The water gets cold because the ice cube is endothermic. Which means it takes in heat. It takes the warmth from the water and melts the ice cube which the ice cube releases coldness which cools down the water.
Answer:
Answer is given below:
Explanation:
<em>Given Data:</em>
mass = 80kg
acceleration = 4 ms
force = 800N
<em>Find out:</em>
friction = ?
<em>Formula</em><em>:</em>
F-friction = weight - f-net
<em>Solution:</em>
weight = (80)(10)
= 800 N
F-net = ma =(80)(4) = 320N
F-friction = weight - F-net
=800 N - 320N
=480N
<em>Answer</em> :
Friction = 480 N
Answer:
If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

Thats the answer I need brainliest PLEASE jk.
In the preparatory reaction that involves movement of pyruvic acid into mitochondria TAKES PLACE IN THE MITOCHONDRIAL MATRIX WHERE THE PYRUVIC ACID IS OXIDIZED AND CARBON DIOXIDE IS RELEASED. In this reaction, NAD+ is also reduced. The end products of a preparatory reaction are 4 NADH molecules, 4 hydrogen ions, 2 carbon dioxide molecules, 2 ATP molecules and 2 acetyl CoA molecules.
