Explanation: energy cant be destroyed no matter what and no energy is being created
I hope this helps a thank and a brainlist would be greatly appreciated
<span>Add the river’s velocity to the boat’s velocity.</span>
You already told us that its speed is constant. That's one part of acceleration.
The other part of acceleration is the direction it's moving.
If it's rolling in a straight line, then there's no acceleration.
If it's curving left or right, then that's acceleration.
Answer:
1) Addition of a catalyst
2) To change the reaction rate of slope B to look like slope A, simply add a catalyst to speed up the rate of reaction, giving you a higher amount of products in a shorter amount of time (line A)
Explanation:
1 and 2)Two things can alter the rate of a reaction, either the addition of a catylist which will not alter the composition of the products or reactants, but will accelerate the reaction time, or an increase in temperature will also increase the rate at which a reaction will occur.
You could choose temperature also and have the same result, it's your choice both are correct, but catalyst is the easiest.
A heat engine is a device that uses heat to produce useful work.
