The gravitational force on Mars is about one-third that of Earth's gravitational force. If a space probe has a mass of 300 kg and a weight of about 660 pounds on Earth, what would be the mass and approximate weight of this probe on Mars?
Mass = 300 kg, weight = about 220 pounds
The graph compares the density, in grams per cubic centimeter ( ) g/cm3 , of four different substances.Based on information from the graph, which of the following best compares the physical properties of two of the substances?
Substance Y would have less mass than substance Z would have if they had the same volume.
Look at the two pictures below. They show what happened when two solid blocks were each put in a jar containing a liquid. Based just on what you can see in the pictures, what can you say about the blocks and the jars?
The block in jar 1 is floating lower in its liquid than is the block in jar 2.
When a helium balloon rises in the air, it expands. If the volume of the balloon doubles, what happens to the density of the helium inside it?
The density decreases by half
Imagine that the block shown below is made of pure gold.If Ana cuts this block into two equal pieces, which of these statements best describes the pieces?
The density of each piece is the same as that of the original block.
