Answer:
1)
2) The dependent variable = The time it takes for one pendulum swing
3) The independent variable = The length of the pendulum string with weight at the bottom
Explanation:
The relationship between the length of the pendulum string and the time it takes for one pendulum swing is giving as follows;
Where;
T = The period of oscillation = The time to complete one oscillation =Two swings of the pendulum
L = The length of the pendulum
g = The acceleration due to gravity
Therefore, the time it takes for one pendulum swing is directly proportional to the square root of the length of the pendulum
The dependent variable = The time it takes for one pendulum swing
Th independent variable = The length of the pendulum string with weight at the bottom.

Answer:
Explanation:
I just had this question on my test
Answer:
A4
B1
C3
D2
Explanation:
A4: dispersion forces occur in everything as it is variations in the electron cloud. They are very weak and are the only intermolecular force in a non-polar molecule such as CH4.
B1: Dipole Dipole forces occur between polar molecules. The polarity of the molecule creates a dipole which can attract each other. they are stronger then dispersion forces. CBr2Cl2 is a polar molecule.
C3: hydrogen bonding is a special type of dipole-dipole force and are pretty strong. They can only occur between H-N, H-O, and H-F bonds. NH3 has N-H bonds.
D2: ion dipole forces occur between a polar molecule and ions. They mainly occur when charged species (ions) are in a polar solvent but there are likely less common examples.
I hope this helps. Let me know if anything is unclear.
