Answer:
It will be more spread out
Explanation:
As you increase the height, the gravitational potential energy increases and it gets faster, causing it to hit the ground harder. This in turn makes the 'splat' be more spread out
Answer:
Potential Energy stored = mgh ; m : mass, g : gravitational acceleration (let 10m/s) , h : height
Hence,
Energy Stored in the ball = mgh = (2*10*4) J
= 80 Joules!
Answer:
The bond energy of F–F = 429 kJ/mol
Explanation:
Given:
The bond energy of H–H = 432 kJ/mol
The bond energy of H–F = 565 kJ/mol
The bond energy of F–F = ?
Given that the standard enthalpy of the reaction:
<u>H₂ (g) + F₂ (g) ⇒ 2HF (g)</u>
ΔH = –269 kJ/mol
So,
<u>ΔH = Bond energy of reactants - Bond energy of products.</u>
<u>–269 kJ/mol = [1. (H–H) + 1. (F–F)] - [2. (H–F)]</u>
Applying the values as:
–269 kJ/mol = [1. (432 kJ/mol) + 1. (F–F)] - [2. (565 kJ/mol)]
Solving for , The bond energy of F–F , we get:
<u>The bond energy of F–F = 429 kJ/mol</u>
Answer:
C. This is because he is asking him to disregard what his parents are saying and listen to his own values. This is not morally wrong, just the answer that works in that situation.
