<h3><u>Answer;</u></h3>

<em>D) transferring electrons</em>

The electrostatic attractions in crystalline salts, such as sodium chloride, are formed by<em><u> </u></em><em><u>transfer of electrons</u></em> between positive and negative ions.

<h3><u>Explanation;</u></h3>
  • <u><em>Crystalline salts such as sodium chloride are formed as a result of ionic bonds. </em></u>Ionic bonds are types of bonds that are formed between non metals and non metals as a result of transfer of electrons.
  • <em><u>Transfer of electrons occurs when one atom involved in ionic bond formation looses electrons and the other gains electrons.</u></em> The result is that both atoms form ions, where one is a positively charged ion (cation) while the other is a negatively charged ion (anion). T<em><u>he attraction between the cation and anion results to the formation of ionic bond which results to formation of crystalline structures such as sodium chloride.</u></em>

What occurs in the space when a massive object undergoes a change in its motion?
Lorico [155]

Gravitational waves are emitted in the space when a massive object undergoes a change in its motion.

Gravitational waves are emitted. Bends spacetime, ripples travel outward from a gravitational source at the speed of light. The more massive the object and greater its acceleration, the stronger the resulting gravitational wave.

Therefore, A change in motion produces gravitational waves.

Definition of Gravitational waves:

Gravitational waves are disturbances or ripples in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light.

A body of mass m1 = 1.5 kg moving along a directed axis in the positive sense with a velocity
larisa86 [58]

Answer:

3.71 m/s in the negative direction

Explanation:

From collisions in momentum, we can establish the formula required here which is;

m1•u1 + m2•v2 = m1•v1 + m2•v2

Now, we are given;

m1 = 1.5 kg

m2 = 14 kg

u1 = 11 m/s

v1 = -1 m/s (negative due to the negative direction it is approaching)

u2 = -5 m/s (negative due to the negative direction it is moving)

Thus;

(1.5 × 11) + (14 × -5) = (1.5 × -1) + (14 × v2)

This gives;

16.5 - 70 = -1.5 + 14v2

Rearranging, we have;

16.5 + 1.5 - 70 = 14v2

-52 = 14v2

v2 = - 52/14

v2 = 3.71 m/s in the negative direction

What is the initial vertical velocity?
Marat540 [252]

Answer:

Thus, any projectile that has an initial vertical velocity of 21.2 m/s and lands 10.0 m below its starting altitude spends 3.79 s in the air.The initial vertical velocity is the vertical component of the initial velocity: v 0 y = v 0 sin θ 0 = ( 30.0 m / s ) sin 45 ° = 21.2 m / s .

The density of the nugget is 19 g/cm^3 and is made of gold

Explanation:

The density of an object can be calculated as

d=\frac{m}{V}

where

d is the density

m is the mass

V is the volume of the object

We have to note that density of an object actually depends on the material the object is made of (therefore, two objects made of the same material can have different mass and different volume, but they have same density).

For the nugget in this problem, we have:

mass: m = 38 g

volume: V=2 cm^3

So, its density is

d=\frac{38}{2}=19 g/cm^3

And by looking at the table, we see that this value corresponds approximately to the density of gold, so the nugget is made of gold.
