Answer:
Solubility
Explanation:
Material becomes soluble in solvent and disappears.
Answer:
D) 11 m/s
Explanation:
We have to calculate the velocity of the hot dog with respect to the observer still outside the train. This velocity will be given by:

where
is the velocity of the train (towards right)
is the velocity of the man (towards right)
is the velocity of the hot-dog (towards left, so we put a negative sign)
By replacing the numbers into the equation, we find

and the positive sign means the velocity is toward right.
Answer:

Explanation:
<u>Accelerated Motion</u>
It occurs when an object changes its speed over time. If the changes in speed are uniform, then the acceleration is constant, positive if the speed increases, negative if the speed decreases.
The acceleration is calculated as follows:

The aeroplane starts with a speed of vo=62 m/s and reaches a speed of vf=6 m/s in t=35 s.
The acceleration is:


I can help just a bit i had this question before but i got it kinda right but wrong but now i know. First, write down each definition and look of examples and also search for the graphs for each one then write your summary about the question. I hope this kinda helps i don’t wanna get the question wrong for you :)
