No mate. Ca denotes calcium. Ca3 means three calcium atoms. N denotes nitrogen. N2 denotes two nitrogen atoms

No, there are not any carbon atoms inside this compound.

The compound is Ca_3N_2. This means there are 3 "Ca" atoms and 2 "N" atoms.

  • Ca is calcium
  • N is nitrogen

Thus, none of the elements in this compound are carbon, meaning there are no carbon atoms. Let me know if you need any clarifications, thanks!

A child tugs on a rope attached to a 0.62 kg toy with a horizontal force of 16.3 N. A puppy pulls the toy in the opposite direct
sattari [20]

Answer:

a=51.77\ m/s^2

Explanation:

Given that,

The mass of a toy, m = 0.62 kg

Force with which a child pull the toy = 16.3 N

The force with which the toy pulled in the opposite direction = -15.8 N

We need to find the acceleration of the toy. Let F be the net force acting on the toy. It is equal to :

F = 16.3 N - (-15.8 N)

= 32.1 N

Let a be the acceleration of the toy. Using Newton' second law of motion to find it.

F = ma

a=\dfrac{F}{m}\\\\a=\dfrac{32.1}{0.62}\\\\a=51.77\ m/s^2

So, the acceleration of the toy is 51.77\ m/s^2.

a set of water travels at 10 m/s, and 5.0 waves pass you in 2.0s. what is the wavelength of the waves?
Alecsey [184]
Well, I think the answer would be 4 meters because the speed is in meters per second and the frequency is 5 waves every 2 seconds. 
Wavelength = Speed/Frequency
I think the frequency is 2.5 waves a second but that's not something I'm 100% sure about.
I hope this helps though.

Which property of matter is an extensive, rather than an intensive, property of matter?.
leonid [27]

 A property known as an extensive property depends on the quantity of materials in a sample. A couple of instances of extensive attributes are mass and volume. A property of matter that is intensive depends solely on the type of matter in a sample and not on the quantity.

<h3>Which of the following is intensive as opposed to extensive?</h3>

An intense property is a structural characteristic of a system that is independent of the system's size or the volume of its constituent parts. Volume and internal energy are extensive qualities while density, pressure, and temperature are intensive ones.

<h3>What is an illustration of a extensive property?</h3>

The features that depend on the amount of matter present are referred to as extensive properties. Volume, mass, internal energy, etc. are some examples.

<h3>What are some instances of a substance's extensive and intensive properties?</h3>

Temperature, T, refractive index, n, density, and object hardness are a few examples of intensive attributes. In contrast, subsystems' comprehensive attributes, such as mass, volume, and entropy, are additive. However, not all physical characteristics of matter fit within those categories.

A new ride being built at an amusement park includes a vertical drop of 126.5 metered. Starting from rest, the ride vertically d
Delvig [45]

Answer:

The amount of Potential Energy lost in the form of Thermal Energy is equal to 41.64 MJ.

Explanation:

mass of the cart and passengers = m = 3.5*10⁴ kg

Height = h = 126.5 m

g = 9.8 ms⁻²

v = 10 ms⁻¹

At the top position the Total energy of the ride is in the form of potential energy given as:

P.E = mgh

= 3.5*10⁴*9.8*126.5

= 43389500 J

At the bottom of the drop, all the Potential Energy will be converted into K.E as the ride develops speed given as:

K.E = 0.5*m*v²

= 0.5*3.5 x 10⁴*100

= 1750000 J

The K.E is much less than the P.E energy even though all the P.E of the ride has been converted. The loss of energy is due to the formation of thermal energy which can be calculated as:

Thermal Energy lost = Total energy in the form of P.E(top) - Total energy in the form of K.E(bottom)

= 43389500 -  1750000

= 41639500 J

= 41.64 M J approx             M J = mega joule = 10⁶ J
