suppose a scientist found a new matal-like substance in the desert. He determined its mass to be 20 grams. The volume was determ ined by water displacement to be 5 cm^3. What is the density of the substance? Will it sink or float in liquid water ( 1g/cm^3)?
1 answer:
Density = (mass) / (volume)
Density = (20 g) / (5 cm³)
<em>Density = 4 g/cm³ </em> .
The density of the substance is greater than the density of water. A lump of the substance <em>will sink in water </em>, <u>unless</u> the lump is formed into a shape that displaces 20 cm³ of water or more, such as a tiny boat shape.

The correct answer is C
Answer:
m<2 = 86
Explanation:
Vertical angles means the angles are equal to each other so:
<1 = <2
17x + 1 = 20x - 14
17x - 20x = -14 - 1
-3x = -15
x = 5
m<2:
20x - 14
20(5) - 14
100 - 14
86
Answer:
240 Newtons
Explanatiohn:
f = m × a
f = 120 × 2
f = 240 Newtons
<h3>The force is 240 Newtons</h3>
Answer:
Explanation:
we know that
as we see that
relative error
Where X_1 IS HEIGHT OF ROCK
IS THE HEIGHT OF ROAD
= uncertainity in measuring distance
Putting all value to get uncertainity in angle
solving for we get
