Answer :The mass number is 56.

Explanation:

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons = 26+ 30 =56

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

Atomic number = Number of electrons = Number of protons = 26

Hence, neutrons and protons affects the mass number and thus the mass number will be 56.

Label these as balanced or unbalanced:
kvasek [131]

Answer:

  1. A book lying on a table  - Balanced force
  2. An airplane cruising in level flight  - Balanced
  3. A rock falling from a cliff  - Unbalanced force
  4. A bridge collapsing in an earthquake  -  Unbalanced force
  5. A man sitting on a park bench  - Balanced force
  6. A space shuttle taking off  - Unbalanced force
  7. A car maintaining a constant speed on a straight road  - Balanced force
  8. An airplane landing - Unbalanced force

Explanation:

Usually, one or more forces act on a body at an instant of time. When these forces acting on a body and bring the body in the equilibrium position, the force is said to be balanced. The unbalanced force changes the equilibrium state of the body.

As in the case of an airplane cruising in a level flight, the weight of the plane will be equal to the lift force and the thrust is equal to the drag. So the plane is experiencing a balanced force.

Which is younger, the rock layers or the fault?
jeka94
<h2>FAULT</h2>

The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts. The fault labeled 'E' cuts through all three sedimentary rock layers (A, B, and C) and also cuts through the intrusion (D). So the fault must be the youngest formation that is seen.
