Answer:
add 7.5L of water
Explanation:
M1×V1=M2×V2
M is molarity, V is volume
0.7 × 10 = 0.4 × V2
V2= 17.5L
vol. of water to add= 17.5 - 10 = 7.5L
Answer:
4-wheeler
Explanation:
I was thinking that you could say this:
My design is that the 4-wheeler will detect, with the help of technology, when something is approaching or you are very close to it. As the object gets closer, it will beep faster and louder. When the 4-wheeler beeps really fast and really loud, it means that you are about to crash or you are in danger. It will stop and launch an airbag so you stay safe. When the 4-wheeler stops, it will make a signal to let people know that you have stopped.
I am so sorry if this wasn't the response that you were looking for.
