Part A Choose a tool or a device you can investigate. It must not have any source of power other than the person using it. It must use one or more of the six simple machines. Explain how the tool or device is used. What work does a person do while using it? What kind of motion do we see when it’s used?

Part B
Which simple machines are used in the tool or device?

Part C
What materials are used to make the tool or device? Why did the designers pick those materials?

Part D
Question
Draw the tool or device, and label where the input force is exerted and where the output force is exerted.

Part E
Mechanical advantage is the ratio of output force to input force. Does the tool or device have a mechanical advantage that is greater than 1, equal to 1, or less than 1? Do some research on the Internet or at a library if you aren’t sure.

Part F
Suggest one or more improvements that designers could make to the tool or device.

sorry bud but I don´t answer questions I just still your loot/points

Explanation:

need to see circuit to get time constant

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
