The atomic mass is always equal to the sum of protons and neutrons in the nucleus. If you add the number of protons and neutrons (8 + 10) = 18 you will find that the atomic mass is 18.
Answer:
15.88m/s
Explanation:
At the top of the roller coaster you will have three forces acting on the roller-coaster. See the image below. Fc is the centripetal force (for an object in circular motion), Fg is the gravitational force, and Fn is the normal force. To achieve the minimum speed we assume the roller-coaster is barely touching the vertical loop and so the normal force is zero. This leaves two acting forces.

Answer:</h2>
If you triple the charge, the electric potential is 3V.
<h2>
Explanation:</h2>
If you triple the charge, the electric potential is 3V. Put another way, the value of the electric potential at the same location is tripled if the strength of the charge is tripled.
<em>But why this is true?</em>
Well, the potential V due to a single point charge q is:

If the strength of the charge is tripled means that our new q1=3q, therefore:


So you can see that in fact if you triple the charge, the electric potential is 3V.
Answer:
Air and ice
Explanation:
convection, process by which heat is transferred by movement of a heated fluid such as air or water.
Everyday Examples of Convection:
radiator - A radiator puts warm air out at the top and draws in cooler air at the bottom.
steaming cup of hot tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air.
ice melting - Ice melts because heat moves to the ice from the air.
Answer:
it will have a stronger attraction force
