Answer:

Q=It

and

p=IV

Given, v=9V P= 7W

I=P/V

I =7/9

Also, time(t) from 9am to 12pm is 3hrs

Converting into sec =3×3600

t=10800

Q= 7/9 ×10800

Q =8400C

MAXImum [283]

Answer:

Yes

Explanation:

A nonlinear optimization problem is indeed a optimization problem in which there are nonlinear elements involved either as the objective function or one or more constraints may be nonlinear also. Let me show you an example. Let optimize de following function:

f(x) = x_{1} +x_{2}

These are the constraints:

x_{1} \geq  0\\x_{2} \geq  0\\\\x_{1} ^{2} +  x^{2}_{2}  \geq  1

The last constraint consists on nonlinear elements, so this problem in fact a nonlinear optimization problem.
