Answer:
9.8 m.s^-2
Explanation:
The ball starts from rest which is the initial velocity and the final velocity is 14.7 m/s. So, first take the final velocity and subtract it with the initial velocity over the time and write your answer in meters per square second.
Answer:
which two questions you did not post them
The final temperature on the block is 25 degrees.
Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.
Data given;
- M1 = 3.33g
- T1 = 25 degrees
- M2 = 44g
- T2 = 25 degree
- C1 = 124.5 J mol K
- C2 = 0.89 J/g K
<h3>Heat Transfer</h3>
Applying the principles of heat transfer,
Heat loss = Heat gain
![m1c1(T1 - T3) = m2c2(T3 - T2)\\3.33*124.5*(25.0 - T3) = 44*0.89*(T3 - 25)\\10364.625 - 414.585T3 = 39.16T3 - 979\\10364.625+979 = 414.585T3 +39.16T3\\11343.25 = 453.745T3\\T3 = \frac{11343.25}{453.745} \\T3 = 24.999\\T3 = 25](https://tex.z-dn.net/?f=m1c1%28T1%20-%20T3%29%20%3D%20m2c2%28T3%20-%20T2%29%5C%5C3.33%2A124.5%2A%2825.0%20-%20T3%29%20%3D%2044%2A0.89%2A%28T3%20-%2025%29%5C%5C10364.625%20-%20414.585T3%20%3D%2039.16T3%20-%20979%5C%5C10364.625%2B979%20%3D%20414.585T3%20%2B39.16T3%5C%5C11343.25%20%3D%20453.745T3%5C%5CT3%20%3D%20%5Cfrac%7B11343.25%7D%7B453.745%7D%20%5C%5CT3%20%3D%2024.999%5C%5CT3%20%3D%2025)
From the calculation above, the final temperature on the block is 25 degrees.

Answer:
The two main consumers of water are thermoelectric power and irrigation. So I'd say don't water your lawn as much and always turn your lights off when your not using them. And you could always take shorter showers.
