Oh wait if what I said is wrong actually and now of what I'm telling you right now is really actually the answer... so when 108 grams of water at a temperature of 22.5c is mixed with 65.1 grams of water at an unknown temperature,the final temperature of the resulting mixture of 47.9c.
Answer:
Explanation:
initial height of the ball is given as
initial speed of the ball is given as
now we know that
now by energy conservation we can say
initial kinetic energy + initial potential energy = final kinetic energy + final potential energy
Answer:
I believe it is not a chemical change for the components are not changing.
This excerpt from thoughtco.com states that for it to be a chemical change, the atoms would be rearranged.
<em>In other words, a chemical change is a chemical reaction involving the rearrangement of atoms. While a physical change can often be reversed, a chemically change typically cannot be, except through more chemical reactions. When a chemical change occurs, there is also a change in the energy of the system.</em>
So, in this case, they are not being rearranged, just combined to form one big fruit salad.
Answer:
M1L2T-2
Explanation:
In the equation above 1/2 is a constant and constants do not affect the dimensional formula of any quantity.
Answer:
The requested distance is 4320 meters
Explanation:
We can use the formula for velocity in this movement at constant velocity (v), which is defined as the quotient between the distance covered divided the time it took:
Since we know the velocity and the time, we can solve for the distance:
