When ionic bonds form compound structures in a solid state, they arrange in latticed, crystalline patterns.

1 answer:

5 0

Answer:

Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound.

Answer:

0 J

Explanation:

If it's at the same temperature then it doesn't need more heat. So it'd be 0 J since it's already at 0C.

A force of 20. newtons to the left is exerted on a cart for 10. seconds.

myrzilka [38]

OK. Thank you. That's an impulse of 200 Newton-sec to the left,
telling us that the cart's leftward momentum increases by 200 kg-m/s
(or its rightward momentum decreases by that amount).

A ductile metal wire has resistance R. Then the wire is stretched to three times its original length. The stretching shrinks the

Ivenika [448]

Explanation:

Let us assume that the final resistance after stretching is $R_{f}$ . Since, the volume of rod does not change and the initial and final volume will be the same as follows.

V = $V_{f}$

$LA = L_{f}A_{f}$

It is given that, $L_{f} = 3L$ .

Therefore, $LA = L_{f}A_{f}$

$LA = 3LA_{f}$

$A_{f} = \frac{A}{3}$

We know that relation between resistance and area is as follows.

R = $\frac{\rho L}{A}$

$R_{f} = \frac{\rho L_{f}}{A_{f}}$

= $\frac{\rho (3L)}{\frac{A}{3}}$

= 9 $(\frac{\rho L}{A})$

= 9R

Thus, we can conclude that the resistance of the stretched wire is 9R.
