almond37 [142]

Answer: 1.95

Explanation:

You should start off from the decay formula and solve for τ:

$I = I_{0}e^{\frac{t}{\tau\\ } }$

$\frac{I}{I_{0}} = e^{\frac{-t}{\tau} }$

Apply inverse logarithmic function:

$ln(\frac{0.2 A}{1.2 A} ) = \frac{-t}{\tau}$

The final form will be:

$\tau=\frac{-3.5s}{ln(\frac{0.2A}{1.2A} )}$

Inputing values for I, IO, and t:

$\tau=\frac{-3.5S}{ln(\frac{0.2 A}{1.2 A} )} = 1.95$

A lawyer drives from her home, located 88 milesmiles east and 1818 milesmiles north of the town courthouse, to her office, lo

myrzilka [38]

Answer:

the distance between the lawyer's home and her office is 124 miles

Explanation:

given information:

first lets assume that

x-axis (west = positive, east = negative)

y-axis (north = positive, south = negative)

thus,

distance of the house = (-88,18)

distance of the office = (13, -54)

thus, the distance between the lawyer's home and her office

R = √(x₂ - x₁)² + (y₂ - y₁)²

= √(13 - (-88))² + (-54 -18)²

= 124 miles

What displacement in cm would occur with a 75 N/m spring if you placed a 300 N weight on the spring?

ollegr [7]

Surface tension=75N/m

Weight=300N

$\\ \bull\tt\longmapsto Surface\:Tension=\dfrac{Weight}{Displacement}$

$\\ \bull\tt\longmapsto Displacement=\dfrac{Weight}{Surface\:Tension}$

$\\ \bull\tt\longmapsto Displacement=\dfrac{300}{75}$

$\\ \bull\tt\longmapsto Displacement=4m$

$\\ \bull\tt\longmapsto Displacement=400cm$
