Potable water is Fit to drink. It is both safe and healthy enough for consumer use.
Thermal energy is added to four identical<span> 1.0 kg </span>samples of water<span> at room temperature. Which of the following </span>increases in each sample<span>? average charge of an electron; average density of </span>a<span> nucleus; average mass of </span>a<span> proton; average speed of </span>a<span> molecule. Your answer: -. Answer: D - average speed of </span>a<span>molecule.</span>
Answer:
15 m/s
Explanation:
Given data
Initial velocity= 0m/s----------since the cart was at rest
Final velocity = 30m/s
time= 30 seconds
Required
the average speed
We know that the sum of the initial and final velocity is divided by 2 to find the average velocity
average velocity= 0+30/2
average velocity= 30/2
average velocity= 15 m/s
Hence the average velocity is 15 m/s
The skeletal system is a body system comprised of bone structures and tissues that help hold the body up. It also gives the body its shape - as if it was the framework. On top of that, it protects internal organs within the body.
Therefore, the skeletal system is a body system comprised of bone structures and tissues that give the body its shape and protects internal organs.
