A book on a shelf
b)
A rock sitting on the ground

3.
A probe traveling through outer space is moving at a constant velocity. Which statement applies to the motion of this probe?
a)
An unbalanced force is acting on the probe, causing it to accelerate.
b)
The probe will undergo constant acceleration until a force acts on it.
c)
The probe will continue on its current path until an unbalanced force acts on it.
d)
The force that makes the probe move through space is equal to its mass divided by its velocity

7.
Power grids use alternating current (AC) in transmission and distribution systems. Which statement explains why AC is used instead of direct current (DC)?
a)
Transmission wires cannot carry enough direct current to supply the needs of the power grid.
b)
The voltage can be changed in an alternating current system to transfer energy more efficiently.
c)
Electrical energy must be transmitted as alternating current because that is how it is produced at power plants.
d)
Direct current would not be useful to electric company customers because appliances operate on alternating current.

Yolanda learned the following about acids:
• They are made of elements from the periodic table.
• Most contain hydrogen.
• Very reactive elements tend to form stronger bonds.
• In general, the weaker the bond between hydrogen and another element in an acid, the stronger the acid will be.
Yolanda then studied the elements in group 17 of the following periodic table. Based on what Yolanda learned, which acid formed from an element in group 17 is weakest?
