Answer:
H₂0_{(s)} + heat → H₂O(l)
Explanation:
An ENDOTHERMIC reaction is a chemical reaction in which heat is absorbed by the reactants. As such the product is usually cooler than the products. In the equation above (the answer), heat is on the reactant side of the equation thus indicating that heat is absorbed by the reactants.
On the other hand, in the first equation heat is on the product side of the equation which is consistent with an Exothermic reaction.

<h3>
Answer:</h3>
30 m/s
<h3>
Explanation:</h3>
<u>We are given:</u>
Initial Velocity (u) = 0 m/s
Acceleration of the Car (a) = 3 m/s²
Time Interval (t) = 10 seconds
<u>Speed of the Car After 10 seconds:</u>
From the First equation of motion:
v = u + at
replacing the given values
v = 0 + (3)(10)
v = 30 m/s
Hence, the car is moving at a velocity of 30 m/s after 10 seconds
1. The red ball was potential energy until it was hit by the pendulum converting into kinetic energy.
2. The 5 pounds was a potential energy, until the rope was cut by the scissors, this made the 5 pounds become kinetic energy.
3. The bucket was a potential energy, till the books landed in it causing it to fall, this became kinetic energy
Answer:
mean=5
median=3
range=8
Explanation:
mean- add em up and divide by the number of numbers
so 2+2+3+8+10=4+11+10+15+10=25
There are 5 numbers so 25/5=5 is the mean
median- middle (or average of middles if two middles) after data arranged from least to greatest
It already is and there is one middle so the median is 3
range=greatest minus smallest
So the range is 10-2=8.
