Mass
Explanation:
They have masses ranging from about 5 to several tens of solar masses.
Answer: Speed
Explanation:
The speed of a body is the rate of distance (in metres) that it travels in one second. Hence, speed unlike velocity, is total distance travelled by the body without regard to direction divided by the total time taken.
i.e Speed = Distance / time taken
Thus, the standard international (SI) unit of speed is metres per second (m/s)
That could be an electromagnet,
and it could also be an solenoid.
4.22
Explanation:
The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.
The pH scale expresses the acidity or alkalinity of aqueous solutions.
- The pH scale ranges from 1 to 4
- An acidic solution will have a pH value less than 7
We have given a range of values between 4.22 to 4.40
This implies that the pH values of rainfall in this region falls between these extremes.
The least value 4.22 is the most acidic
The value 4.4 is the the least acidic
The lower the pH value, the more acidic a solution is.
