The manufacturer of a 1.5 V D flashlight battery says that the battery will deliver 9 mA for 40 continuous hours. During that ti

Jet001 [13]

Answer:

a) 144.000 s

b) and c)Battery voltage and power plots in attached image.

$V=-\frac{0.5}{144000} t + 1.5 V[tex] [tex]P(t)=-(31.25X10^{-9}) t+0.0135$ where D:{0<t<40} h

d) 1620 J

Explanation:

a) The first answer is a rule of three

$s=\frac{3600s * 40h}{1h} = 144000s$

b) Using the line equation with initial point (0 seconds, 1.5 V)

$m=\frac{1-1.5}{144000-0} = \frac{-0.5}{144000}$

where m is the slope.

$V-V_{1}=m(x-x_{1})$

where V is voltage in V, and t is time in seconds

$V=m(t-t_{1}) + V_{1}$ and using P and m.

$V=-\frac{0.5}{144000} t + 1.5 V[tex] c) Using the equation VPOWER IS DEFINED AS:[tex] P(t) = v(t) * i(t) [tex]so.[tex] P(t) = 9mA * (-\frac{0.5}{144000} t + 1.5) [tex][tex]P(t) = - (31.25X10^{-9}) t + 0.0135$

d) Having a count that.

$E = \int\limits^{144000}_{0} {P(t)} \, dt = \int\limits^{144000}_{0} {v(t)*i(t)} \, dt$

$E = \int\limits^{144000}_{0} {-\frac{0.5}{144000} t + 1.5*0.009} \, dt = 1620 J$

When the value of the output cannot be determined even if the value of the controllable input is known, the model is:_________

Nuetrik [128]

Answer:

<em>c. stochastic.</em>

Explanation:

A stochastic model is a tool in statistics, used to estimate the probability distributions of intended outcomes by the allowance of random variation in any number of the inputs over time. For a stochastic model, Inputs to a quantitative model are uncertain, and the value of the output from a stochastic model cannot be easily determined, even if the value of the input that can be determined is known. The distributions of the resulting outcomes of a stochastic model is usually due to the large number of simulations involved, and it is widely used as a statistical tool in the life sciences.
