Construct an hypothesis <em /><em>(Because </em>the magnet wasn't attracted to the door, the door must be non-magnetic.) He has already made an observation (the magnent didn't stick), and already asked a question (<em>Why </em>didn't the magnent stick). However, he has not explained the results (there is no experiment yet).
Answer:
Inside a femur bone found in the woods,
saliva of gum
Answer:
stone A is diamond.
Explanation:
given,
Volume of the two stone = 0.15 cm³
Mass of stone A = 0.52 g
Mass of stone B = 0.42 g
Density of the diamond = 3.5 g/cm³
So, to find which stone is gold we have to calculate the density of both the stone.
We know,
density of stone A
density of stone B.
Hence, the density of the stone A is the equal to Diamond then stone A is diamond.
<h2><u>ANSWER</u></h2>
The simplest definition of a black hole is an object that is so dense that not even light can escape its surface. If we squished the Earth's mass into a sphere with a radius of 9 mm, the escape velocity would be the speed of light. Just a wee-bit smaller, and the escape velocity is greater than the speed of light.
