the amplitude of the wave is which of the following A. Resonance B. Reflection C. Energy D. Magnitude

!WILL GIVE BRAINLIEST!

vazorg [7]

As per angular momentum conservation we can say

$L_i = L_f$

here we know that

$mv_1r_1 = mv_2r_2$

we know that

$v_1 = 1.1 m/s$

$r_1 = 0.6 m$

$v_2 = ?$

$r_2 = 0.15 m$

now from above equation

$2(1.1)(0.6) = 2(v_2)(0.15)$

$v_2 = \frac{(1.1)(0.6)}{0.15}$

$v_2 = 4.4 m/s$

so speed is 4.4 m/s

Why does paper attract both positive and negative charges? Explain.

Sedbober [7]

The fibers have lost electrons giving them a positive charge. The rubber gained electrons giving it a negative charge. The positively charged fibers are now attracted to the negatively charged balloon. The negatively charged balloon attracts the paper.

Calculate the volume of this regular solid. A cylinder labeled B at the top, 13 centimeters high with a radius of 4 centimeters.

Kryger [21]

Answer:

The volume of the cylinder is $653.71\ \text{cm}^3$

Explanation:

Given that,

The height of the cylinder is 13 cm

Radius of the cylinder is 4 cm

We need to find the volume of the cylinder. The formula that is used to find the volume of a cylinder is given by :

$V=\pi r^2 h\\\\V=\dfrac{22}{7} \times (4)^2 \times 13\\\\V=653.71\ \text{cm}^3$

So, the volume of the cylinder is $653.71\ \text{cm}^3$

How is electron movement related to the bonding in sodium chloride? A) The atomic orbitals overlap and share electrons causing a

posledela

Answer: Option (C) is the correct answer.

Explanation:

Sodium has atomic number 11 and its electronic distribution is 2, 8, 1. Whereas chlorine has atomic number 17 and its electronic configuration is 2, 8, 7.

Therefore, we can see that sodium has one extra electron and chlorine has deficiency of one electron.

So, in order to complete their octet sodium will give its one valence electron to the chlorine atom. Hence, there is exchange of electrons and thus it will result in the formation of ionic bond.

Thus, we can conclude that in sodium chloride electron movement is related to the bonding as electrons exchange creating ions to form an ionic bond by electrostatic attraction.
