The chocolate in your favorite candy bar has the chemical formula: C7H8N4O2. What elements are present in this formula? Carbon,

hydrogen, nitrogen, oxygen.
How many atoms of each element are in this molecule? 7 carbon atoms, 8 hydrogen atoms, 4 nitrogen atoms, and 2 oxygen atoms.


Using some of the trends that you described in question 2, what patterns do you notice between these elements on the periodic table? (Hint!: Be sure to refer to your periodic table to answer this question!)

A 2 kg ball is moving 3 m/s when it starts rolling up a hill.
AURORKA [14]

Answer:

the height reached is = 0.458 [m]

Explanation:

We need to make a sketch of the ball and see the location of the reference point where the potential energy is zero. But the kinetic energy will be defined by the following expression:

Ek=\frac{1}{2} *m*v^{2} \\where:Ek= kinetic energy [J]\\m = mass of the ball [kg]\\v = velocity of the ball [m/s]

Replacing the values on the equation we have:

Ek=\frac{1}{2}*(2)*(3^{2} )\\ Ek=9[J]\\

This kinetic energy will be transformed in potential energy in the moment when the ball starts to rolling up. Therefore the maximum height reached by the ball depends of the initial velocity given to the ball.

Ek=Ep\\where\\Ep=potential energy [J]\\Ep=m*g*h\\where\\g=gravity = 9.81[m/s^2]\\h=height reached [m]\\

Now we have:

h=\frac{Ep}{m*g} \\h=\frac{9}{2*9.81} \\\\h=0.45 [m]

In that moment when the ball reach the 0.45 [m] the potencial energy will be maximum and equal to the kinetic energy when the ball has a velocity of 3[m/s]

What is the difference between continuous and a discontinuous spectrum?
aleksklad [387]
A continuous spectrum contains all the wavelengths 

A discontinuous spectrum has strips of specific colors and can be used to identify the elements making it.

hope this helps

Does a thicker core make an electromagnet stronger?
goldenfox [79]

Answer:

Yes

Explanation:

The core of an electromagnet serves to stabilize the magnetic field created by the wire. The thicker the core, the more metal there is to amplify the current. Therefore, a thicker core does make an electromagnet stronger. Hope this helps!
