6,

mechanical advantage is basically unitless.

positive reinforcement? ?

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
