**Answer:**

A valence number of 1 means that an alement will generally react to lose one electron to obtain a full outer shell.

Group two elements are assigned a valence number of 2. A valence number 2 means that a group two elements will generally react to lose two electrons to obtain a full outer shell.

**Explanation:**

Hope it helps

Because no matter what direction you are heading, gravity will pull downwards. Since the same object is dropping from the same height and weighs the same, gravity will pull both objects closer to earth at the same time and speed.

**Answer:**

B. Increases

**Explanation:**

Momentum is given as . Since is maintained, as the velocity decreases, the momentum decreases, and similarly, as the velocity increases, the momentum increases.

**The current will double**

**Explanation:**

The relationship between voltage and current in an electric circuit is given by the following equation (Ohm's law):

where

V is the voltage

I is the current

R is the resistance

making R the subject,

Since in this experiment the resistance is kept constant, we can write:

where

is the voltage in the 1st experiment

is the voltage in the 2nd experiment

are the currents in the 1st and 2nd experiment

We can re-arrange the equation as

This means that the current will double in the 2nd experiment.
