At 8 am i make a cup of tea for myself and measure its temperature to be 94° c, ten minutes later the temperature is measured to be 82° c. the ambient temperature is a constant 20° c. if i like my tea not too hot (70° c), and yet not too cold (60°c), then what is the time window i have to begin drinking? use the differential form of newton's law of cooling, and give times to the nearest minute.

it breaks and dirupture other materials and other sencews from the bottom

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

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
