Mass of oxygen stays the same.
You're talking about a <em>tornado</em>.
It's not so much the low pressure that's so dangerous in the center of a tornado. It's more a matter of the high winds that are <em>caused </em>by the low pressure.
Explanation:
Newton has given three laws. The laws of motion are as follows :
- Newton's first law
- Newton's second law
- Newton's third law
The first law of Newton states that an object at rest will remain at rest and an object at motion will remain in motion until and unless an unbalanced force acts on it. Hence, this is the required solution.
Answer:
f = 15 N
Explanation:
It is given that, when you push with a horizontal 15-N force on a book that slides at constant velocity, a frictional force also acts on it. Frictional force is an opposing force. The magnitude of applied force and frictional forces are same. So, the force of friction on the book is equal to 15 N.
