N a certain region, the electric potential due to a charge distribution is given by the equation v(x,y,z)=3(x^2)(y^2) +y(z^3) -

2x(z^3), where x,y, and z are measured in meters and v is in volts. calculate the magnitude of the electric field vector at the position (x,y,z)=(1.0,1.0,1.0).

The electric field \mathbf E is the negative of the gradient of the electric potential:

\mathbf E=-\nabla V(x,y,z)=-\left(6xy^2-2z^3,6x^2y+z^3,3yz^2-6xz^2\right)

At the point (1.0, 1.0, 1.0), the electric field has magnitude

\|\mathbf E\|=\|(4.0,7.0,-3.0)\|=8.6\dfrac{\rm V}{\rm m}

Giving 15 points for help!
kolezko [41]

Answer: The correct statements are 'The equation 2n = p should be 2p = n' , 'The actual cost of the onions is $3.00 per pound' and 'Potatoes cost $1.50 per pound.'

Step-by-step explanation:

Here, p represents cost of one potato and n represents the cost of one onion.

And, According to the question,  He purchases 6 pounds of potatoes, p, and 3 pounds of onions, n, for $18.

Therefore, 6p +3n = 18    ------(1)

And, Onions cost twice as much as potatoes.

Therefore, n= 2p ---------(2)

Putting the values of n from 2) in equation 1),

we get, 6p+3(2p)=18

⇒6p+6p=18 ⇒ 12p =18 ⇒ p = 1.5 dollar.

Thus cost of one potato= $1.5

And cost of one onion = $ 2× 1.5= $ 3.00

Thus with help of above explanation we can say that Options first, third and fifth are correct.

Pls help me with this question ​
Andrei [34K]

Answer:

0

Step-by-step explanation:

(sin(2n) − 1) / (sin n − cos n)

-(1 − sin(2n)) / (sin n − cos n)

-(1 − 2 sin n cos n) / (sin n − cos n)

-(sin² n − 2 sin n cos n + cos² n) / (sin n − cos n)

-(sin n − cos n)² / (sin n − cos n)

-(sin n − cos n)

cos n − sin n

Limit as n approaches π/4 is 0.
