No because you are supposed to do this
T for time and V for velocity or acceleration so what you do is take the two numbers
D= 3/12 it goes 12 meters every 3 seconds so you devide 12/3
So for every second the ball roles 4 meters!
Hope this helps! :)
The statement above is TRUE.
When heat is added to a substance, the heat increases the kinetic energy of the particles of the substance and enable to vibrate or move faster, this usually increase the temperature of the substance. However, adding heat does not always increase the temperature of a substance. For instance, during the process of boiling point of water, the additional heat energy that is added to the water is used to break the chemical bonds in water and not to increase the temperature of water.<span />
The mass number of this particular element is 37
An element with 17 protons will ALWAYS be chlorine.
The mass number is found by adding the element’s protons and neutrons.
protons+neutrons=mass number
Here is the math if needed,
17+20=37
Therefore the mass number is 37
I hope this helped!
Density of boat =
=
= 0.88 g / cm³
Since the density of water is greater than the density of the boat ( 1 > 0.88) then that means,
the boat will NOT sink.B.
Answer:
Explanation:
Hello!
In this case, since the writing of a net ionic equation first implies writing the complete molecular equation:
We can see that HCl and MgCl2 are ionized because they are aqueous, thus we write:
In such a way, we can cancel out the chloride ions as they are the spectator ones to obtain the net ionic one:
Best regards!
